angle A and angle B are supplementary angles. If m angle A = (2x + 26)° and m
angle B = (x + 25)°, then find the measure of angle B.


x=43

Answers

Answer:

m angle B = 68°

Step-by-step explanation:

Since they are supplementary, they add up to 180°

(2x+26) + (x+25) = 180

add like terms together

3x+26+25=180

simplify the left side

3x+51=180

subtract 51 from both sides

3x=129

divide both sides by 3

x=43

Then you plug in x into measure B

(43)+25

-(7-9)z-6z=8(-6+2) solve for z

Answers

Answer:

(-(7-9))(z)-6z= 8(-6+2)

Simplify

-(-2)(z) -6z =8(-6+2)

Multiply 8*-6 and 8*2

2z -6z= -48+16

Combine like terms

2z+-6z =-32

-4z=-32

Divide both sides by -4

z=8

ANYONE HELP PLEASE<3

Answers

Answer:

y = (2/3)x + 7

Step-by-step explanation:

Slope intercept form is y = mx +b

1) We start off with y =

2) m = slope. Since we know that the slope is 2/3 we can plug it in. y = 2/3x

3) b is y-intercept which = 7.

Put it all together: y = 2/3 x + 7

The answer is

y = 2/3x +7

Hope this helped!

Have a supercalifragilisticexpialidocious day!

how do you solve this problem step by step
y=x+3
y=x-1

Answers

Step-by-step explanation:

since they have the Same slop (1) and different y-intercepts then they're parallel and there isn't a solution for this.

set them like an equation: x+3=x-1
then cancel the equal terms on both sides of the equation which would end you up with: 3= -1, after that your answer would be no solution since there’s no terms in order to get you an answer.

60% of 15 is what answer

Answers

The correct answer is 9. :)

Answer:9

Step-by-step explanation:

Think of it this way:

If 15=100%

then x= 60%

So what you do is you multply 60 times 15 and divide it by 100 to give you the answer of 9. To me this is the simplest way to do it, I believe it’s called butterfly multiplying. You cross multiply and then you divide.
