Answer:
-2
Step-by-step explanation:
a - 6 - 6a = 4
a-6a=10
-5a=10
a=10/-5
a=-2
Answer:
No for the first one, yes for the second.
Step-by-step explanation:
Plug in the given numbers and see if it works.
15(1) + 3(4) = 10
15 + 12 = 10.
27 ≠ 10
Since 27 does not equal 10, we can already see that solution (1,4) will not work for these equations.
Now for the second problem, do the same thing.
10 = 1 + 9.
This is true, but remember to check the second equation just to be sure.
10 = 4(1) + 6
10 = 4 + 6
This is also true, so it (1,10) is a solution for the second system of equations.
Hello!
I believe the answer is 2.

Answer: 252 ft^2
Explanation: The area of a square is 36, there are five squares which equals 180. Then you have to add the area of the four triangles, which one triangle has the area of 18. Which equals 72 for all the triangles. If you add 180 and 72 it equals 252
Answer:

Step-by-step explanation:
Hello,
let s assume that m+n is different from 0
we have this equation and we need to find m as a function of t, s, and n

<=>

for t-s different from 0, so t different from s
hope this helps
