When multiplying with fractions you can multiply the top and the bottom independantly
5*3 = 15
1*4 = 4
so 5 * (3/4) = 15/4
For this, we can set up a proportion.
Their aim was 15000, so if they raised 100% of their goal, they wouldve raised exactly 15000.
They raised 557%, so how much did they make?
Proportion:
$15000 100%
$x 557%
Our expression would be x=$15000*557% divided by 100%, which would be $83550, so... a lot of money.
(we did an “x” formation with the proportion, ie “connected” x with 100, and “connected” 15k and 557. The number connecting to x is what we divide the equation by, and the other two are multiplied and then divided by the first number connecting to x. Otherwise we couldve calculated 557% of 15000 and gotten the same result. Whichever way is easier for you :) )
Answer:
4h-7
Step-by-step explanation:
Step by Step Solution
STEP1:Equation at the end of step 1 (1 - 2h) + 2 • (3h - 4) STEP2:
Final result :
4h - 7
We have 4(x^2 - 2x + 4) - 7 = 4x^2 - 8x + 16 - 7 = 4x^2 - 8x + 9;
So, 4x^2 - 8x + 9 = <span>ax^2+bx+c
