What value of z makes the statement true?

1 answer:

4 0

-(z + (-17)) = 12 + 17

-(z - 17) = 12 + 17

Distribute -1:

-z + 17 = 12 + 17

Subtract 17 to both sides:

-z = 12

Multiply -1 to both sides:

z = -12

Jim sells candy bars to his family and friends as a fundraiser. The plain chocolate bars costs $1.50, and the king size chocolat

Zarrin [17]

Answer:

38 plain chocolate bars and 17 king-size chocolate bars.

Step-by-step explanation:

Let's define the variables:

P = number of plain chocolate bars sold

K = number of king chocolate bars sold

We know that each plain one costs $1.50, and each king one costs $2.25, then the total revenue is:

P*$1.50 + K*$2.25

Now we know that Jim sells a total of 55 candy bars, then:

P + K = 55

And we know that the total revenue is $95.25, then:

P*$1.50 + K*$2.25 = $95.25

Then we have the system of equations:

P + K = 55

P*$1.50 + K*$2.25 = $95.25

To solve this we need to isolate one of the variables in one of the equations, I will isolate P in the first equation to get:

P = 55 - K

Now we can replace is on the second one to get:

(55 - K)*$1.50 + K*$2.25 = $95.25

Now we can solve this for K

$82.50 - K*$1.50 + K*$2.25 = $95.25

K*($2.25 - $1.50) = $95.25 - $82.50 = $12.75

K*$0.75 = $12.75

K = $12.75/$0.75 = 17

This means that Jim sold 17 king-size chocolate bars.

Now we can replace this in the equation:

P + K = 55

P + 17 = 55

P = 55 - 17 =38

P = 38

Jim sold 38 plain chocolate bars.

Answer:

$\displaystyle \frac{a^2 }{b^2}=\frac{4}{9}$

$\displaystyle \frac{a}{b}=\frac{2}{3}$

$\displaystyle \frac{a^3}{b^3}=\frac{8}{27}$

Step-by-step explanation:

<u>Ratios and Proportions </u>

The ratio between two numbers x and y is defined as x/y. It measures how many times y is contained in x. For example 12/8 = 1.5 means 12 is 1.5 times 8.

We have two key sets of data: the ratio between the surface areas of the cylinders and the fact that the radius and heights of the cylinders come in the same proportion.

First, we can easily compute the ratio of the surface areas

$\displaystyle \frac{Area_1}{Area_2}=\frac{8\pi \ in^2 }{18\pi \ in^2}=\frac{4}{9}$

It gives us the relation

$\displaystyle \frac{a^2 }{b^2}=\frac{4}{9}$

Computing the square root

$\displaystyle \frac{a}{b}=\frac{2}{3}$

Computing the cube

$\displaystyle \frac{a^3}{b^3}=\frac{8}{27}$
