Step-by-step explanation:
Answer = 91
So first use the order of operations: parentheses, exponents, multiply/divide, add/subtract to do 3^4 (this is an exponent) first which is 81. Then do the multiplication, 2•5, which equals 10. Finally add the 81+10 to get 91 as your final answer. Hope that helps :)
Add 8 to both sides which would give you x/3=-4 and then multiply by 3 which would give you x= -12
Answer:
8) 4(n)+12
9) 21 + 4(m) + (2(m)+7)
10) 3 (S+21)
Step-by-step explanation:
I did this quickly, hopefully they are correct. May not be the same format as you wish (especially for 9)
Answer:
Multiplication
Step-by-step explanation:
If you were to solve 8x x x, you wouldn't know what that means. So, normal people place variables and numbers together to represent multiplication.
