Answer:
28*4/7
Step-by-step explanation:
4/7
the 7 represents the 28. 28 is a multiple of 7.
<u>28</u> * <u>4</u> = <u>112</u> = 16
1 7 7
<u><em>there are 16 girls</em></u>
also we know 4*7=28 so if we count the multiples of 4, there is 4 8 12 and the 4th multiple is 16.

Answer:
Step-by-step explanation:
You can create a ratio from the provided recipe,
for every 6 cups of brown sugar you need 9 cups of white sugar so it would be 6:9
?:24
24/9=2.6
6x2.6=15.6
so for 24 cups of white sugar you would need about 16 cups of brown sugar.
Answer:
(2*3)=6; 60= (2*3)*2*5 (prime factorization)
The numbers in the parenthesis can't be taken out because they are the HCF
So just move the 2 and the 5 on both sides and you'll get two pairs that are (6,30) and (12,30)
Answer:
b = 24
Step-by-step explanation:
<u>Concepts</u>
The Pythagorean Theorem states that the sum of the squares of the two other sides on a right triangle is equal to hypotenuse (longest side) squared. It can be represented by the equation 
. We can also use this formula to solve for the other two legs in the right triangle.
<u>Application</u>
In this case, we're asked to find the length of b in the right triangle, given c as 26 and a as 10. Now, we just apply the formula and solve for b.
<u>Solution</u>
Step 1: Set up equation and simplify.
Step 2: Subtract 100 from both sides.
Step 3: Take square root of both sides.
Therefore, b = 24.
When solving the equation, you first have h- 9/5. So it would by x=(h - 9/5). But you are not done yet. you still have to divide it by R to get x. So the final equation is x=(h - 9/5) ÷ R
