Answer:
4
Step-by-step explanation:
<span>(b+3)/7=(b-3)/6
6(b+3) = 7 (b-3)....> cross multiply
6b + 18 = 7b -21 ...>distributive property
6b - 7b = -21 -18 ...>subtract 7b to both sides then simplify
-b = -39 ...> multiply -1 to both sides
b = 39</span>
We have to find two fractions which have a sum of - 7 /36.
5/9 + ( - 3/4 ) =
= 5/9 - 3/4 =
= (5*4)/(9*4) - (3*9)/(4*9)=
= 20/36 - 27/36 = - 7/36
Answer:
C ) - 3/4 and F ) 5/9
Nina used 2 cups. The correct answer is B. Use this formula;
lets assume y is the amount of ounces she used. Lets assume x is the amount of cups she used.
y = x(8)
Replace y with 16.
16 = x(8)
Divide by 8.
2 = x
Thus, 2 cups.
8 1/4 - 3 5/12
Before subtracting have same denomination (divided into equal parts)
1/4 = 3/12
8 3/12 - 3 5/12 = 4 5/6
First subtract the whole:
7 - 3 = 4
Then, the remaining parts:
1 3/12 - 5/12
15/12 - 5/12
10/12
Reduce:
5/6
So: 8 1/4 - 3 5/12 = 4 5/6
