-4r-11=4r+21
Move 4r to the other side
Sign changes from +4r to -4r
-4r-4r-11=4r-4r+21
-4r-4r-11=21
-8r-11=21
Move -11 to the other side
Sign changes from -11 to +11
-8r-11+11=21+11
-8r=21+11
-8r=32
Divide both sides by -8
-8r/-8=32/-8
Answer: r=-4
No because 0x14 would be 0 BUT it is still multiplication.
Nine million, four hundred thousand, twenty three9
Answer:
- 35
Step-by-step explanation:
2(x - 7) = 3(x+7)
2x - 14 = 3x + 21
- 21 - 14 = 3x - 2x
x = - 35
Rechecking :
2(-35 - 7) = 3 (-35 +7)
- 84 = - 84
I hope im right!!!
Answer:
z=44
Step-by-step explanation:
One way to go about this with the given angles is to use the alternate interior angles theorem to find the full measure of ∠C and ∠A. Then, use the same theorem to set ∠BDA as 52°. Subtract all the angle measures from 360 (because the sum of the interior angles of a quadrilateral is = 360 degrees). Then divide the result by 2.
360-84-84-52-52=88
=88/2
=44
So z=44°
