diamong [38]3 years ago
6 0

Answer: d= -5

Step-by-step explanation:

1.5d+3=-4.5

Subtract 3 from both sides to isolate 1.5d

1.5d+3-3=-4.5-3

1.5d=-7.5

Now divide by 1.5 to completely isolate d

\frac{1.5d}{1.5}=\frac{-7.5}{1.5}

d=-5

Goryan [66]

Answer:

D. $680

Step By Step Explanation:

100 pages are typed. Each page coast $5 to type.

100 x 5 = 500

40 pages are revised once. It costs $3 to revise a page once.

40 x 3 = 120

10 pages are revised twice. It costs $3 to revise a page once so it will cost $6 to revise it twice
