Answer:

Step-by-step explanation:

Perimeter of a rectangle=(length+width)×2

Let W=x, L=2x+2

25=[(2x+2)+x]×2

25=[2x+2+x]×2

Solve for x

25/2=3x+2

25/2-2=3x

25-4/2=3x

21\2=3x=7/2=x

A train traveled at a constant rate of f feet per second. how many feet did it travel in x minutes? (a) 60f x (b) fx 60 (c) x 60
sdas [7]

Distance travelled by train in x minutes is equal to 60fx feet as per given constant rate of f feet per second.

As given in the question,

Train travelled at a constant rate f feet per second

Let d be the distance travelled by train in x minutes

1 second =f feet

60 seconds = (60f) feet

1 minute = (60f) feet

x minutes = (60fx)feet

Therefore ,distance travelled by train in x minutes is equal to 60fx feet

as per given constant rate of f feet per second.

Estimate the line of best fit using two points on the line 100 90 80 70 (e, 80) 60 30 20 10 (2.20) 10 O A. y= 2x O B. y = 2x+10
nexus9112 [7]

Answer:

y = 10x

Step-by-step explanation:

Given

The attached plot

Required

The line of the best fit using (8,80) and (2,20)

We have:

(x_1,y_1) = (8,80)

(x_2,y_2) = (2,20)

Calculate slope (m)

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{20 - 80}{2- 8}

m = \frac{-60}{-6}

m = 10

The equation is then calculated using:

y = m(x - x_1) + y_1

y = 10(x - 8) + 80

Expand

y = 10x - 80 + 80

y = 10x

Find the Difference.<br> 27,202 -3,489-
Valentin [98]

Answer:

23,713

Step-by-step explanation:

27,202 - 3489 = 23,713.

I'm not sure if you meant to put a minus sign at the end, or you just meant to put an equal sign?

Line up the numbers with the largest number on top. Then subtract from the number above it by the number below it. Whenever you need to, you can borrow from the next place value. Ask any questions you need to.
