Answer:
x = -8
Step-by-step explanation:
Given: 5(x+4)+52=-4x
Distributive Property: 5x+20+52=-4x
Combine like terms: 5x+72=-4x
Subtract 5x on both sides: 72=-9x
Divide both sides by -9: -8=x
Flip the equation around: x=-8
Therefore, x=-8
Given:
The equation is:
To find:
The solution for the given equation.
Solution:
We have,
It can be written as:
Taking square root on both sides, we get
[Radius cannot be negative]
Therefore, the value of r is about 6.36 cm.
First find out how much he makes in 8 hours (9x8=72). Then subtract 72 from 155 (155-72=83). Then divide 83 by 6 (83/6=13.8333). Since 83 is not evenly divisible by 6, and since he can't deliver .8333 of a delivery, we would round up, giving us 14). Ben would need to make 14 deliveries in 8 hours to make more than $155 :) Hope this helps you :)
