Answer: x=0.5

Step-by-step explanation: In order to solve this problem, you need to simplify the rest of the problem first. You can do this by dividing -7 by 2, which will result in -3.5, making the equation 3x-3.5=-5. If you add 3.5 to both sides, the equation becomes 3x = 1.5. If you divide 1.5 by 3, you are left with 0.5, so x=0.5.

Final answer:

The solution to the linear equation '3x minus 7 divided by 2 equals negative 5' is found by performing algebraic operations to isolate the variable, resulting in x = -1.

Explanation:

The question involves solving a linear equation which is a fundamental concept in mathematics. To solve the equation 3x minus 7 divided by 2 equals negative 5, you will perform algebraic operations to isolate the variable x. Here is a step-by-step process:

Applying this process, you can see that the original equation is satisfied when x = -1, which completes our solution.

Answer:

n = - 3

Step-by-step explanation:

We have to solve the equation [tex]2^{n} = \frac{1}{8}[/tex] for n.

Now, as the variable is in power, we will take a log on both sides.

So, [tex]2^{n} = \frac{1}{8}[/tex]

⇒ [tex]\log 2^{n} = \log \frac{1}{8}[/tex]

⇒ n log 2 = log 1 - log 8 {Since we know the property of logarithm [tex]\log a^{b} = b \log a[/tex] and [tex]\log \frac{a}{b} = \log a - \log b[/tex]}

⇒ n log 2 = -  log 2³ { Since, log 1 = 0}

⇒ n log 2 = - 3 log 2

⇒ n = - 3 (Answer)

Helena gave the answer as (7y²z + 6yz²- 5 - 3yz² + 2) which is equivalent to (7y²z + 3yz² - 3).

Step-by-step explanation:

Misha's group was asked to write an expression equivalent to  

7y²z + 3yz² - 3

When Mr. Chen checked their answers, he found only one to be correct.

And she was Helena.

Helena gave the answer as (7y²z + 6yz²- 5 - 3yz² + 2) which is equivalent to (7y²z + 3yz² - 3).  

Because, (7y²z + 6yz²- 5 - 3yz² + 2)

= 7y²z + (6yz² - 3yz²) - (5 - 2)  

= 7y²z + 3yz² - 3 (Answer)

Answer:

C

Step-by-step explanation:

First of all,

Since, from the graph we can see that the line is sloping upward, we know the correlation coefficient would be POSITIVE, so we can immediately eliminate choices A & B.

Now, the closer the correlation coefficient value is to 0, the less steep the line is. The closer it is to 1, the more steeper it is.

Looking at the graph, it isn't that flat, it is quite steep. So the correlation coefficient would be 0.8, NOT 0.1

So, answer choice C is right.

(1.25×4+3×2 )/((1/2)^3) = 88

Step-by-step explanation:

The solution to the equation 1.25×4+3×2 divided By (1/2) third power is 53 applying the order of operation PEMDAS.

To solve 1.25×4+3×2 divided By (1/2) third power, we first have to follow the order of operation, that is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), also known as PEMDAS.

Step 1: Solve the expressions in parentheses and the exponent. As there's none, we move to the next step.

Step 2: Solve the multiplication and division.
1.25×4 equals 5, then 3×2 equals 6, and then 1/2, to the third power, equals 0.125.
So our equation now reads 5+6 divided by 0.125.

Step 3: Execute the division operation. 6 divided by 0.125 equals 48.
Our equation now reads 5 + 48.

Step 4: The last step is addition. 5 + 48 equals 53. So, the answer to the equation 1.25×4+3×2 divided By (1/2) third power is 53.

Answer:

x = -22 , y = -26

Step-by-step explanation:

Solve the following system:

{y = x - 4 | (equation 1)

y - 2 x = 18 | (equation 2)

Express the system in standard form:

{-x + y = -4 | (equation 1)

-(2 x) + y = 18 | (equation 2)

Swap equation 1 with equation 2:

{-(2 x) + y = 18 | (equation 1)

-x + y = -4 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{-(2 x) + y = 18 | (equation 1)

0 x+y/2 = -13 | (equation 2)

Multiply equation 2 by 2:

{-(2 x) + y = 18 | (equation 1)

0 x+y = -26 | (equation 2)

Subtract equation 2 from equation 1:

{-(2 x)+0 y = 44 | (equation 1)

0 x+y = -26 | (equation 2)

Divide equation 1 by -2:

{x+0 y = -22 | (equation 1)

0 x+y = -26 | (equation 2)

Answer:

F(f) = 15t + 35 represents the total amount of savings your friend would make in t weeks.

F(d) = 10t + 90 represents the total amount of saving you, darian, would make in t weeks.

When you graph the equations, plugging in different values for t, you can see that the graphs  intersect at (11,200). This means that at 11 weeks, both you and your friend have the same amount of money saved up, $200.  They will not have the same amount of money in 10 weeks.

Answer:

[tex]y=15x+35[/tex]

Step-by-step explanation:

If you begin with $90 and add $10 each week, then we express it as

[tex]y=10x+90[/tex]

Where [tex]x[/tex] refers to weeks and [tex]y[/tex] refers to the total amount of money in you savings account.

On the other hand, your friend begins with $35 and deposits $15 each week, the equation that expresses your friend's savings is

[tex]y=15x+35[/tex]

Therefore, the sytem of linear equation that models this situation is

[tex]y=10x+90[/tex]

[tex]y=15x+35[/tex]

The graph attached shows this system. There you can notice that the solution is (11, 200), which means in 11 weeks both will have the same amount saved.

Therefore, your friend is wrong, because after 10 weeks you won't have the same amount.

Step-by-step explanation:

Answer:

165

Step-by-step explanation:

First we need to find the area of the field, A = r^2 * pi

The radius is 290 / 2 = 145 feet

A = 145 * 145 * 3.14 = 66018.5 sqr feet

One bag covers 400 sqr feet

Divide the Area by 400 sqr feet to find number of bags needed.

66018.5 / 400 = 165

He will need at least 165 bags to cover the field

Answer:

4 bags

Step-by-step explanation:

We need to find the area of the circular field. To do this, we use the formula

A=piR^2     (pi multiplied by radius squared)

The radius is going to be 290/2 which is 145 which we plug into the equation.

A=pi145^2

The next step is to square 145, getting 21025. But now we need to multiply that by pi (3.14). We get 66018.5 as the answer.

Now we need to figure out how many square feet one bag can cover. To do this, we multiply 400 by 50 (because one pound can cover 400ft and one bag has 50 pounds). We get 20000 as the amount one bag of grass seed can cover. Now we need to divide 66018.5 by 20000. We get 3.300925. But the groundskeeper can't buy a decimal of a bag so we have to round up to 4 bags of grass seed.

Answer:

The speed of Sharma is slower than the speed of Brandi

I.e ∵   4.67 miles per hour  [tex]<[/tex] 5 miles per hour

      ∴  [tex]S_2[/tex] [tex]<[/tex] [tex]S_1[/tex]

Step-by-step explanation:

Given as :

The distance cover by Brandi = [tex]D_1[/tex] = 2 [tex]\frac{1}{2}[/tex] =[tex]\frac{5}{2}[/tex]

The Time taken by Brandi for jogging =  [tex]T_1[/tex] = 30 minutes =[tex]\frac{1}{2}[/tex] hour

Let the speed of Brandi = [tex]S_1[/tex] = [tex]\dfrac{\textrm Distance }{\textrm Time}[/tex]

or,  [tex]S_1[/tex] = [tex]\dfrac{\textrm  [tex]D_1[/tex]  }{\textrm   [tex]T_1[/tex] }[/tex]

Or.  [tex]S_1[/tex] = [tex]\frac{\frac{5}{2}}{\frac{1}{2}}[/tex]

∴   [tex]S_1[/tex] = 5 miles per hour

Again

The distance cover by Sharma = [tex]D_2[/tex] = 3 [tex]\frac{1}{2}[/tex] =[tex]\frac{7}{2}[/tex]

The Time taken by Sharma for jogging =  [tex]T_2[/tex] = [tex]\frac{3}{4}[/tex] hour

Let the speed of Sharma = [tex]S_2[/tex] = [tex]\dfrac{\textrm Distance }{\textrm Time}[/tex]

or,  [tex]S_2[/tex] = [tex]\dfrac{\textrm  [tex]D_2[/tex]  }{\textrm   [tex]T_2[/tex] }[/tex]

Or.  [tex]S_2[/tex] = [tex]\frac{\frac{7}{2}}{\frac{3}{4}}[/tex]

∴   [tex]S_2[/tex] = [tex]\frac{14}{3}[/tex] = 4.67 miles per hour

Now, ∵   4.67 miles per hour  [tex]<[/tex] 5 miles per hour

         ∴  [tex]S_2[/tex] [tex]<[/tex] [tex]S_1[/tex]

So, Sharma jogged at slower late

Hence The speed of Sharma is slower than the speed of Brandi Answer

x + y = 16

16x + 9y = 165

Multiply first equation by 9 and subtract the equations.

9x + 9y = 144

-(16x + 9y = 165)

-7x = -21

x = 3

Now substitute this x value into the first equation

x + y = 16

3 + y = 16

y = 13

Lance and Mary will need approximately $12,995 for a down payment on the property.

To calculate the amount of money needed for a down payment, you need to find 20% of the property cost. In this case, the property cost is $64,975.

Step 1: Convert 20% to a decimal by dividing it by 100: 20/100 = 0.2

Step 2: Multiply the property cost by 0.2: $64,975 * 0.2 = $12,995

Therefore, Lance and Mary will need approximately $12,995 for a down payment on the property.

Answer:

D

Step-by-step explanation:

The diagram shows the rectangle with vertices at A(3,4), B(3,7), C(4,7) and D(4,4).

1. Rotate rectangle ABCD by 180° about the point (3,4) (vertex A). This rotation has the rule:

[tex](x,y)\rightarrow (6-x,8-y)[/tex]

So, the image points have the coordinates A'(3,4), B'(3,1), C'(2,1) and D'(2,4)

2. Dilate by a scale factor of 2 with the center of dilation at origin. This dilation has the rule:

[tex](x,y)\rightarrow (2x,2y)[/tex]

So, the image points have the coordinates A''(6,8), B''(6,2), C''(4,2) and D''(4,8)

3. Reflect it over the y-axis. This reflection has the rule:

[tex](x,y)\rightarrow (-x,y)[/tex]

So, the image points have the coordinates A'''(-6,8), B'''(-6,2), C'''(-4,2) and D'''(-4,8) that are exactly the coordinates of the second rectangle shown.

Thus, correct option is option D.

Answer:

Part a) Camilo is 34 years old and Juan is 28 years old

Part b) The difference between Camilo's age and Juan's age is 6 years

Part c) The sum of the ages of Camilo and Juan not coincide with the age of Andres' grandmother

Step-by-step explanation:

The question in English is

If Camilo is 6 years older than Juan, Juan is 7 years younger than Andrés and Andrés is 35 years old .

Part a)  How old is Camilo and how old is Juan? raises the equation.

Part b) What's the difference between Camilo's age and Juan's age?

Part c) If Andres's grandmother is 65 years old, does the sum of the ages of Camilo and Juan coincide with the age of Andres' grandmother?

Part a)  How old is Camilo and how old is Juan? raises the equation.

Let

x -----> Camilo's age

y -----> Juan's age

z -----> Andres's age

we know that

[tex]x=y+6[/tex] -----> equation A

[tex]y=z-7[/tex] -----> equation B

[tex]z=35[/tex] -----> equation C

Find the value of y

substitute the value of z in the equation B

[tex]y=35-7=28[/tex]

Find the value of x

substitute the value of y in the equation A

[tex]x=28+6=34[/tex]

therefore

Camilo is 34 years old and Juan is 28 years old

Part b) What's the difference between Camilo's age and Juan's age?

Subtract Juan's age from Camilo's age

so

[tex]x-y=34-28=6\ years[/tex]

Part c) If Andres's grandmother is 65 years old, does the sum of the ages of Camilo and Juan coincide with the age of Andres' grandmother?

Adds Camilo's age and Juan's age

[tex]x+y=34+28=62\ years[/tex]

[tex]62\ years\neq 65\ years[/tex]

therefore

The sum of the ages of Camilo and Juan not coincide with the age of Andres' grandmother

Answer:

Area = 374.1  sq. in.

Step-by-step explanation:

A trick to solve this would be to know the area of a hexagon formula and plug the known information.

First, of all, if we count the number of sides, we see that we have 6 sides.

6 sided polygon is a HEXAGON, which has area formula of:

[tex]A=\frac{3\sqrt{3} }{2} a^2[/tex]

Where

a is the side length

Given, the side length is 12 inches ( a= 12), we simply substitute into formula and find area of hexagon shown:

[tex]A=\frac{3\sqrt{3} }{2} a^2\\A=\frac{3\sqrt{3} }{2} (12)^2\\A=\frac{3\sqrt{3} }{2}(144)\\A = 374.12[/tex]

Final answer:

Keith can withdraw money from his account for food for 12 weeks before reaching his minimum account balance requirement of $200.

Explanation:

To determine how many weeks Keith can withdraw money from his account while maintaining a balance of at least $200, we need to perform a simple subtraction and division operation. First, we calculate the amount he needs to leave in the account:
$500 initial balance - $200 desired end balance = $300 available to spend.
Keith withdraws $25 per week for food. To find out how many weeks his money will last, we divide the total amount he can spend by the weekly withdrawal amount:
$300 \/ $25 per week = 12 weeks.
Therefore, Keith can withdraw money for food for 12 weeks before his account balance reaches his minimum requirement of $200.
