I think the answer is number 3
Answer:
117
Step-by-step explanation:
every time x goes up by one you add 5 to y
Answer:
looks to me like it could be (A.)
Step-by-step explanation:
i might be wrong if i am im sorry
First set up your two equations:
x + y = 90
x = 2y - 30
Then substitute what x equals in the second equation into the first equation:
(2y -30) + y = 90
Now solve for y:
3y -30 = 90
3y = 120
y = 40
Then use y = 40 and substitute the value for y into one of your original equations and solve for x. I'll choose the first one, but either one will work.
x+ 40 = 90
x = 50
So your solution is x = 50 and y = 40
Y= 40+(20x), where you asking for something like that?
