Hey there! :D

So, those both will be equal to 180 degrees. Consecutive angles are supplementary. 

2x-20+3x= 180

5x-20=180

Add 20 to both sides.

5x=200

x= 40

I hope this helps!

2x-20+3x=180
Add like terms
5x-20=180
Add 20 on both sides
5x=200
Divide by 5 on both sides
X=40

What is the slope of the line through (-9, 6) and -3, 9) and explain?
olya-2409 [2.1K]

Answer:

m = 1 / 2

Step-by-step explanation:

The slope formula is as follows:

m = y2 - y1 / x2 - x1

Now we insert the numbers into the formula:

m = 9 - 6 / -3 - (-9)

m = 3 / 6

m = 1 / 2

Order the values of the differences from least to greatest. First, write the fractions as decimals. StartFraction 4 Over 5 EndFr
ddd [48]

Complete Question:

Ms. Perez's biology class grew sunflowers to learn about plants. During the first week, the average sunflower grew 3 inches. The table shows the difference from the average for three students.

Order the values of the differences from least to greatest.

Student: Raj. Difference (in.): 4/5

Student: Clara. Difference (in.): -1 1/2

Student: Jacob. Difference (in.): 0.9

Answer:

-1.5, 0.8 and 0.9

The greatest is: 0.9

By student names: Clara, Raj and Jacob

Step-by-step explanation:

See comment for complete question

Given

Differences:

\frac{4}{5}, -1\frac{1}{2}, 0.9

Required

Order from least to greatest

We have: \frac{4}{5}, -1\frac{1}{2}, 0.9

First convert fractions to decimal

\frac{4}{5} = 0.8

-1\frac{1}{2}= -1.5

-\frac{3}{4} = -0.75

So, the differences become:

0.8, -1.5, 0.9

Now arrange from least to greatest

-1.5, 0.8 and 0.9

From the above representation,

The greatest is: 0.9

By student names, we have:

Clara, Raj and Jacob

This is done by simply replacing the numbers with the student name.
