Let's say the number is x
75%of x is 15
75%x=15
0.75x=15
x=15/0.75
x=20
or you can say 3/4x=15
x=15*4/3
x=20
Answer:
-22k - 67m
Step-by-step explanation:
You have to use the Distributive property:
8(k + m) - 15 (2k + 5m)
8k + 8m - 30k - 75m
Now simplify:
8k - 30k + 8m - 75m
-22k - 67m
Be careful with positives and negatives!

and 
Step-by-step explanation:
Given the expressions:
1)
2)
To find:
The expressions equivalent to the given expressions.
or the expressions which are not equivalent to any of the given expressions.
Solution:
First of all, let us solve the brackets from the given expressions.
can be written as (because when we multiply a negative sign with negative, it becomes positive.)
Similarly can be written as (because when we multiply a positive sign with negative, it becomes negative.)
Therefore, the answer is:
is equivalent to and
is equivalent to and .
The expressions which are equivalent to neither:
and
The length of CA is opposite of angle B and since the hypotenuse is known, you can write an equation like this: sin 40 = x/7 which simplifies to sin40 * 7 = x. The answer is A
