5x - 3 = 7
<em><u>Add 3 to both sides.</u></em>
5x = 10
<em><u>Divide both sides by 5.</u></em>
x = 2
The value of x is 2.
Angle 1. Because angle 4 and 1 are vertical angles and vertical angles are congruent.
Answer:
400
Step-by-step explanation:
325 + 75
Answer:
B) 60.21 ft²
Step-by-step explanation:
Area of a triangle = 1/2bh
You can‘t used mixed measurements (feet and inches), so you have to convert each length to inches
8’6”=102’
14’2”=170’
Now find the area
1/2 x 102 x 170 = 8670 in²
This is one of the answers, but the quetion asks how many quart feet you need.
So, convert it back to feet.
8670 x 0.06944444444 = 60.2083333
(You could also have converted the two lengths to feet. 8’6” = 8.5 ft. 14’2” = 14.16666666. This way would probably have been faster.
1/2 x 8.5 x 14.166666 = 60.20833333)
