Answer:
31
Step-by-step explanation:
Multiply the numbers 7 * 4, which gets your 28.
= 28+6-12/4
Divide the numbers 12/4, which gets you 3
=28+6-3
Add/Subtract the numbers 28+6-3
= 31
D=12
Because if you write down the equation 4x-8=40 and plug in 12. 4 times 12 is 48
. 48-8 equals 40
Answer:
Worked 40 hrs in week
Pay $300 for week
Step-by-step explanation:
Hours: 7-11a.m = 4
12-4p.m = 4 So, 4+4=8 hrs per day
So, 8 hrs per day × 5 days a week (8×5)=40
Worked 40 hrs in week
Pay: $7.50/hr So, $7.50×40 hrs (7.50×40)=300
So, $300 pay for week
