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
0.08 kilometers per minute.
Just do 4/50 and you’ll get the answer.
3/10+ 5/8
First find a common denominator
multiply top and bottom the same
12/40 +25/40
add
37/40
x + x+1 + x+2 =81
Simplify:
3x + 3 = 81
Subtract 3 from both sides
3x = 78
Divide both sides by 3
x = 26 or C). 26
