A culture of 1.75×10^18 bacteria is in petri dish A. A culture of 6.25×10^15 bacteria is in petri dish B.How many times greater is the number of bacteria in petri dish A than petri dish B?Enter your answer, in standard notation, in the box.

Let's assume

number of months =x

A high definition radio station charges $200 per year

so, we get point as (0,200)

Assume

f(x) is the total amount of charges in a year

we can see that this is linear relationship

so, we can use formula

[tex]f(x)=mx+b[/tex]

in addition to $50 per month for the first 3 months to receive its broadcast

so, m=50

we can plug it

[tex]f(x)=50x+b[/tex]

we can use point as (0,200)

[tex]200=50*0+b[/tex]

[tex]b=200[/tex]

now, we can plug it back

and we get

[tex]f(x)=50x+200[/tex]...............Answer

x = [tex]\frac{n-p}{m}[/tex]

isolate x by dividing both sides by m

x = [tex]\frac{n-p}{m}[/tex]

The expression you would use is 15 + .65x = 80. If you solve for x, Beth swam 100 laps.

Hope its correct and good luck :)

Answer: There are 4 adults. Two males. 16 children.

Step-by-step explanation:

2 x 2 = 4

4 adults

4 x 5 = 20

20 + 4 = 24

24 = 24

Answer:

Exact same way:

4 adults,

2 males & 2 females,

and 16 children

Step-by-step explanation:

Exactly as his!

x + y = 20

30x + 25y = 550

Using the first equation, we can find a temporary value of x.

x = 20 - y

Now that we have a value of x, we can plug it into the second equation to find the exact value of y.

30x + 25y = 550

30(20 - y) + 25y = 550

Distributive property.

600 - 30y + 25y = 550

Combine like terms.

600 - 5y = 550

Add 5y to both sides.

600 = 550 + 5y

Subtract 550 from both sides.

50 = 5y

Divide both sides by 5.

y = 10.

Now we can plug the value of y into the original equation to find the value of x.

10 + x = 20

Subtract 10 from both sides.

x = 10

The value of x is equal to 10, and the value of y is also equal to 10.

solution is (x, y ) = (10, 10)

given

x + y = 20 → (1)

30x + 25y = 550 → (2)

from (1) y = 20 - x → (3)

substitute y = 20 - x in (2)

30x + 25(20 - x) = 550

30x + 500 - 25x = 550

5x + 500 = 550 ( subtract 500 from both sides )

5x = 50 ( divide both sides by 5 )

x = [tex]\frac{50}{5}[/tex] = 10

substitute x = 10 in (3) : y = 20 - 10 = 10

thus x = 10, y = 10 is the solution

Since it is true that 9=9, the answer x=2 works.

As equations get more complex it is important to use properties of equality to isolate the variable and solve the equation.

Here are the properties of equality you need to isolate terms and solve equations.

The Subtraction Property of Equality is used when you have an equation with addition in it. It states that you can subtract the same quantity from both sides of the equation without changing the equality.

The Addition Property of Equality is used when you have an equation with subtraction in it. It states that you can add the same quantity to both sides of the equation without changing the equality.

The Division Property of Equality is used when you have an equation with a variable multiplied by a number. It states that you can divide both sides of an equation by the same quantity (as long as that quantity is not equal to zero) without changing the equality.

The Multiplication Property of Equality is used when you have an equation with a variable divided by a number. It states that you can multiply both sides of an equation by the same quantity without changing the equality.

Let’s look at an example and use properties of equality to isolate the variable and solve the equation.

Answer:

-18

Step-by-step explanation:

The tall sticks around n+5 are absolute value signs. Basically, all you need to do is work out what the answer to the problem is inside the signs, then make whatever the answer is positive, then multiply by -9.

-7 + 5 = -2 (that turns into 2)

-9 x 2 = -18

Answer:

We should use 4 pounds of $6 coffee and 2 pounds of $3 coffee for the blend.

Step-by-step explanation:

The blend should,

Cost = $5

Weigh = 6 pounds.

Lets take the weight of $6 coffee as [tex]x[/tex] pounds

And lets take the weight of $3 coffee as [tex]y[/tex] pounds.

Lets write an equation for the weight of the blend,

[tex]x+y=6[/tex] <---------- 1st equation.

[tex]\frac{6x+3y}{x+y} =5[/tex]

=[tex]6x+3y=5x+5y[/tex]

=[tex]x=2y[/tex] <---------- 2nd equation

We can substitute to x in 1st equation from 2nd equation,

⇒[tex]2y+y=6[/tex]

=[tex]2y+y=6[/tex]

=[tex]3y=6[/tex]

=[tex]y=2[/tex]

We can substitute y value to 2nd equation to find x,

⇒[tex]x=2y[/tex]

=[tex]x=2*2[/tex]=[tex]x=4[/tex]

Therefore, we should use 4 pounds of $6 coffee and 2 pounds of $3 coffee for the blend.

Answer:

3.3x − 6.6 = 2.7x   ⇔   0.6x = 6.6

B is correct

Step-by-step explanation:

The equation 3.3x − 6.6 = 2.7x can be transformed to another form.

Given

3.3x − 6.6 = 2.7x

Move all variable same side. using subtraction property of equality

subtract 2.7x both sides

3.3x -2.7x − 6.6 = 0

         0.6x - 6.6 = 0

Addition property of equality

   0.6x = 6.6

Hence, The equivalent equation is 0.6x = 6.6

Answer:

Step-by-step explanation:

3.3x - 2.7x = 6.6

0.6x = 6.6

answer is B

answer is also 11

Remark

One of the ways you could solve this is to go to a place like Desmos and graph it for yourself. Then at least you would know what the answer looked like. Another way is to solve for the x value by equating the equations since the y has to be the same. We'll do both.

Solve For X

(2/3)x + 1 = -(2/3)x - 1    Add 1 to both sides

(2/3)x + 1 + 1 = - 2/3x    Subtract (2/3x) from both sides.

2 = (-2/3)x - (2/3)x

Show the graph and comment

Notice that there is only one graph given that has a value of x = - 3/2 Normally you are not that lucky. Thanks for putting the graphs in. We are usually not that lucky and have to guess at the answer if it is a graph.

2 = - 4/3x                      Multiply both sides by 3

2 * 3 = - 4x    

6 = - 4x                          Divide by - 4

6/-4  = x                        Reduce

-3/2  = x

Remark

The x value is wrong for the one on the left.  It is also wrong for the third one from the left.  And the last graph is also incorrect.     Only the second from the left gives the right answer.                                      

I believe it is 30% because you can divide 200 in half to get it out of 100, and then divide 60 in half to make it even! (i’m sorry if this doesn’t make sense)

Final answer:

To calculate what percent of people like rap out of 200 who came to a fundraiser, divide the 60 people who like rap by 200 and multiply by 100, resulting in 30% of people liking rap.

Explanation:

The question asks us to calculate what percent of people like rap out of 200 kids who came to a fundraiser. To find the percentage of people who like rap, we use the basic formula for finding percentages: (Part / Whole) × 100. Here, the 'Part' is the number of people who like rap, and the 'Whole' is the total number of kids who came to the fundraiser.

Given:
Part (people who like rap) = 60
Whole (total kids at the fundraiser) = 200

Using the formula, we calculate the percentage as follows:
(60 / 200) × 100 = 0.3 × 100 = 30%.

Therefore, 30% of the people at the fundraiser like rap.

The measures of both angles are 24° and 66°.

Given:

m<K = 3x + 3

m<L = 10x-4

Note:

Complementary angles are angles whose sum equals 90 degrees.

Therefore:

[tex]m \angle K + m \angle L = 90^{o}[/tex]

Substitute

[tex](3x+3) + (10x-4) = 90[/tex]

Solve for x

[tex]3x+3 + 10x-4 = 90\\[/tex]

Add like terms

[tex]13x-1 = 90\\[/tex]

Add 1 to both sides

[tex]13x = 90 + 1\\13x = 91[/tex]

Divide both sides by 13

[tex]x= 7[/tex]

Substitute the value of x in each of the expressions of the two given complementary angles.

[tex]m\angle K = 3(7) + 3 = 21 + 3\\m\angle K = 24^{o}[/tex]

[tex]m\angle L = 10(7) - 4 = 70 - 4 \\m\angle L = 66^{o}[/tex]

Therefore, the measures of both complementary angles are: 24° and 66°.

-12(x+2)=6(-4-2x)+4x

-12x-24=-24-12x+4x

x=0

x is equal to zero. Distribute The -12 to x and 2. Then distribute the 6 to -4 and -2.

combining like terms gives you -12-24=24-8x

next you should get x by itself.  that gives you 0 as the final answer

Obviously, if he were to only maximize his income he would put all money on the higher interest. But to reduce the risk he will balance the investment. He will put a fraction a (between 0 and 1) of the 710000 on 1% and the rest (1-a) on the 4.5%.  Both interests together must then satisfy to add up to 18000.

So written as an equation:
