<h2>Hey there!</h2>

<h2>Given,</h2>

length = 2x-5 and breadth(width) = x+9

<h3>We know that:</h3><h3>Perimeter of a Rectangle is = 2*(l + b)</h3>

= 2*(2x-5 + x +9)

= 2*(x+4)

= 2x + 8

<h3>So, the perimeter of the given rectangle is = 2x + 4</h3><h3 /><h2>Hope it help you</h2>

Two planes just took off from St. Louis, MO. The first plane is traveling 3.5 times as fast as the second plane. After Traveling

Yanka [14]

Answer:

Speed of first plane is 350 miles per hour

Speed of second plane is 100 miles per hour

Step-by-step explanation:

Let the speed of the second plane be X

Then the speed of the first plane will be 3.5 X

Distance travelled by first plane is 9.5 *X

Distance travelled by second plane is 9.5 * 3.5 X

Difference of distance between the two plane is

$9.5 * 3.5 X - 9.5 *X = 2375\\23.75 X = 2375\\X = 100$ miles per hour

Speed of first plane is 3.5 *100 = 350 miles per hour

Speed of second plane is 100 miles per hour

Write each equation in slope - intercept form, then find the slope and y-intercept:

Rasek [7]

1/2x + 3/4y = 4 ....multiply everything by 4
2x + 3y = 16
3y = -2x + 16
y = -2/3x + 16/3

In y = mx + b form, the slope will be in the m position and the y int will be in the b position

y = mx + b
y = -2/3x + 16/3

so ur slope is -2/3 and ur y int is (0,16/3)

How do you know when ratios are equivalent and when they are not equivalent

White raven [17]

Ratios are equivalent when that can be reduced or multiplied to be the same number.
Ex) 1:4 is the same as 2:8 or 4:16
10:20 is the same as 8:16 or 1:2

They are not equivalent if you can’t do this

Write the percent as a decimal.

Alinara [238K]

Answer:

12% = 0.12

Percent means 'per 100'. So, 12% means 12 per 100 or simply 12/100. If you divide 12 by 100, you'll get 0.12
