She spent 1/3 of 3/4. Or about 0.25, or about 1/4 in fractions.
You would use order or operations to solve this problem
4 to the second power is 16 -------> 12+16= 28
Your answer would be 28
11. 2x+3x+1=21
5x+1 =21
5x=20
x=4
TU= 2(4) which is 8
UB= 3(4)+1 which is 13
12. 4x-1 +2x-1=5x
6x-2=5x
-2=-1x
2=x
X=2
TU= 7
UB= 3
TB=10
Problem 13:
2x-8=x+17
2x=x+25
x=25
AB =42
BC=42
AC=84
Problem 14:
3x-31
-x+6
=
2x-37 for BC part now we solve for x
x+6=2x-37
6=x-37
43=x
So :
X=43
AB=49
AC=98
BC=49
The answer is 140 percent
If you just mean the product of the prime factors of 39 then this is the answer
39 = 3 x 13
