Eliminate one of the variables..

2x + 2y = 28

2x = -2y + 28

8x - 2y= 22

8x = 2y + 22
x = 0.25y + 2.75

combine equations...

-y +14 = 0.25y + 2.75

solve for the variable..

-y - 0.25y = 2.75 - 14
-1.25y = -11.25
y = 9

replace y with 9 in previous equation..

x = -y + 14
x = -9 + 14
x = 5

so y = 9 and x = 5

I hope I did that right good luck!

Answer:

8. $356,250

9. 50,000 Birds

Step-by-step explanation:

8. $75,000*12.5%=$9375

30*$9375=281250

$75,000+$281,250=$356,250

9. 200,000*0.75%=1500

100*1500=150,000

One wintry week a ski town got 5 1/3 inches of snow. On monday the town got 2 3/4 inches; on tuesday it got 1 1/2 times as much;

m_a_m_a [10]

Answer: The amount of snow the town get the rest of the week is given by

$\frac{5}{24}$

Step-by-step explanation:

$\text{ Total inches of snow town got in a week }=5\frac{1}{3}=\frac{16}{3}$

$\text{ Amount of snow it is receiving on Monday}=2\frac{3}{4}=\frac{11}{4}\text{ inches }$

$\text{Amount of snow it is receiving on Tuesday}=1\frac{1}{2}=\frac{3}{2}\text{ inches }$

$\text{Amount of snow it is receiving on Wednesday}=\frac{7}{8}\text{ inches }$

$\text{Amount it is receiving in remaining week is given by}$

$\frac{16}{3}-(\frac{11}{4}+\frac{3}{2}+\frac{7}{8})\\\\=\frac{16}{3}-\frac{22+12+7}{8}\\\\=\frac{16}{3}-\frac{41}{8}\\\\=\frac{128-125}{8}\\\\=\frac{5}{24}\text{ inches }$

So, the amount of snow the town get the rest of the week is given by

$\frac{5}{24}\text{ inches }$
