Answer:
20
Step-by-step explanation:
If the two triangles are similar, then corresponding sides must share a constant ratio. This means that:

Let's use the second ratio:

Multiply both sides by 12:

Answer:
The value of x will be:
Step-by-step explanation:
Given the equation

Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.

simplifying the equation by subtracting 14 from the L.H.S

Subtracting 15 from both sides


combining the like terms


dividing both sides of the equation by 5


Therefore, the value of x will be:
The answer is A $ 167
I=pr^t-p
I=500(104.2/100)^7-500
I=500(1.042^7-1)
I=$167.00 to nearest dollar
