Answer 5

can i help

Answer 6

Answer 7

When you look at it try to multiply the answer bye the one you are trying to multiply with then divide you mite get the answer or not that is what i do but i dont always get the answer right

Answer 8

1.
Simplify brackets
2.5x−10.5=64×0.5x

2 Simplify 64×0.5x to 32x
2.5x−10.5=32x

3 Subtract 2.5x from both sides
−10.5=32x−2.5x

4 Simplify 32x−2.5x to 29.5x
−10.5=29.5x

5 Divide both sides by 29.5
−0.35593220339=x

6 Switch sides
x=−0.35593220339
this is what i got for the first one!!
