4). x/5 =8
x = 40
5). 2x/3 = 12
2x = 36
x = 36/2 = 18
6). x + 26 =12
x = 12 - 26 = -14
7). 8x + 1 = -23
8x = -23 -1
8x = -24
x = -24/8 = -3
8). 2x + 5 =15
2x = 15 - 5
2x = 10
x = 10/2 = 5
9). 3x - 1 = -29
3x = -29 + 1
3x = -28
x = -28/3 Or 9.33
10). 8x - 12 = 53
8x = 53 + 12
8x = 65
x = 65/8 Or 8.12
11). 4x + 7 = 25
4x = 25 - 7
4x = 18
x =18/4 = 9/2 Or 4.5
Answer:
The unit rate is 3 $/ft
Step-by-step explanation:
Let
x ----> the number of feet
y ----> represent the cost of a piece of pipe
we have
y=3x
Remember that
A connection between two factors, x, and y, speak to a relative variety on the off chance that it tends to be communicated in the structure y/x=k or y=kx
In a corresponding relationship the steady of proportionality k is equivalent to the incline m of the line and the line goes through the source
In this problem we have a proportional relationship
The unit rate is a similar that the slant of the straight capacity or the steady of proportionality k
so
m=k=3 $/ft
therefore
The unit rate is 3 $/ft

Answer:
Isosceles obtuse Triangle
To find the future value, you would multiply the starting value from year one by 1+ the percent of increase per year raised to the number of years you want.,
The starting value of the house would be the value from year one: 212,566.20
The equation would then be: f(t) = 212,566.20(1.05)t
