PLEASE HELP
d=2r show all steps pls

Answers

Answer:

Step-by-step explanation:

1.1     Solve   d-2r  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  d-2r  = 0 and calculate its properties

Which job has the highest hourly pay?
Frank's Furters
Two of them are tied.
Babysitting
Harriet's Hair Styles

Answers

Answer:

Harriet's Hair Styles

Step-by-step explanation:

Frank's Furters $6.24 /hr

Harriet's Hair Styles $80 for 12 hours weekly

$80 / 12 hr = $6.66/hr

Babysitting $250 a month for 10 hours after school a week. (Assume 4 weeks is a month.)

$250 / (4 wk * 10 hr/wk) = $250/ 40 hr = $6.25/hr

Answer: Harriet's Hair Styles

Harriet's Hair Styles has the highest hourly pay at $6.67 per hour.

To determine which job has the highest hourly pay, we need to calculate the hourly wage for each job based on the information provided.

Frank's Furters: $6.24 per hour.

Harriet's Hair Styles: $80 for 12 hours weekly.

Babysitting: $250 a month for 10 hours after school a week.

Let's calculate the hourly wage for each job:

Frank's Furters: $6.24 per hour.

Harriet's Hair Styles: $80 for 12 hours weekly

= $80 / 12 hours

= $6.67 per hour.

Babysitting: $250 a month for 10 hours after school a week

= $250 / (4 weeks x 10 hours)

= $6.25 per hour.

Hence, Harriet's Hair Styles has the highest hourly pay at $6.67 per hour.

what tis -2(x-6) + 7= 35
. Im am very need of help.
ten points

Answers

You weren't clear with your question, but I am assuming you want to solve for the variable "x."

-2(x - 6) + 7 = 35

-2x + 12 + 7 = 35; distribute the -2

-2x + 19 = 35

-2x = 16; isolate the x variable (the variable you want to solve)

x = -8; divide by -2 to isolate the x variable

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

1) Distribute

[tex]-2(x-6)+7=35\\-2x+12+7=35[/tex]

2) Add the numbers

[tex]-2x+12+7=35\\-2x+19=35[/tex]

3) Subtract 19 from both sides of the equation

[tex]-2x+19=35\\-2x+19-19=35-19[/tex]

4) Simplify

A. Subtract the numbers

[tex]-2x+19-19=35-19\\-2x=35-19[/tex]

B. Subtract the numbers

[tex]-2x=35-19\\-2x=16[/tex]

5) Divide both sides of the equation by the same term

[tex]-2x=16 \\\frac{-2x}{-2} =\frac{16}{-2}[/tex]

6) Simplify

A. Cancel terms that are in both the numerator and denominator

[tex]\frac{-2x}{-2} =\frac{16}{-2}[/tex]

B. Divide the numbers

[tex]x=-8[/tex]
