Jason's business computers need servicing. The expression 81x + 108 represents a contractor's total charges in dollars for fixin

kolbaska11 [484]

Answer:

2 hours

Step-by-step explanation:

Given

$Contractor: 81x + 108$

$Electronic\ Store: 103x + 64$

Required

Determine the hours when the charges are the same

To do this, we simply equate both expressions:

$Contractor = Electronic\ Store$

$81x + 108 = 103x + 64$

Collect Like Terms

$81x - 103x = 64 - 108$

$-22x = -44$

Divide both sides by -22

$x =2$

What value of x would make Bl parallel to RA?

igomit [66]

Given:

Bl parallel to RA.

To find:

The value of x.

Solution:

In triangle ATR and ITB,

$\angle ATR\cong \angle ITB$ [Common angles]

$\angle ART\cong \angle IBT$ [Corresponding angle]

$\triangle ATR\sim \triangle ITB$ [AA property of similarity]

We know that the corresponding sides of a similar triangle are proportional. So,

$\dfrac{AT}{IT}=\dfrac{AR}{IB}$

$\dfrac{x}{x+8}=\dfrac{12}{18}$

$\dfrac{x}{x+8}=\dfrac{2}{3}$

On cross multiplication, we get

$3(x)=2(x+8)$

$3x=2x+16$

$3x-2x=16$

$x=16$

Therefore, the correct option is C.
