Please help solve for X and AB.

Answers

Answer 1

Answer:

x=3 and AB=20

Step-by-step explanation:

If CB and BD are equal segments then you can solve for x by solving for

3x+6=8x-9

3x+15=8x (Add 9 to both sides)

15=5x (Subtract 3x from both sides)

x=3 (Divide 5 by both sides)

To find AB, substitute 3 and x

7(3)-1

Mackenzie picks some apples.
She eats 3 apples.
Now she has 9 apples.
How many apples did Mackenzie pick to start?
A. 3 apples
B. 6 apples
C. 9 apples
D. 12 apples

Answers

Answer:

d.12

Step-by-step explanation:

its saying she ate 3 an now has 9. so you really add 3 to 9 an your answer is 12. in other words x=9+3 for your level of math. i'll be glad to help her with her home work for now if you would like me to.

Answer: Option D 12 apples

Step-by-step explanation:

SOOOO

She ate 3 apples and after that, she left with the 9 apples

They asked how many did Mackenzie pick.

SO its past tense

we have to add 3 apples that she just ate

so 9+3= 12 apples

I think your teacher is wrong because I think your teacher thought that she had 9 apples actually she has 9 apples after she just ate. So if it was before she has eaten the apples then it would be 6

Tell the teacher that she/he is wrong and give this explanation

I hope this helps you and your teacher

The slope is 1/3 because slope is rise over run so you go up one unit and go right three units.

Answer:

The slope is 1/3

Step-by-step explanation:

Slope is rise over run. Starting from the point (1,-4), the line moves up one unit (rise=1) and then 3 units to the right (run=3) to get to the point (4,-3). Therefore rise over run, or the slope, is 1/3.
