Solve for x..................
Yanka [14]

Answer:

x = 4

Step-by-step explanation:

(5x+131)° and (5x+19)° are supplementary. Therefore, (5x+19)° + (5x+131)° equals to 180°.

Knowing that, we can do the following:

  • (5x+19) + (5x+131) = 180
  • 5x + 19 + 5x + 131 = 180
  • 10x + 140 = 180
  • 10x = 40
  • <em>x = 4</em>

A landscaping company charges $50 per cubic yard of mulch plus a delivery charge of $24. Find a
Zigmanuir [339]

Answer: c(x) = $50*x + $24

Step-by-step explanation:

First, this situation can be modeled with a linear equation like:

c(x) = s*x + b

where c is the cost, s is the slope, x is the number of cubic yards of mulch bought, and b is the y-intercept ( a constant that no depends on the number x)

Then we know that:

The company charges $50 per cubic yard, so the slope is $50

A delivery charge of $24, this delivery charge does not depend on x, so this is the y-intercept.

Then our equation is:

c(x) = $50*x + $24

This is:

"The cost of buying x cubic yards of mulch"
