Answer:
So,

Let's translate this into mathematical form.

x - y = 9

x + 2y = 27

Elimination by Addition

Divide both sides of the second equation by 2

Add the two equations together

Multiply both sides by

Substitute

15 - y = 9

Subtract 15 from both sides

-y = -6

y = 6

Substitute

15 - 6 = 9

9 = 9 This checks.

15 + 2(6) = 27

Distribute

15 + 12 = 27

27 = 27 This also checks.

S = {(15,6)}

Answer:
a-b=9 ......a=9+b

a+2b=27

(9+b)+2b=27

9+3b=27

3b=27-9

3b=18

b=6

a=9+b=6+9=15

a+2b=27

(9+b)+2b=27

9+3b=27

3b=27-9

3b=18

b=6

a=9+b=6+9=15

Answer:the blue square since it would become -28

Step-by-step explanation:

By arranging the **chairs **in a 13x13 grid, it can achieve an equal number of **rows **and **columns**.

To divide the 169 **chairs **in the gymnasium into an equal amount of rows and columns, we need to find two factors of 169 that are as close to each other as possible.

The **factors **of 169 are 1, 13, and 169.

The closest factors are 13 and 13, which means we can arrange the chairs in 13 **rows **and 13 **columns **to have an equal amount of chairs in each row and column.

Thus, by arranging the chairs in a 13x13 grid, it can achieve an equal number of rows and columns.

Learn more about the **Factorization** here:

#SPJ3

13 rows and columns

13 x 13= 169

13 x 13= 169

815 x 360 = 293,400 gal per second.

293,400 gal ÷ 4 quarts = 73,350 quarts per sec.

I'm fairly certain that's right - someone correct me if I'm mistaken.

293,400 gal ÷ 4 quarts = 73,350 quarts per sec.

I'm fairly certain that's right - someone correct me if I'm mistaken.

The answer would be 0.19

**Answer: about 1.70**

**Step-by-step explanation:**

if V=pi*r^2*h then you'll have 108=pi*r^2*12 so you divide by 12 and pi(3.14)and you square root and your left with your radius

**Answer:**

C. 50

**Step-by-step explanation:**

We are given ΔABC with an altitude BD as shown in the figure.

As it is known that,

*'When an altitude is drawn from a right angle of a triangle, then all the three triangles are congruent.'*

So, we get that ΔABC ≅ ΔABD ≅ CBD.

Since, the triangles are congruent, their corresponding sides and angles will be congruent.

**Moreover, the ratio of the sides will be equal.**

So, we get from ΔABC ≅ ΔABD,

i.e.

i.e.

i.e.

i.e.

i.e. z = 50.

**Hence, the value of z is 50.**
