4.2x - 1.4y = 2.1 |multiply both sides by 10
42x - 14y = 21 |subtract 42x from both sides
-14y = 21 - 42x |change signs
14y = 42x - 21 |divide both sides by 14
y = 3x - 1.5
Answer:
see below
Step-by-step explanation:
1. 2m = 24
Divide each side by 2
2m/2 = 24/2
m = 12
2. y – 9 = 30
Add 9 to each side
y-9+9 = 30+9
y = 39
3. X/4 = 12
Multiply each side by 4
x/4*4 = 12*4
x = 48
4. k + 12.5 = 30
Subtract 12.5 from each side
k+12.5-12.5 = 30-12.5
k =17.5
5. 3r = 15.3
Divide by 3
3r/3 = 15.3/3
r =5.1
3/4x+3-2x=-1/4x+1/2x+5
3x+12-8x=-x+2x+20
-5x+12=x+20
-5x-x=20-12
-6x=8
-6x/-6=8/-6
X=8/-6
X=-4/3

Answer:
D
Step-by-step explanation:
Just divide the 2 rates, so for Candice it would be 11.98 / 2 so 5.99 per pizza.
For Peter just pick any rate, like 23.96 / 4, which would also be 5.99 per pizza.
