Answer:
10 weeks
Step-by-step explanation:
Let's set an equation for you and your brother.
You have $90 plus $18 for every week you save (x).
90+18x
And your brother has $120 plus $15 dollars per week that he saves (x)
120+15x
You want to have the sum of the money equal so combine the two concluded statements
90+18x=120+15x
Arrange them so that you have like terms on each side
90+18x-15x=12+15x-15x
90+3x=120
90-90+3x=120-90
3x=30
x=10
"x" is our number of weeks you and your brother save so the answer is 10 weeks
Just to be sure you can use our equation and plug 10 for every time you see x to make sure our answer is right.
An additive inverse is the value you can add to a given value such that the sum is "0"..
Your answer is choice A
18xy + (-18xy) = 0 Since these are like terms.. the key here is understanding that like terms must have the same exact variables raised to the exact same powers. We can add like terms. We cannot add unlike terms.
Answer:
figure B is ×3 larger than figure A
Step-by-step explanation:
if you divide the lengths of the sides of figure B by the sides of figure A, you will get 3.
Answer:
31.62
Step-by-step explanation:
If we know it's a right triangle, we can use the Pythagorean Theorem to solve this problem.
10^2 + 30^2 = 1000
Find the square root of 1000 and get your answer of 31.62.
Hope this Helps!
Good Luck!

Answer:
x2
Step-by-step explanation:
If the graph has a gap at the x value c, then the two-sided limit at that point will not exist.
If the graph has a vertical asymptote and one side of the asymptote goes toward infinity and the other goes toward negative infinity, then the limit does not exist.
