Hayley has $155 in savings, and her brother Hank has $230. Hayley is saving $10 each week, and her brother is spending $15 each week. After how many weeks will their savings accounts have the same amount of money in them?

What is the best way to set up this word problem to solve?


15x+155=230+10x
15 x plus 155 is equal to 230 plus 10 x

155−15x=10x+230
155 minus 15 x is equal to 10 x plus 230

155+10x=230−15x
155 plus 10 x is equal to 230 minus 15 x

155−10x=230+15x

Answer 1

Answer:

The Correct Answer is The 3rd one, Or C

Step-by-step explanation:

It will take 3 weeks

If its right mark me brainliest if its wrong report me.

Answer 2

Answer:

$155+$10x=$230-$15x

Step-by-step explanation:

weeks= x

$155+$10x=$230-$15x is the correct answer because hayley currently has $155 in her saving and you have to add the 10 dollars she saves each week which is 10x. On the other hand, her brother has $230 and spends $15 dollars every week so that is 15x.

Let angle 1, angle 2, and angle 3 have the following relationships.
Angle 1 and 2 are acute vertical angles
Angle 3 is an obtuse angle adjacent to both angle 1 and angle 2.
What is the sum of the measure of angle 1 and the measure of angle 3?

Answers

180 degrees

Vertical angles are opposite angles that share only a vertex. Since ∠3 is adjacent to both ∠1 and ∠2, this means that ∠3 shares a side and vertex with both of these angles.
This means that ∠3 and ∠1 form a straight line; this makes them a linear pair, which makes their sum 180°.

Yellow Line:

Answers

Answer:

Red Line: y=4

Blue Line: y=-2

Green Line: x=-1

Yellow Line: x=6

Step-by-step explanation:

Red line: the line crosses through 4 on the y axis. Therefore, y=4.

Blue line: the line crosses through -2 on the y axis. Therefore, y=-2.

Green line: the line crosses through -1 on the x axis. Therefore, x=-1.

Yellow line: the line crosses through 6 on the x axis. Therefore, x=6.

This is a bit confusing because when you see a horizontal line your mind might assume it would be an x=. Yet, it is the opposite. Hope this helps!

The list below shows the results of a survey of favorite ice-cream flavors among middle-school students.


18 students voted for chocolate.
12 students voted for strawberry.
20 students voted for vanilla.

What percentage of the students chose vanilla as their favorite ice-cream flavor?

A. 20%
B. 30%
C. 40%
D. 50%

Answers

Answer:

C. 40%

Step-by-step explanation:

There are 18 + 12 + 20 = 50 students in total.

20 students voted for vanilla.

So... 20 out of 50 students voted for vanilla.

20/50 = 2/5

2/5 = 40%

Answer:

C. 40%

Step-by-step explanation:

First you add them together:

12+18+20 = 50

Then, you times both sides of the equation by 2

24+36+40 = 100

You can see that 20 changed to 40, and that's the answer!

Algebra question I don’t get it because you usually have to multiple A by C but there is no C in the problem.

Answers

Ok so basically, when you say multiply A by C, that is simplifying.

And in this case, you are factorising in this question. You turn back into brackets basically.

We have:
72x^2 - 32

x^2 = x squared

factorising means finding the factor of.

(Forget the x squared for the moment to make life easier)

Factors of 72:
1 and 72
2 and 36
3 and 24
4 and 18
6 and 12
8 and 9
(9 and 8 = it repeats so we stop there)

And then factors of 32:
1 and 32
2 and 16
4 and 8
(8 and 4 = repeats so we stop there)

Notice how we see 8 twice in both factors of 72 and 32, this means that we use 8 as the main number we are going to multiply each of the 2 numbers in the brackets by. This is because it is the biggest common factor - this is what we have!

This is what we would have:
8(9-4)

BUT, that is not the answer!
Keep in mind we have the x squared too

But, 32 doesn’t have it?!!

It would be:
8(9x^2 - 4)

Do you get it??

Try to simplify it! Does it equal to 72x^2 - 32?

(And I am so very sorry for the long explanation, once you get the hang of it, it makes sense. Hope my explanation helped) :)

Sean determines that the triangle shown in the diagram has angle measures of 40°, 40°, and 100°. Is Sean correct?

Answers

The bottom left angle is 180 -80=(100)

So the remaining 2 angles are equal 80
As all angles in a triangle are equal to 180

X+5 + x - 5 =80
Simplify
2x=80
X=40

Soo one of the angles are 40-5 which is (35)
And the other is 40+5 which is (45)
So sean is not correct
~sorry sean teehee

Answer:

Step-by-step explanation:

The two angles add to 80 degrees. Two remote angles always equal the exterior angle not connected to them.

That means that

x + 5 + x - 5 = 80

2x = 80

x = 40

The base angle  is

40 + 40 + y = 180

80 + y = 180

y = 100

Note

You could do this much quicker by noticing that

80 + y = 189

y = 100

No he is not right

The given 2 angles are x + 5 which is 45 and x - 5 which is 35

All he got correct was the fact that the third angle is 100 degrees.
