The answer is C. You pay $128 in the third hour for both. Hope this helped
I believe x=116 and z=26. 4z-40=64
4z=104
z=26
180-64=116
Supplementary means the 2 angles add up to 180 so...
124+(2x+4)=180
124+2x+4=180
124+2x+4-4=180-4
124+2x=176
124-124+2x=176-124
2x=52
2x/2=52/2
x=26
plug in and check
124+2x+4=180
124+2 (26)+4=180
124+52+4=180
176+4=180
180=180
I think X is 2. But I am not sure, cuz I don’t know what you teacher is really asking you to do.
2/7 is the probability that the first satellite sends a weak signal. That leaves 6, one of which sends a weak signal. So the probability that the second also sends a weak signal is 1/6. Combine these and we get 2/7×1/6=1/21.
