When it says the temperature drops 59°, this is to be seen as a negative number. We set the math problem up this way

5° (now) - (drops) 59° = -54°

Wouldn't it be -54. Because when you subtract 5-59 you get a negative number... IT WOULD BE FREEZING THERE!!! I HOPE THIS HELPED

For which value of x is the equation 3(x+2)+x=2x+16 true?
Arturiano [62]

Answer:

1) take the first part of the equation and work it by multiplying (x+2) by 3

3(x+2)+x

3x +6+x

2)put the answer you got into the question you were given

3x + 6+x =2x +16

3)group the x variables and the non x variables

3x +x -2x =16 -6

4) Now work the equation you have

3x+x-2x=16-6

4x-2x=16-6

2x=16-6

2x=10

5) you divide both sides by the x variable

2x=10

2x/2 =10/2

x=5

therefore x is 5

Ms jenkins has a grass lawn that is 24m wide and 30m long. mr jenkins cuts the grass at a reate of 9m per minute. how long will
Kisachek [45]

It will take Mr. Jenkins 1 hr and 20 minutes to cut all the grass.

To know how long it will take Mr. Jenkins to cut all the grass, get the total area of the lawn and divide it by the rate Mr. Jenkins cut the grass.

The area of the lawn can be calculated using the formula for the area of a rectangle given by:

A = l x w

where l is the length and w is the width.

Using this formula, the grass lawn that is 24 m wide and 30 m long has an area of:

A = l x w

where

l = 30 m

w = 24 m

A = 30 m x 24 m

A = 720 m^2

Meanwhile, the time it will take Mr. Jenkins to cut the grass lawn with an area of 720 m^2 can be computed using the rate.

amount = rate x time

720 m^2 = 9 m^2/minute x t

t = 720 / 9

t = 80 minutes = 1 hr 20 minutes

Subtract x

2x−3−x=0

Subtract x

from 2x

x−3=0

Add 3

x=3
