On time jimmy needs $42 to buy a pack of comic books. he has saved $18 and plans to work as a babysitter to earn $6 per hour. which inequality shows the minimum number of hours, n, that jimmy should work as a babysitter to earn enough to buy a pack of comic books? 6n ≥ 42 + 18, so n ≥ 10 6n ≤ 42 + 18, so n ≤ 10 18 + 6n ≤ 42, so n ≤ 4 18 + 6n ≥ 42, so n ≥ 4

so

Step-by-step explanation:

Let

n------> the number of hours working as babysitter

we know that

The inequality that represent the situation is equal to

Solve for n

Subtract both sides

Divide by both sides

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
