Add 3u to both sides.
Subtract 7 from both sides.
7u = 63
u = 9
7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 or 7 x 14 = 98 Dont you have a calculator...?
okay well the answer to that is 91 got it (PS. you should know it!) :) peace!
58.
Add 3u to both sides. Subtract 7 from both sides. 7u = 63 u = 9
First locate -3. Then to add 7 you move 7 places to the right (and you will arrive at 4): _____________________________________________________ _____________________ move right 7__________________ ______________ →→→→→→→→→→→→ __________ _____________ ↑ _________________________ ↓ __________ ___---+---+---+---+---+---|---+---+---+---+---+--- ___ ____ -5 _____ -3 __________0______________4___ 5 _____ _____________________________________________________
The answer is 380, I hope. :P
7 + 7 + 7 + 7 + 7 + 7 + 7 or 7 X 7 = 49.
7+7+7+7+7+7+7+7 is the same as 7 multiplied by 8, so the answer is 56.
Yes.
