Hi there!
In order to solve, you can use substitution. This means that you use one equation and solve for one variable, then use that one equation and plug it into the other equation. Here's how we'd do it:
WORK:
x = 12 - y (since x is already solved for, we'll use that to plug into the other given equation.
2(12 - y) + 3y = 29 (using substitution)
24 - 2y + 3y = 29
24 + y = 29
y = 5
Plug the value of y back into the first equation
x = 12 - 5
x = 7
ANSWER:
A - x = 7, y = 5
It seems as though you're having some trouble with these questions, PLEASE MESSAGE ME!! I'd be more than happy to help you work through as many problems as you need until you get the hang of it (plus, it doesn't cost you any points!)
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
9: D 10: A
Step-by-step explanation:
Answer:
D. ∛4a^2 / a
Step-by-step explanation:
∛4a / ∛a^2
= ∛(4a)* ∛a / ∛a^2 * ∛a
= ∛4a^2 / ∛a^3
= ∛4a^2 / a
Answer is D. ∛4a^2 / a
Answer:
24
Step-by-step explanation:
The LCM of 6 and 8 is 24 because 24 is the smallest number that is both a multiple of 6 and a multiple of 8
The ratio is equivalent because 1/20 is 5 which means 9/10 is equal
