Answer & Step-by-step explanation:

Add 1 to both sides.

Multiply both sides by 4.

Take the square root of both sides.


Subtract 5 from both sides.

Answer: 8 7/10 hours
whole part = 8
fractional part = 7/10
========================================================
Work Shown:
x = number of hours driving
(5/6)x = total number of gallons of gas used
(5/6)x = 7 & 1/4
(5/6)x = 7 + 1/4
(5/6)x = 28/4 + 1/4
(5/6)x = 29/4
x = (29/4)*(6/5)
x = (29*6)/(4*5)
x = 174/20
x = 87/10
x = (80+7)/10
x = 80/10 + 7/10
x = 8 + 7/10
x = 8 & 7/10
This is the same as writing 8 7/10
Amy drove 8 full hours, plus an additional 7/10 of an hour.
That mixed number converts to the decimal value 8.7
Find the area of the triangle on top
A=(.5)(Base)(Height)
A=(.5)(15)(9)
A=67.5
In the rhombus below you can move the corner triangle to the other side to transform it into a rectangle with a sides of 7 and 15. so lets find the area of this rectangle
A=L*W
A=15*7
A=105
now combine the two areas
67.5+105
172.5
so answer "C"
Answer:

Step-by-step explanation:
Given:

Number line is from range -2 to 2 with all increment of ±
on both sides.
Step 1: First we will solve the equation we will get;

Step 2: Now we will try to make the denominator common so we will get;

Step 3: Now from the number line when we subtract 
from
we get number of spaces left are - 7
Hence now it will become:

Hence the final Answer is
