Answer:
b
Step-by-step explanation:
The answer is B. -18 is to the left of -8 on the number line.
-18, -17,-16,-15,-14,-13,-12,-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9 and so on. Hopes this helps.
its 64
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
A = 100 B = 130 C = 150
Translated into a system of equations:
A+B+C = 380
B = A+30
C = B + 20
So we find B from the last one:
B = C-20
Plug it in the second one:
C-20 = A+30
A = C-50
Plug it in the first:
C-50 + C-20 + C = 380
3C - 70 = 380
3C = 450
C=150
A = C - 50 = 150 - 50 = 100
B = C - 20 = 150 - 20 = 130
4 times = 4x increased by 7 = 4x+7
1/2
Substitute 1/2 as h you get 16*(1/2) you get 4 and -8*1/2 you get -4 so 4+ -4 = 0
