Answer:
it's going to be 4n so its going to be 4...
Step-by-step explanation:
Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5
Answer:
650
Step-by-step explanation:
Answer:6%
Step-by-step explanation:
Decrease = 1500 - 1410= 90
% decrease = (90/1500)*100%
= 6%
25.65 ÷ 15 = 1.71
So, the answer to this problem is 1.17
