Answer:

Answer:

Bryan needs 9 cups more.

Step-by-step explanation:

Bryan is cooking cupcakes for a bake sale at his club. The recipe calls for 12 cups of flour.

Number of cups of flour, he already has = 3

Lets say he needs x cups more.

So, equation forms = $12=x+3$

=> $12-3=x$

x = 9

Hence, Bryan needs 9 cups more.

Answer 2

Ok, so first of all... You've got to get the same numerator. What's a number that 9 and 8 both share? Hmm... How about 72? So then, 9 would be multiplied by 8 and 8 by 9. And so do the denominators. So, your new fraction would be : 8 32/72 + 5 27/72 which equals 13 59/72 The addition part is actually pretty easy. Just add the whole numbers like a normal addition problem and add the denominators to the denominators and the numerator stays the same. Your final answer should be 13 59/72. Hope this helped!

Find the common denominators within the fractions. So take 4/9 and times the top and bottom by 8 to get 32/72 and 5/8 and times top and bottom by 9 so 45/72. So you will then have 8 32/72 + 5 45/72. Then plus them together. 13 77/72 which equals 14 5/72.

remember, you can do anythingn to an equaiton as long as you do it to both sides (except divide by zero)

solve for h
V=lwh
divide both sides by lw
V/(lw)=h

#1---> let the number you are trying to find be x for the following questions

30%*x=15
x=15/30%
x=50

#2
10%*x=14
x=14/10%
x=140

#3
(4/32)*100
is the same as (1/8)*100= 12.5%

#4
1%* x=11
x=11/1%
x=1100

by the way * means multiply
