The answer is = since each equation equals 32
6•6=36
2•2=4
36-4=32

I JUST WANNA PASS MY SOPHOMORE YEAR BUT I SUCK AT MATH!!!!! PLEASE HELP!!!!!!

Mr. Sanchez's class: 1.65p

Mr. Kelly's class: 1.36j

where p = fruit pies and j = fruit juice

____________________________________________________________

(a) Creating a system of equations

p + j = 79

1.65p + 1.36j = 118.17

are your system of equations

____________________________________________________________

(a) Solving the system of equations for p and j

Solve for p in the first equation. Subtract j from both sides.

p = 79 - j

____________________________________________________________

Plug p into the second equation.

1.65(79 - j) + 1.36j = 118.17

Distribute 1.65 inside the parentheses.

130.35 - 1.65j + 1.36j = 118.17

Combine like terms.

130.35 - 0.29j = 118.17

Subtract 130.35 from both sides.

-0.29j = -12.18

Divide both sides by -0.29.

j = 42

____________________________________________________________

Plug j into the first equation.

p + (42) = 79

Subtract 42 from both sides.

p = 37

____________________________________________________________

(b) To find out how much each class earned

Now plug in p and j into Mr. Sanchez's class and Mr. Kelly's class equations (at the top).

Mr. Sanchez's class: 1.65(37) = 61.05

Mr. Kelly's class: 1.36(42) = 57.12

____________________________________________________________

(c) To see how much more Mr. S's class earned

Subtract 57.12 from 61.05.

61.05 - 57.12 = 3.93

____________________________________________________________

(a)

p + j = 79

1.65p + 1.36j = 118.17

(b)

Mr. Sanchez's class earned more money (61.05 > 57.12).

(c)

Mr. Sanchez's class earned $3.93 more than Mr. Kelly's class.

The ratio of two complementary angles is 7 to 3. what are the angles?
Alex17521 [72]
Complementary angles add up to 90°
----------------------------------------------
Ratio 
----------------------------------------------
7 : 3

----------------------------------------------
Find total parts :
----------------------------------------------
Total parts = 7 + 3 = 10

----------------------------------------------
Find 10 parts :
----------------------------------------------
10 parts = 90

----------------------------------------------
Find 1 part :
----------------------------------------------
1 part = 90 ÷ 10 = 9

----------------------------------------------
Find 7 parts :
----------------------------------------------
7 parts = 9 x 7 = 63

----------------------------------------------
Find 3 parts :
----------------------------------------------
3 parts = 9 x 3 = 27

--------------------------------------------------------------------------------------------
Answer: The ratio of the two angles are 63:27
