You need to divide this one :)
Hope this helps
Answer:
Yes, Yes, No, Yes.
Step-by-step explanation:
2/5 as a decimal = 0.4
4 ÷ 0.4 = 10
1 is correct.
2 x 10 = 20
2 is correct.
6 x 10 = 60
3 is incorrect.
10 ÷ 2 = 5
4 is correct.
3(x + 4) = 1/2x - 8
...multiply 3
3x + 12 = 1/2x - 8
...subtract 1/2x
2.5x + 12 = -8
...subtract 12
2.5x = -20
...divide by 2.5
x = -8
