Answer:
The number of hamburgers sold was 126.
Step-by-step explanation:
Let h = number of hamburgers sold
let c = cheeseburgers sold
c+h = 378
c = 2h
Substitute c =2h into c+h =278
c+h =378
2h+h = 378
Combine like terms
3h = 378
Divide by 3
3h/3 =378/3
h =126
The number of hamburgers sold was 126.
Answer:
8 ft 8 in
Step-by-step explanation:
104/12 = 8.666...
This shows that there are 8 total feet because there are 12 inches in a foot
Then, multiply 8*12 to get 96 in order to get the remainder of the inches left that do not make up one whole foot.
Then subtract 96 from 104 (104-96) to get the remainder which is 8 inches.
He used 11/12 of sugar.
(1) I multiplied the factors and denominators by eachothers denominators
(2) I ended up with the two converted fractions: 8/12 and 3/12. The reason for this step is because if the two fractions have the smae denominator, it helps make it easier to add the fraction.
(3) I added the fractions, getting the sum of 11/12

5(x + 2) = 6x + 3x - 14
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition] Combine like terms: 5(x + 2) = 9x - 14
- [Distributive Property] Distribute 5: 5x + 10 = 9x - 14
- [Subtraction Property of Equality] Subtract 9x on both sides: -4x + 10 = -14
- [Subtraction Property of Equality] Subtract 10 on both sides: -4x = -24
- [Division Property of Equality] Divide -4 on both sides: x = 6
