HELP ASAP!!!! Please

Mathematics
1 answer:
alexandr1967 [171]3 years ago
7 0

Step-by-step explanation:

as the sum of the interior angles of a triangle is 180..so

a+b+c=180

(x+2)+x+(6x+10)=180

now

add all variables and all numbers

so

8x+12=180

8x=180-12

8x=168

x=168/8

x=21

now put the values

a=x+2

21+2=23

b=x

21

c=6x+10

136

verify

23+21+136=180

Write the equation y- 6 = _5(x + 1) in<br> slope-intercept form.
Georgia [21]

Answer:

y = -5x + 1

Step-by-step explanation:

y - 6 = -5 (x + 1)

distribute -5 (x + 1) by multiplying

y - 6 = -5x - 5

than add 6 to both sides

y = -5x + 1

In scientific notation, how can you tell if it is less than or greater than 1? Explain
svlad2 [7]

Answer: See below

Step-by-step explanation:

In scientific notation, you can tell that it is greater or less than 1 by looking at the exponent. The scientific notation looks like _.__×10⁻. Note: The little lines are blanks for you to fill in. The dot at the bottom is a decimal.

If the exponent on top of 10 is positive, you are moving the decimal to the right side, making the number greater.

If the exponent on top of 10 is negative, you are moving the decimal to the left side, making it smaller and smaller.

By those statements, you can tell if a number is greater or less than 1 by looking at the exponent.
