If 90 is 80% of the whole value, then 1/4 of 90 added to 90 will be the value, because 1/4 of 80% (which is 20%) added to 80% will give us 100%
So,
90/4=12.5
90 + 12.5=102.5
At least, that's my take on it
To find the width of the rectangle, you want to use the formula a=lw. First, substitute the values for the variables x=width. So 161cm squared equals 14 cmx. Then divide 14 to both of the sides. Divide 161 by 14=14 divided by 14. So the width of this rectangle is 11.5cm..
Answer:
-15
Step-by-step explanation:
start from the inside and go out.
So first plug in -3 into g(x)
g(-3) = -3 - 7 = -10
then plug in -10 into f(x)
f(-10) = 2(-10) + 5 = -15
so f(g(x)) = -15
