5g - 7g + 4 + 2g
= 5g - 7g + 2g + 4
= -2g + 2g + 4
= 4
[5g -7g +2g gives us 0]
Answer:
The answer should be M = 5/9(R - 21)
Step-by-step explanation:
To find this value, follow the order of operations to isolate M.
R = 9/5M + 21
R - 21 = 9/5M
5/9(R - 21) = M
Answer:
$37.86
Step-by-step explanation:
Multiply 29.99 by 0.0625 to get the sales tax
29.99x0.0625=1.87
Multiply 29.99 by 0.20 to get the tip
29.99x0.20=5.998
Round 5.998 to 6
Add 1.87 to 29.99
29.99+1.87=31.86
Add 6 to 31.86
31.86+6=37.86

Megan will have to pay $2, 260 for surgery.
Step-by-step explanation:
1. Translate percent into decimal:

14, 600 - 13, 140 = 1, 460
4. Add (to find out how much Megan pays):
1, 460 + 800 = 2, 260
