Answer:
250
Step-by-step explanation:
One quarter of 100 would be 25, so adding a zero to 100 (1000) would also mean adding a 0 to 25. Therefore, 250
Solve for x
so assuming that the fractions are
(9/4)-(1/*2x))=4/x then
get all x on one side
add 1/(2x) to both sides
9/4=(4/x)+(1/(2x))
make common denomators with x and 2x
common denomenator is 2x
4/x times 2/2=8/(2x)
9/4=8/(2x)+1/(2x)
add
9/4=9/(2x)
make common denomators with 4 and 2x
common denomator is 4x
9/4 times x/x=9x/(4x)
9/(2x) times 2/2=18/(4x)
9x/(4x)=18/(4x)
multiply both sides by 4x to clear fraction
9x=18
divide both sides by 9
x=2
You have to add .7+.7+5+5=11.4
Answer:
4
Step-by-step explanation:
f(g(2)) means "put 2 into g(x) and then take that answer and put it into f(x)"
Given:
and
Now, let's find g(2) first:
g(x) = x - 1
g(2) = 2 - 1
g(2) = 1
Now, lets put this into f(x). So we have:
That is f(g(2)) = 4
