(-3) + 7 = 4
You can use a number line by simply starting at 7 then moving back 3 spaces because it's negative. Then you will get positive 4.
Answer:
You will have $20,495.30
Step-by-step explanation:
If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365; and so forth, regardless of the number of years involved.
if you want me to solve (-3x)²
the answer is 9x²
Recall your d = rt, or distance = rate * time
notice, the time he took to cover 63 miles with the wind, is the same amount of time he took against it with 51 miles only, let's say, he took "t" hours long
and he was cycling at a rate of "r"
thus

solve for "r"
I believe it is B. Sorry I’m not the best at math but hope this helps !!
