Well if you make the denominater of the fraction the same, aka finding the lowest common multiple you can find out so what you do is 8 and 6 both go into 24 8 goes into 24 3 times and 6 goes 4 times so you multiply the numerator by how many times the denominator goes into the LCM(lowest common multiple) and get 6/24 and 8/24 meaning justin climbed higher
Answer:
Equation 1: 7x + 2y = 12.8
Equation 2: 6x + 3y = 12
Cost of 1 apple: $1.60
Cost of 1 orange: $0.80
Cost of 1 orange: $Step-by-step explanation:
Let's use the elimination method to solve this
Multiply equation 1 by 3
(7x + 2y = 12.8) x 3 = 21x + 6y = 38.4
Multiply equation 2 by -2
(6x + 3y = 12) x -2 = -12x - 6y = -24
The x terms will cancel each other out
21x + 6y = 38.4
-12x - 6y = -24
9x = 14.4
Divide by sides by 9 to isolate the x variable
9x/9 = 14.4/9
x = 1.6
This means an apple costs $1.60
Plug the new x into one of the original equations to find y; we'll use equation 1
7(1.6) + 2y = 12.8
11.2 + 2y = 12.8
Subtract 11.2 from both sides
11.2 + 2y = 12.8
- 11.2 - 11.2
2y = 1.6
Divide both sides by 2
2y/2 = 1.6/2
y = 0.8
This means an orange costs $0.80
Answer:
J
Step-by-step explanation:
- The answer is natural then whole integers and ratiinal
Y=5x because the the hourly wage is going up by 30 and the length employment is going up by 6 so you divide both of them with hourly wage on top which will give you 5
