Step-by-step explanation:

1)Subtract 7m from both sides.      2)Step 1: Subtract 2x from both sides.−5x+3−2x=2x−1−2x                              -5x+3-2x=2x-1-2x

−7x+3=−1                                           -7x+3-3=-1-3

Step 2: Subtract 3 from both sides.  -7x=-4

                                                            Step 3:Divide both sides by -7

−7x+3−3=−1−3                                       -7x/7=-4/7

The area of the square and rectangle are equal. If the side of the square is 40 cm, and the breadth (width) of the rectangle is 25 cm, find the length and perimeter of the rectangle.

Answers

Area of square is length times width. Which are the same due to the laws of it being a square. So 40x40 = 1600cm^2. The area of a rectangle is width times height. We know the area is 1600cm so we know that 1600/25= height (64cm). If there are two equal parallel lines on a rectangle then 25 + 25 + 64 + 64 = perimeter (178cm).

error analysis: a contractor purchases 7 dozen pairs of padded work gloves for $99.12. she incorrectly calculates the unit price as $14.16 per pair for the expense report. what is the correct unit price? what is the error?

Answers

Answer:

Unit Price= $1.18

The error is that the contractor divided $99.12 by 7 and didn't multiply the 7 by the dozen (12) first, which lead to a mistake.

Step-by-step explanation:

To find the unit price:

1) multiply 7x12 = 84

  to get the total amount of gloves

2) divide 99.12 by 84

  to get the unit price

What is the equation of a line, in general form, with a slope of -2 and a y-intercept of 8?

2 x + y - 8 = 0
x + 2 y - 8 = 0
2 x - y + 8 = 0

Answers

Answer:

The first one plz brainliest

Step-by-step explanation:

2x + y - 8 =0

- 2x from both sides

Y - 8 = -2x

Then add 8 to both sides

Y = -2x + 8

The second one = -1/2x + 4 when its in slope intercept form

And the third one = y = 2x + 2

So it’s the first equation that ve slope of -2 and y intercept of 8

Answer:

2x + y - 8 =0

Estimate the quotient by rounding each number to the nearest whole number.
33.7 ÷ 9.5
Enter your answer below and show how you got the answer.

Answers

Answer:

3

Step-by-step explanation:

33.7 rounded = 30

9.5 rounded = 10

30/10 = 3

NOT POSITIVE

It’s 4 because 33.7/9.5=3.5 and when that is rounded it’s 4. Or I have this suggestion 34/10=3.4 round this value it’s 3. So it’s either 3 or 4

Edward paid $4.77 in sales tax on an item that cost $53.00 before tax. At that rate, how much would he pay in sales tax for an item that costs $61.00 before tax?

Answers

Answer:

He would pay $5.49

Step-by-step explanation:

edward would pay $5.49 on sales tax for an item that costs $61.00.

net price: $61.00

sales tax rate: 9.00%

the formula for finding sales tax is sales tax amount = net price x (sales tax percentage / 100).

total price = net price + sales tax amount.

so,  

$61.00 x (9 / 100) = $5.49

total = $61.00 + $5.49 = $66.49

because this question is not asking for the total price, we can dismiss that.

input $5.49 as your answer. you've then completed this question.

if you have any confusion, please reach out to me and i'll try to help you as best as i can :).
