Question

What is the answer for 8 and 9 please show steps

Answer 1

look at explanation

Explanation:

3.5 = 3y

divide each side by 3 so only y is left.

y=1.6666666

-5 =
`(w)/(6)`

multiply each side by 6 so only x is left

w = -30

Hope this helps!

Answer 2

Solution 8 :

3.5 = 3y

= 3y = 3.5

= y = 3.5 ÷ 3 ( transposing ×3 from LHS to RHS changes ×3 to ÷3 )

= y = 1.17

Therefore ,

y = (d) 1.17

Solution 9 :

= -5 = w/6

= w/6 = -5

= w = -5 × 6 ( transposing ÷6 from LHS to RHS changes ÷6 to ×6 )

= w = -30

Therefore ,

w = (b) -30
