Charlie likes to eat 3/4 cup of cereal each morning for breakfast. How many servings will he be able to eat from a box that has

Naddika [18.5K]

He will be able to eat 16 serving from the box that has 12 cups of cereal in it

Step-by-step explanation:

Charlie likes to eat 3/4 cup of cereal each morning for breakfast

We need to find how many servings he will be able to eat from a box

that has 12 cups of cereal in it

To solve the problem

Divide the number of cubs in the box by the quantity he like to eat
If the divisor in the division problem is a fraction we change the division to multiplication and reciprocal the divisor

∵ There are 12 cups in the box

∵ Charlie likes to eat $\frac{3}{4}$ cup

- Divide the number of the cups in the box by $\frac{3}{4}$

∴ The number of serving = 12 ÷ $\frac{3}{4}$

Change the division sign to multiplication sign and reciprocal $\frac{3}{4}$

∵ The reciprocal of $\frac{3}{4}$ = $\frac{4}{3}$

∴ The number of serving = 12 × $\frac{4}{3}$

∴ The number of serving = $\frac{48}{3}$

∴ The number of serving = 16

He will be able to eat 16 serving from the box that has 12 cups of cereal in it

How can I find x? Click for picture.

romanna [79]

Answer: You add up all the terms given of EACH angle, and make this an addition problem that is "equal to 180" ; since all triangles have three angles that add up to 180 degrees. Then you solve for "x".
__________________________________________________
(as follows) ; to get: " x = 29 ⅔ ° " .
_______________________________________

3x + 4 + 2x + x + 8 = 180 ;
_______________________________________
Combine the "like terms" ;

3x + 2x + x = 6x ;

4 + 8 = 12

So, we have: 6x + 12 = 180 ;

Now, subtract "12" from each side of the equation:
__________________________________________
6x + 12 − 12 = 180 − 12 ;
__________________________________________
to get:

6x = 178 ;

Now, divide EACH SIDE of the equation by "6" ; to isolate "x" on one side of the equation; and to solve for "x" ;
______________________________________
6x / 6 = 178 / 6 ;

to get: x = 178/6 = 29 ⅔ ° .
______________________________________
x = 29 ⅔ ° .
