Answer:
Billy used 28 mins 30 sec to mow the lawn and Bobby used 43 mins 30 sec to now the lawn both within 72 mins
Step-by-step explanation:
let x represent Billy
let x+15 represent Bobby
x + x + 15 = 72
2x = 72 - 15
2x = 57
2x/2 = 57/2
x = 28.5 minutes = 28 minutes 30 seconds
Bobby = x + 15
= 28.5 + 15
= 43.5 minutes= 43 minutes 30 seconds
Answer:
Step-by-step explanation:
So we have the equation:
First, subtract 3 from both sides:
Definition of absolute value:
Divide both sides by 6 for both equations:
And we're done!
Equation a^2 + b^2 = c^2
c = longest side, unknown
The answer is D.
