Answer:
1. 20x+40
2. 6f+6g
3. 77-28x
Step-by-step explanation:
<u>Use distributive property for all</u>
1) 10(2x+9)-50
20x+90-50
20x+40
2) 6(f+g)
6f+6g
3) 77-28x
4) 3.2(5w+3)
16w + 9.6
$48.30
If the dinner was $42.00 and they wanted to give a 15% tip, then to find that start by multiplying 42 by 0.15
42.00 x 0.15 = 6.3

42 + 6.3 = 48.3

..........
Work Shown:
sand/gravel = 5/3
x/750 = 5/3
3x = 750*5
3x = 3750
x = 3750/3
x = 1250
