R =
I think “represent” is asking you to solve to a number.
10r + 4 = 8
Subtract 4 from both sides of the equation:
10r = 4
Divide both sides by 10:
r = 0.4
Check the math:
10(0.4) + 4 =
4 + 4 = 8
To find the solution to the given expression, we simply isolate the unknown variable m and perform the necessary operations. The solution is as follows.
(3/5)*(2m-10) = (2/3)*m + 10
15*[(3/5)*(2m-10) = (2/3)*m + 10]
9(2m-10) = 10m + 150
18m-90 =10m + 150
18m - 10m = 150 + 90
8m = 240
m = 240/8
m = 30
First, we multiply the whole expression to the least common denominator (LCD) which is 15. Multiplication and division were then performed accordingly. The terms containing the variable m were transposed to the left side of the equation. Mathematical operations were then applied to get the final value of m which is equal to 30.
fifty five hundredths is equal to 0.55
You multiply .65 times 100 and you get 65 which is 65% of 100
