17) 10•6 = 4w

Multiply:

60 = 4w

Divide:

60/4 = 4w/4

15 = w ———————————



18) 180° - S = 65°

Isolate the variable (subtract 180° on both sides):

-S = -115

You can’t have a negative angle so you divide -1 on both sides:

S = 115 ———————————

Answer:

17. w = 15   18. S = 115°

Step-by-step explanation:

17. 10 · 6 = 4w

<em>combine like terms:</em>

=> 60 = 4w

<em>divided by 4 on both sides:</em>

=> w = 15

18. 180° - S = 65°

<em>subtract 180° on both sides:</em>

=> -S = -115° => S = 115°

Solve the inequality.
xenn [34]

Answer:

x < -24(option

Step-by-step explanation:

-¼x - 12 > -6

Add 12 to both sides

-¼x - 12+12 > -6+12

-¼x > 6

Divide both sides by -¼

x < 6 ÷ -¼

Please note that the inequality sign changes when divided by negative (minus). This is a rule in inequalities.

x < 6 × -4

x < -24
