3 3/5= 18/5
18/5 divided by 3/5= 6
Answer:
1. 5r-8=r
2.3x-4=120
3. x-20=27
4. 3x+10=46
5. 2x+12=16
6. 8+4x=56
7. 16/x=2
8. x+6=24
9. 5x+19=67
10. 6-4x=38
Step-by-step explanation:
First, use the distributive property and split 2 off from 1/2 in the hours category.
(2) (1/2)
Next, multiply 2 1/4 times 2, the first integer in the distributive equation.
2 1/4*2 = 4 1/2
For now, put 4 1/2 aside.
Then, multiply 2 1/4 by 1/2.
2 1/4*1/2 = 1 1/8
Now, add the two products together
4 1/2 + 1 1/8 = 5 5/8
Answer is 5 and 5/8
Hope this helps!
