Answer:
C
Step-by-step explanation:
b is the y value of the equation.
8a = -3b - 5 Let b = - 7
8a = -3*-7 - 5 Combine
8a = 21 - 5 Combine the right again.
8a = 16 Divide by 8
8a/8 = 16/8
a = 2
Answer:
12 hours
Step-by-step explanation:
In 1 hour jack mows 1/4 of the lawn
Together they mow half a lawn in 1.5 hours
Which is a whole lawn in 3 hours
in one hour together they mow 1/3 of the lawn
It takes Jill x hours to mow the lawn
in one hour Jill mows 1/x of the lawn
Working together in one hour
jack + jill = together
1/4 + 1/x = 1/3
1/x = 1/3 - 1/4
1/x = 4/12 - 3/12
1/x = 1/12
Cross multiply
12 = x
It takes Jill 12 hours to mow the lawn
