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
Please I need I will Brainliest!!!
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:
$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.

By using double inequality describe all the numbers that are:
a) greater than (−8) but less than (−2)
b) less than 0, but greater than (−5)
c) greater than (−3), but less than 3
Step-by-step explanation:
-8 < x < -2
-5 < x < 0
-3 < x < 3
"greater than" and "less than" is not inclusive of the number written. So
a) -7,-6,-5,-4,-3
b) -4,-3,-2,-1
c) -2,-1,0,1,2
The question should have specified "integers" btw. "All" numbers is impossible to list out since you can have 1.999999999999 but never quite 2

An expression is shown below:
2x3 + 10x2 − 4x2y − 20xy
Part A: Rewrite the expression so the GCF is factored completely.
The given expression can be rewritten as 2x(x²+5x-xy-10y).
The given expression is 2x³+10x²-2x²y-20xy.
What is GCF?GCF stands for the greatest common factor. The greatest common factor of two numbers is the greatest number that is a factor of both of them.
Now, 2x³=2×x×x×x, 10x²=2×5×x×x, 2x²y=2×x×x×y and 20xy=2×x×x×y
Here, the GCF of all the terms is 2x.
So, the expression becomes 2x(x²+5x-xy-10y).
Therefore, the given expression can be rewritten as 2x(x²+5x-xy-10y).

Answer:
12Step-by-step explanation:
So our equation is:
(7x+5)+(5x+3)+(12x-20) = 276
First remove parenthesis:
7x+5+5x+3+12x-20=276
Combine like terms:
24x-12 = 276
Add 12 on both sides:
24x = 288
Divide:
288/24 = 12

You can complete three-tenths of a task in an hour. Your friend can complete one-fifth of the same task in an hour. How long will it take to complete the task if you work together? Explain.
_______ hours.
Answer:
2 hours
Step-by-step explanation:
If you convert 1/5 to tenths it's 2/10.
If you add 2/10 and 3/10 you get 5/10 which would be how much off the task you got done in one hour.
Therefore you times 5/10 by 2 and you get 10/10 so the task is done and it took 2 hours.
