Answer:
there is no pictures. so there for i can not answer your question
60-3d + 20-6 =4d
74-3d =4d
-3d =4d -74
-7d = -74
D=74/7
A: 7! and
<span>B: 5040
you only have 7 slots with 7 * 6 * 5 * 4 * 3 * 2 * 1</span>
<span>I got 0.10,Hopefully that helps!</span>
So you make your equation 4x+20+40=180.
Add like terms and get 4x+60=180.
Subtract 60 from both sides, get 4x=120.
Divide boths sides by 4, get your answer of x=30.
Hope this helps
