Jim has $700 in savings at the beginning of Summer he wants to have at least $300 in savings when he goes to buy back to school clothes he withdraws $25 per week for spending money how many weekends can he withdraw his amount and still have the amount he wants to buy back to school clothes

Let x be the number of rows.

If the number of rows is 7 less than the number of seats in each row, then the number of seats in a row is x+7. The total number of seats is

x·(x+7).

You know that a theater can seat 120 people, then

x·(x+7)=120.

Solve it:

[tex]x^2+7x-120=0,\\\\D=7^2-4\cdot (-120)=49+480=529,\ \sqrt{D}=23,\\\\x_1=\dfrac{-7+23}{2}=8, \ x_2=\dfrac{-7-23}{2}=-15.[/tex]

The number of rows must be positive, then x=8.

Answer: there are 8 rows with 15 seats at each.

4 x 9 = 36

9 x 4 = 36

36/9 = 4

36/4 = 9

The answer is 24d because you have to simplify d_c first then you have 24c x  d_c  and then c cancels itself out so the answer is 24d.

Answer:

D. 300/3 = 100

Step-by-step explanation:

He needs to divide the number by 3 since he is placing 3 erasers in each bag. He needs to divide 280 by 3. 280 divided by 3 is not a choice. The closest choice is 300/3, so that is the correct answer.

x - y = 15

2x + 8 = 3y - 4

Using the first equation, we can get an approximate value for x.

x = 15 + y

Now that we have a value for x, we can replace it in the second equation to find the value of y.

2(15 + y) +  8 = 3y - 4

Distributive property.

30 + 2y + 8 = 3y - 4

Combine like terms.

38 + 2y = 3y - 4

Subtract 2y from both sides.

38 = y - 4

Add 4 to both sides.

y = 42

Now that we have the value of y, we can find the value of x.

x - 42 = 15

Add 42 to both sides.

x = 57

f(3) = 2x² - 3x + 1

2(3)² - 3(3) + 1

18 - 9 + 1

F(3) = 10

f(2) = 2(2)² - 3(2) + 1

8 - 6 + 1

f(2) = 3

f(3) - f(2)

10 - 3

f(3) - f(2) = 7 because you find f(3) = 10, and f(2) = 3, and plug in the answer you found. This gives you 10 - 3, which is 7.

The value of f(3) - f(2) is 7 if the function f(x) = 2x² - 3x + 1 the correct answer is option B: 7.

To find f(3) and f(2), we need to plug the respective values of x into the given function f(x) = 2x² - 3x + 1 and then subtract the results.

f(3):

f(3) = 2(3)² - 3(3) + 1

f(3) = 2(9) - 9 + 1

f(3) = 18 - 9 + 1

f(3) = 10

f(2):

f(2) = 2(2)² - 3(2) + 1

f(2) = 2(4) - 6 + 1

f(2) = 8 - 6 + 1

f(2) = 3

Now, let's find f(3) - f(2):

f(3) - f(2) = 10 - 3 = 7

So, the value of f(3) - f(2) is 7.

The correct answer is option B: 7.

We have been given that

3x - y = 3 and

y = 2x + 2

Substitute y = 2x + 2 in the first equation, we get,

3x - (2x + 2) = 3

3x - 2x - 2 = 3

x - 2 = 3

x = 5

y = 2x + 2

= 2(5) + 2

3/8 is the right answer to that question

The answer to 3/4*1/2 is

0.375

your correct answer is 4.27 so 4.27/22

Answer,

Explanation,

Step 1: Simplify both sides of the equation

24 − 3x = −27

24 + −3x = −27

−3x + 24 = −27

Step 2: Subtract 24 from both sides.

−3x + 24 − 24 = −27 − 24

−3x = −51

Step 3: Divide both sides by -3.

-3x/-3 = -51/-3

The question presents a basic algebraic problem. We translate the words into a mathematical equation, 4x + 7 = 5. After some simple manipulations (subtracting 7 from both sides and dividing the result by 4), we find that the value of x is -0.5.

The question presents a typical example of a simple equation in Mathematics. The first step in solving this problem involves interpretation. The statement 'The sum of 4 times a number and 7 is equal to 5' can be translated into this equation: 4x + 7 = 5. To obtain the value of x, we need to isolate it on one side of the equation.

We can proceed by subtracting 7 from both sides
to achieve 4x = -2. Finally, we divide both sides of the equation by 4 to obtain x = -0.5. Thus, the number in question is -0.5.

You have to see if they are all moving up at a constant rate. You can check this by subtracting $17.40 from $21.75. It is $4.35. Then multiply $4.35 by 46. If it is not equal to $200.10, then it is not a proportional relationship. When you multiply it, you actually do get $200.1, which is equal to $200.10. So this is a proportional relationship.

Solution :

We have to find all the possible solutions for the inequality [tex]2x+7<3x-5[/tex].

The given inequality can be solved as,

Subtracting 7 from both side , we get

[tex]2x+7-7 < 3x-5-7\\\\\Rightarrow 2x<3x-12[/tex]

Now, Subtracting 3x from both side, we get

[tex]2x-3x<3x-12-3x\\\Rightarrow -x <-12\\[/tex]

As we here we can see that both sides have similar sign, so we can cancel them out.

[tex]\Rightarrow x < 12[/tex]

Hence, the possible solution of the inequality  [tex]2x+7<3x-5[/tex] is [tex]x< 12[/tex]

The speed of the slower jets and faster jets are 624 mi / Hr and 684 mi/hr respectively.

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.

Let the speed of a slower jet be represented as 'x'

Now Given:

one jet travels 60 mph slower than the other.

Hence Speed of a faster jet will be = x  +   60

Distance = 7848  miles

Time = 6 hrs

Now we know that;

Distance is equal to the product of speed and time.

Framing in the equation we get;

Distance = (Speed of Faster Jet + Speed of Slower jet) × Time.

Substituting the given values we get;

7848  =  ( x  +  x  +  60  )  6

7848  =  12x  +  360

x  =  624

Speed of slower jet = 624 miles/hr

Speed of faster jet = 624  +  60  =  684 miles/hr

Hence Speed of the Faster jet is 684 miles/hr and the speed of the slower jet is 624 miles/hr.

Answer:  A

Step-by-step explanation:

Let us first observe behavior in only quadrant 1 .

On x-axis one small box represent one year.

On y-axis one small box represent  one dollar.

If we see the 1 year on x-axis its corresponding value of dollar on y -axis is in mid of 4 dollars and 5 dollars.

Now if we see the 2nd year on x-axis its corresponding value of dollar on y-axis is at 6 dollars .

It concluded that after each year 0.5 dollars per pound increases.

We can see the same behavior throughout the straight line.
