Answer:
hope this helps! :)
Step-by-step explanation:
4x=36
divide both sides of the equation by 4
4x / 4 = 36 / 4
Any expression divided by itself equals 1
x= 36 / 4
Calculate the quotient
36/4 = 9
<u>x=9</u>
Step-by-step explanation:
They are all polygons with four sides.
The sum of the measures of their interior angles is 360°.
The measurement of angle a plus 120 must equal to 180 ( as angles on a straight line must equal to 180)
So measurement of angle a is 60 degrees
Measurement of angle b plus 60 plus 60 must equal to 180
So measurement of angle b is 60
Answer:
Step-by-step explanation:
- Total serves = 75
- Serves in = 4/5 of total
<u>Number of serves in:</u>
Correct choice is D
The equations we get are
l = 6 + 2w (We get this from "The length of the rectangle is 6 more than 2 times the width.")
and
2l + 2w = 140 (We get this from the perimeter. Two times the length plus two times the width equals the perimeter of a quadrilateral.)
The first equation can be written as
l - 2w = 6
So now we have
2l + 2w = 140
l - 2w = 6
____________
Add the two equations.
We get 3l = 146
Divide by 3 on both sides.
l =
48
Your answer is
48
