So, the answer to this problem is x = 9/2 or x = 4.5.
5+2(x-1)= 12 So you need to get rid of parentheses, which is that you have to distribute. 5+2x-2= 12 -5 -5 (Inverse) 2x-2= 7 +2 +2 (Another inverse) 2x= 9 2 2 (Divide)
well......For example... 56/7=8 That's how you do it....
you divide a whole number by figuring out how many times the divisor can got into the dividend
Can the fraction 2/1 be simplified
Answers
Yes. 2/1=2
It's the same as saying 2 divided by 1.
Yes, If you want a whole number, 2 but if you want a fraction then no it can't be simplified. Hope it helps! :-)

Which is a good comparison of the estimated sum and the actual sum of 7 9/12 + 2 11/12?
Answers
7 9/12 = 7.75 2 11/12 = 2.917
So we can round both of these up.
7.75 rounds to 8 2.917 rounds to 3
8 + 3 = 11
So the estimated sum is 11.
7 9/12 + 2 11/12 = 10 2/3
So the actual sum is 10 2/3.
The estimated sum is a pretty good estimate to the original number.
7 9/12 + 2 11/12 ((12*7)+9)/12+((12*2)+11)/12
93/12+35/12
128/12 divide by 2
(128/2)/(12/2)
64/6 divide by 2
(64/2)/(6/2)
32/3
10 2/3
a bag contained 3/4 pound of marbles. each marble weighed 1/36. After Ashley removed some marbles from the bag, it weighed 1/3 pound. How many marbles did Ashley remove?
Answers
she removed 12 marbles because 3×12=36 and you can do commutative property and do 12×3= what? 36!
