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 _____ _____________________________________________________
7+7+7+7+7+7+7+7 is the same as 7 multiplied by 8, so the answer is 56.
Yes.
7 Times 7 Equals7 plus 7 plus7 plus7 plus7 plus7 plus 7, or 7 times 7, equals 49.
The sum of 7 plus 7 plus 7 plus 7 plus 7 plus 7 plus 7 is 49. This can be calculated by adding each number together: 7 + 7 = 14, 14 + 7 = 21, 21 + 7 = 28, 28 + 7 = 35, 35 + 7 = 42, and finally 42 + 7 = 49.
