-6-3= -9
-5-5= -10
7-7=0
-75-(-75)= 0

You and three friends are eating a pizza with 12 pieces. Each person eats the same number of pieces. Let x represent the number
Setler [38]

Answer:

C. 4x = 12

Step-by-step explanation:

You and three friends= you + 3 friends=4 people

Pizza= 12 pieces

Each person eats equal pieces of pizza

x= number of pieces each person ate

Equation

4x=12

Divide both sides by 4

x=12/4

=3

x=3

Therefore, each person ate 3 pieces of pizza each

Check:

4x=12

4(3)=12

12=12

KengaRu [80]

Answer:

6 : 23

Step-by-step explanation:

a : b = 3 : 4 ....(given)\\  \\ let \: a = 3x \\ b = 4x \\  \\ (6a - 3b) : (5a + 2b) \\  \\  =  \frac{(6a - 3b)}{(5a + 2b)}  \\  \\  = \frac{6(3x) - 3(4x)}{5(3x) + 2(4x)} \\  \\  =  \frac{18x- 12x}{15x+ 8x} \\  \\  = \frac{6x}{23x} \\  \\  =  \frac{6}{23}  \\  \\ (6a - 3b) : (5a + 2b) = 6  : 23
