How do you do a unit rate?

1 answer:

6 0

To find the unit rate, divide the numerator and denominator of the given rate by the denominator of the given rate. So in this case, divide the numerator and denominator of 70/5 by 5, to get 14/1, or 14 students per class, which is the unit rate.

1st transformation:
$A'=(-3,-4)\\
B'=(-7,-4)\\
C'=(-3,-8)\\
D'=(-7,-8)$

2nd transformation:
When you rotate a point around the origin by 180 degrees, you change both coordinates to opposite values.
$A''=(3,4)\\ B''=(7,4)\\ C''=(3,8)\\ D''=(7,8)$

Y+5=2(x+1)<br><br><br> what is the slope for this Math

Stells [14]

Answer:

Step-by-step explanation:

The slope-intercept form is

y=mx+b, where m is the slope and b is the y-intercept.y=mx+bRewrite in slope-intercept form.Simplify 2(x+1).Apply the distributive property.

y+5=2x+2⋅1

multiply 2 by 1.

y+5=2x+2

Move all terms not containing y to the right side of the equation.Subtract 5 from both sides of the equation.

y=2x+2−5

y=2x−3

the slope is the "m" so the slope is 2

In order to make an A on her project, Sarah needs at least 160 points. She has already turned in part of her work and has been g

antoniya [11.8K]

to get an A, she needs >=160 points and she already has 125 points

let 'x' be the number of points on the last part of her project then

125 + x >= 160

x >= 160 - 125

x >= 35

Sarah needs at least 35 points on the last part of her project.

When Anita planted a large bush in her garden, it was 5 feet tall. Now it is 40% taller. How tall is the bush now?

goblinko [34]

Answer:

7 feet

Step-by-step explanation:

the new height of the bush can be represented in percentage form as 100% + 40% = 140% = 1.40

1.40 x 5 = 7 feet

Method 2

find 40% of 5 feet

0.4 x 5 = 2

Add 5 + 2 = 7 feet
