Answer:
z = 5
Step-by-step explanation:
m = ∆y/∆x = y₂-y₁/x₂-x₁
0 = y₂-y₁/x₂-x₁ = 5 - z / -7 - 9 = 5 - z / -16 →
5 - z / -16 = 0 → 5 - z / -16 × -16 = 0 × -16 → 5 - z = 0 →
5 - z - 5 = 0 - 5 → -z = -5 → z = 5
Answer:
60
Step-by-step explanation:
Steps to solve "54 is 90 percent of what number?"
We have, 90% × x = 54
or,
90/100 × x = 54
Multiplying both sides by 100 and dividing both sides by 90,
we have x = 54 × 100/90
x = 60
If you are using a calculator, simply enter 54×100÷90, which will give you the answer.
