So with the given information, I make the length equal x and the width equals x+61. Remember a rectangle has two pairs of equal sides.

So then the equation is 4x+122=406

Do systems and you will find that x equals 71.

The length is 71cm

The width is 71+61=132cm

Answer:

174

Step-by-step explanation:

Given

132, 145, 97, 112, 128, 82

Required

Estimate amount of students in an art class

This is calculated by obtaining the mean of the given data

Mean = \frac{\sum x}{n}

Where n is the number of observations

So;  n = 6

Mean = \frac{132+ 145+ 97+ 112+  128+  82}{6}

Mean = \frac{696}{6}

Mean = 174.0

<em>Hence, the estimated number of students is 174</em>

7w + 6 + 2w = (w + 2)
Sindrei [870]

Hey there!

The correct answer is w = \frac{-1}{2}

7w + 6 + 2w = w + 2          ~ Write the equation

9w + 6 = w + 2                   ~ Simplify

8w + 6 = 2                          ~ Subtract w from both sides

8w = -4                             ~ Subtract 6 from both sides

w = \frac{-1}{2}                                ~ Divide both sides by 8

Hope it helps and have a great day!

Two trains leave stations 560 miles apart at the same time and travel toward each other. One train travels at 90 miles per hour
lana [24]

Answer: the two trains will meet in 2.8 hours

Step-by-step explanation:

Step 1

Speed of train A  = 90mph

Speed of train B = 110 mph

Since both trains  are travelling towards each other , their effective speed will be= 90 mph + 110mph= 200mph

Step 2

we know that Speed = distance / time

therefore Time = Distance / speed

Distance = 560 miles

Speed = 200 mph

Time = 560miles / 200mph

2.8 hours

The graph of the equation y = 1 x + 2 is displayed.
melisa1 [442]

Answer:

A. y = 7x + 2

C. y = 2 - ⁷/3x

D. y - 2 = 4x

Step-by-step explanation:

The equation of any line that would intersect the orange line at the y-intercept, 2, would have the same y-intercept value of 2.

Thus, from the options given, the following equations has y-intercept (b) of 2.

A. y = 7x + 2

C. y = 2 - ⁷/3x

D. y - 2 = 4x

All three equations have a y-intercept value, b, of 2.

Note: option D, y - 2 = 4x, can be rewritten as y = 4x + 2.
