1 is 117 because 18x6.5 is 117
It isn't easy really but you can always divide the number out. For example 50% of 200 is 100 by dividing 200 by 2 or 25% of 100 is 25 by dividing 100 by 4 since 25% is equivalent to 1/4
-12 + 3x + 2 = 5x - 10 - 8x
-10 + 3x = -3x -10
-10 + 6x = -10
6x = 0
x = 0
Answer:
(-5,-1)
Step-by-step explanation:
2x+y=9 -> y=-2x+9
3x-y=16
3x-(-2x+9)=16
3x+2x-9=16
5x-9=16
5x-9 (+9)=16 (+9)
5x=25
x=5
no plug in 5 to x in any equation above
2(5)+y=9
10+y (-10)=9 (-10)
y=-1
so the answer is (-5,-1)
hope it's correct! and hope i helped
Answer:
below
Step-by-step explanation:
consecutive angles are supplementary in parallelogram
q+t = 180
3x+5+9x-17 = 180
12x-12 = 180
x-1 = 15
x=16
r=t = 127°
q=s = 53°
