Question 3 options:
Grace [21]

Answer:

90

Step-by-step explanation:

Given: Measure of one side of equilateral triangle = 9+3x

Measure of another side of equilateral triangle = 5x-5

In equilateral triangle all three sides are equal in length.Therefore,

5x-5 =9+3x

5x-3x=9+5

2x=14

x=\frac{14}{2} =7

On substituting the value of x in side of equilateral triangle,

One side of equilateral triangle = 5x-5=\left (5(7)-5 \right )=(35-5)=30

Perimeter of equilateral triangle = 3 ( length of one side) ........( given)

perimeter of equilateral triangle = 3\times30 = 90.

How I simplify this real life expression and show unit analysis?
Anton [14]

The value of the real life expression is, simple interest = $12.5

<h3>How to simplify this real life expression and show unit analysis?</h3>

The real life expression is given as:

simple interest = ($100) (0.05/year) (2.5 years

Divide 1 year by 1 year

simple interest = ($100) (0.05) (2.5)

Rewrite the equation as a product of factors

simple interest = ($100) * (0.05)*  (2.5)

Evaluate the product of 0.05 and 2.5

simple interest = ($100) * 0.125

Evaluate the product of $100 and 0.125

simple interest = $12.5

Hence, the value of the real life expression is, simple interest = $12.5
