Answer:
2x+30
Step-by-step explanation:
The formula for perimeter is
P = 2(l+w)
= 2(2/3 x+10 + 1/3 x+5)
= 2(2/3 x + 1/3 x+10+5)
= 2 (x+15)
Distribute
2x+30
The answer to this question will be B
Using a proportional relationship, we have that:
- a) The constant of proportionality is of 0.625, hence the equation is:
.
- b) The distance of two cities that are 5 miles apart is of 8 kilometers.
- c) When they are 200 kilometers apart, we have that the distance in miles is of
.
<h3>What is a proportional relationship?</h3>
- A <em>proportional relationship</em> is a function in which the <u>output variable is given by the input variable multiplied by a constant of proportionality</u>, that is:.

- In which k is the constant of proportionality.
Item a:
From the graph, when x = 8, y = 5, hence:

Answer:
Answer:
a. ----> $10
b. ----> $110
Step-by-step explanation:
Step-by-step explanation:
principle ( p ) = $100
time ( t ) = 10 years
rate ( r ) = 11%
simple interest = (p × r × t)÷ 100
= ( $100 × 11 × 10 )÷ 100
= 11000 ÷ 100
= $110
interest = simple interest - principle
interest = $110 - $100
= $10
