Answer:
The answer is A. 0.1x + 18.2
Step-by-step explanation:
We have to simplify the expression
We will use distributive Property of Multiplication with respect to Addition and Subtraction
⇒3×(2.7 x +5) -2 ×(4 x -1.6)
=3×2.7 x +3×5-2×4 x-2×(-1.6)
=8.1 x +15 -8 x+3.2
=(8.1 x- 8 x)+15+3.2-----Adding and Subtracting like terms
= 0.1 x +18.2
Option A
The answer to the question
Step-by-step explanation:
L= W+5
P= 9W
P= 2L+ 2W
9W= 2(W+5) + 2W
9W= 2W +10 +2W
9W = 4W +10
5W = 10
W = 2
L=7
P= 9(2)
P= 18
A= LW
A= 7 x 2
A= 14
Answer:

Step-by-step explanation:
Let
x -----> the number of hours
y ----> the total cost to rent a bike in dollars
we know that
The equation of the line in slope intercept form is equal to

where
m is the slope or the unit rate of the linear equation
b is the y-intercept or the initial value
In this problem we have
The unit rate or slope is equal to

The y-intercept (value of y when the value of x is equal to zero) is equal to
----> (fee charge)
substitute the values

I think that the answer could be D
