5A + 7 = 3A + 7 + 2A
We need to solve for A.
3A + 7 + 2A = 3A + 2A + 7 = 5A + 7 (We can add 3A and 2A because it's the same variable, so we add the coefficients)
5A + 7 = 3A + 7 + 2A
5A + 7 = 5A + 7
5A + 7 is always equal to 5A + 7 because it's the same equation. So the equation got infinitely many solutions.
The first answer is B because the bottom half of the proportions are how many km/minutes he CAN run, while the top half of the proportion is how many he WILL run.
He will run 60km in 285 minutes.
Using proportions, it is found that each of the 6 people got $0.5.
<h3>Proportions:</h3>
- This question is solved by <em>proportions</em>, using a rule of three.
- $3.00 is shared between 6 people, which are Larry, Curly, Moe, Alvin, Simon and Theodore. How much did each people(1 person) get?
The <em>rule of three</em> is:
$3.00 - 6 people
$x - 1 person
Applying cross multiplication:



Each of the 6 people got $0.5.
