Answer:
Step-by-step explanation:
Well 8 hundredths is also know as 0.08 if we put in in the decimal form.
I hope this helps :D
X: earn per hour during the week
y: earn per hour during the weekend
13x + 14y = 250.90
15x + 8y = 204.70
Multiply the first equation by 4 and the second equation by 7
52x + 56y = 1003.6
105x + 56y = 1432.90
Subtract the first equation from the second:
53x = 429.30
x = 429.30/ 53
x = 8.10
Solve any of the equation for y:
15x + 8y = 204.70
y = [204.70 - 15(8.10)]/8 = 10.40
y - x = 10.40 -8.10 = 2.30
Answer: she earns $2.30 per hour more during the weekend than during the week.
4/3
40/30
60/45
Simply multiply or divide both the 20 and the 15 to get an equivalent ratio.
Looks like a good question, using the mathematical term of "radical."
