z=12500

Step-by-step explanation:

Of means multiply and is means equals

85% *z = 106250

Change to decimal form

.85z = 106250

Divide each side by .85

.85z/.85 = 106250 /.85

z=12500

Anita plans to give her husband 3 shirts for his birthday. She narrows the search to 3 shirts from a selection of 17 shirts at D

Lunna [17]

Using the combination formula, it is found that she can select the shirts in 775,200 ways.

The order in which the shirt are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.

Combination formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem:

3 shirts from a set of 17.

Then, 3 shirts from a set of 20.

They are independent, hence, to find the total, we multiply both combinations.

$T = C_{17,3} \times C_{20,3} = \frac{17!}{3!14!} \times \frac{20!}{3!17!} = 680 \times 1140 = 775200$

She can select the shirts in 775,200 ways.

Find the y please use the screen shot

Vikki [24]

Answer:

y = 0.3

Step-by-step explanation:

Solve for y:

$\longrightarrow$ (3.2y - 1.8) - (5.2 y + 3.4) = -5.8

-(5.2y + 3.4) = -5.2y - 3.4:

$\longrightarrow$ 3.2y - 1.8 -5.2y - 3.4 = -5.8

Grouping like terms, 3.2y - 1.8 - 5.2y - 3.4 = (3.2y - 5.2y) + (-1.8 - 3.4):

$\longrightarrow$ (3.2y - 5.2y) + (-1.8 - 3.4) = -5.8

3.2y - 5.2y = -2 y:

$\longrightarrow$ -2y + (-1.8 - 3.4) = -5.8

-1.8 - 3.4 = -5.2:

$\longrightarrow$ -5.2 - 2y = -5.8

Add 5.2` to both sides:

$\longrightarrow$ (5.2 - 5.2) - 2y = 5.2 - 5.8

5.2 - 5.2 = 0:

$\longrightarrow$ -2y = 5.2 - 5.8

5.2 - 5.8 = -0.6:

$\longrightarrow$ -2y = -0.6

Divide both sides of -2y = -0.6 by -2:

$\longrightarrow$ $\sf \dfrac{-2}{-2}y = \dfrac{-0.6}{-2}$

$\sf \dfrac{-2}{-2} = 1:$

$\longrightarrow$ $\sf y = \dfrac{-0.6}{-2}$

$\sf \dfrac{-0.6}{-2} = 0.3:$

$\longrightarrow$ y = 0.3
