Answer:
x = -2
Step-by-step explanation:
3x+7=-x-1
4x+7=-1
4x=-8
x=-2
Answer: the answer should be 7
Step-by-step explanation: V=πr2h
3=π·1.52·3
3≈7.06858
you can find the radius for the area of the base 7 by dividing by like such 7/3.1459 the squared because remember its in r2 form which give you 1.5 then plug this in for one of two ways to solve A· 1/3 or V=πr2h
Saying "a number" is the same as saying "x"
"Three more than a number" is the same as "three more than x"
If you have three more of something (say, marbles) than someone else, then you have their number of marbles plus three more.
Then, "Three more than x" is the same as "three plus x", or "3 + x"
Hope this helps! :)
Your gross pay and net pay both have to do with taxes and the amount of money you earn, but they differ from one another:
Gross pay: This is the total amount of money you earned during the pay period, your salary multiplied by the number of hours you worked.
Net pay: This number will be less than the gross pay because this is how much you actually take home after taxes are taken out of your check.
