Answer:

Below

Step-by-step explanation:

First we will evaluate the brackets (BEDMAS)

      - (5.8 - 9.6) / (-0.2)^2 + 3

      - ( -3.8 ) / ( 0.04) + 3

Because there is a negative sign on both the outside and inside of a bracket, that number becomes positive

      ( 3.8 ) / ( 0.04 ) + 3

Calculate this :

      = 95 + 3

      = 98

Hope this helps! Best of luck <3

NNADVOKAT [17]

Answer:

c = $5,400

Step-by-step explanation:

Given:

c = 0.9s

where,

s = amount sold

c = commission on sales

How much commission will he or she earn if the amount sold is $6,000?

Find c when she = $6,000

c = 0.9s

= 0.9 × 6,000

= 5,400

c = $5,400

(c, s) (5400, 6000)

Find x so that (x,-14) is a solution to 2x+3y=12
Monica [59]

Answer:

27

Question:

Find x so that (x,-14) is a solution to 2x+3y=12 .

Step-by-step explanation:

So we are asked to replace y with -14 and solve for x in the equation:

2x+3y=12.

2x+3y=12 with y=-14:

2x+3(-14)=12

2x-42=12

Add 42 on both sides:

2x=54

Divide both sides by 2:

x=27.

So the x-coordinate that corresponding to y=-14 is 27.

Verify that:

(27,-14) is a point satisfying 2x+3y=12.

Replace x with 27 and y with -14:

2(27)+3(-14)=12

54+-42=12

12=12 is true so our work must be right.

A company can buy packages of 500 sheets of paper for $4. At that rate, how much paper can be bought for $2000? Group of answer
Alexandra [31]
Your answer is 250,000. There are two ways to do this problem.

1) Solve 500/4 to find out how many sheets of paper you get per every dollar. — Your answer is 125 sheets for $1. Then you multiply that answer by 2000, and get 250,000. Which means you get 250,000 sheets of paper for $2000.

2) You can divide 2000 by 4 & that gets you 500, you can then multiply that by 500 & you will get 250,000.

Hope this helps.
