<span>-3(5+8r)=33-8r
-15 - 24r = 33 - 8r
-15 - 33 = - 8r + 24r
-48 = 16r
-48/16 = r
-3 = r
r = -3</span>

Answer: x = 45</h3>
Work Shown:
x+x+90 = 180 .... all three angles of a triangle add to 180
2x+90 = 180
2x = 180-90
2x = 90
x = 90/2
x = 45
This is a 45-45-90 right triangle. We also consider it an isosceles right triangle because the base angles (45) are equal.
I just took the test the correct answer is 285.74 square centimeters
Four $5 bills and two $1 bills
In total it’s six bills
5(4)=20 and 1(2)=2
20+2=22
Given The equation -2x(-2.8)=24, we are trying to find the value of X.
The first step is to devide both sides by 2
·-x(-2.8)=12
The next step would be to distribute.
·2.8x=12
Next we devide both Sides By 2.8 to get our final answer
·X=4.28
Although your choice answers are unclear, the answer is X=4.
