Answer:
The answer is D
x = 4
y = -2
z = 3
Step-by-step explanation:
Plug in the values of x and z into the first equation, and see that D is the only choice that is correct.
Part A: c for cost. c=0.31m+0.5
0.31m is the cost per minute. 0.5 is cost per call.
Part B: 0.31m+0.5=5.15 to solve we must rearrange.
subtract 0.5 from each side giving us 0.31m=4.85
divide by 0.31 giving us m=15.65
Answer:
commutative property
Step-by-step explanation:
It's basically just changing the order of the equation.
Answer:
20 units
Step-by-step explanation:
The 3 part of the ratio refers to 15 units
Divide 15 by 3 to find the value of one part of the ratio
15 ÷ 3 = 5 ← value of 1 part of the ratio, thus
4 parts = 4 × 5 = 20 units ← perimeter of larger figure
