Answer:

x =  - 4.5 \\

Step-by-step explanation:

15(2 - x) = 13(3 - x) \\ 30 - 15x = 39 - 13x \\  - 15x + 13x =  - 30 + 39 \\  - 2x = 9 \\  \frac{ - 2x}{ - 2}  =  \frac{9}{ - 2}  \\ x =  - 4.5

hope this helps

Answer:

-4.5

Step-by-step explanation:

15(2-x)=13(3-x)

Expand parentheses:

30-15x=39-13x

Add 15x to both sides:

30=2x+39

Subtract 39 from both sides:

2x=-9

Divide both sides by 2:

x=-4.5

Hope this helps!

24.5 is 33 1/3% of what number?
julia-pushkina [17]

Answer: 73.5

Step-by-step explanation:

The percent <em>33 1/3% </em>represents 1/3 of 100%. We can multiply 33 1/3% by 3 and get 100%. We need to find what 24.5 is 33 1/3% of.

Since 1/3 x 3 = 100%, then 24.5 x 3 must equal the number we're trying to find.

24.5 x 3 = 73.5.

Therefore, 24.5 is 33 1/3% of 73.5. I hope this helps, and good luck!
