If the sum of two numbers is x

Then the equation is like this:

a+b = x

Then it says one of the number is 12. Change either a or b into 12

12 + b =x

If we want to find the other number, we need the make it into the subject

b = x - 12

Hope that help.

Y would be the other unknown number.

12 + Y = X

12-12+Y=X-12

Y=X-12

She needs 3/4 cup of water she needs 10 more servings what's the answer A 1/1/5 b 3/1/4 c 7/2/4 d 8/2/3

Eddi Din [679]

<h2><u>Corect option</u> :</h2>

$= \color{plum}\tt(C) 7 \frac{2}{4}$

<h2><u>Answer with steps</u> :</h2>

Quantity of water she needs $= \tt \frac{3}{4} \: cup$

Number of servings she needs = 10

Number of cups of water she will need :

$= \tt \frac{3}{4} \: \times 10$

$= \tt\frac{30}{4}$

$=\tt 7\frac{2}{4} \: cups$

Thus, she needs $\tt 7\frac{2}{4} \: cups$ of water.

Therefore, the correct option is $\color{plum}\tt(C) 7 \frac{2}{4}$
