Answer:
105/8 = 13 1/8 = 13.125
Step-by-step explanation:
The first step is to turn the (-5 5/8) into a mixed number. The mixed number you should be getting is - 45/8. The second step is to convert the (-2 1/3) into a mixed number as well, your second mixed number should be -7/3. Next multiply the two fractions, - 45/8 x (-7/3) = 315/24.
We can simplify 315/24 by dividing by 3, so you'll divide 315 divided by 3 and 24 divided by 3 and you should get ... 105/8. So 105/ 8 is equal to
13 1/8. If you need this fraction in decimal form it is 13.125.

We want to determine x from the expression
b(5px - 3c) = a(qx - 4)
Expand each side.
5bpx - 3bc = aqx - 4a
Subtract aqx from each side.
5bpx - aqx - 3bc = - 4a
x(5bp - aq) - 3bc = - 4a
Add 3bc to each side.
x(5bp - aq) = 3bc - 4a
Divide each side by 5bp - aq
x = (3bc - 4a)/(5bp - aq)

Answer:
I don't really know if its right I'm super sorry if it isn't
Step-by-step explanation:
23)
8m + 3(2+8m) = 6-6m
8m + 6 + 24m = 6-6m
32m + 6 = 6-6m
- 6 from both sides
32m = -6m
38m = 0
∴ m = 0
25)
-7 +x = 8x - 7(-7x +1)
-7 + x = 8x + 49x - 7
-7 + x = 57x - 7
+ 7 on both sides
x = 57x
∴ x = 0
27)
2(3n + 9) - 12 = -4(5 + 5n)
6n + 18 - 12 = -20 - 20n
6n + 6 = -20 - 20n
+ 20n on both sides
26n + 6 = -20
- 6 on both sides
26n = -26
∴ n = -1
