Answer:
B will be the answer...
Step-by-step explanation:
The second equation in system B is only in terms of y, so we need to use elimination to eliminate the x term from the second equation in system A.
To do that, we need to multiply the first equation by 5.
5 (-x − 2y = 7)
-5x − 10y = 35
Add to the second equation. Notice the x terms cancel out.
(-5x − 10y) + (5x − 6y) = 35 + (-3)
-16y = 32
Combining this new equation with the first equation from system A will get us system B.
-x − 2y = 7
-16y = 32
Cuboid has 6 faces. If each face was 2m squared, that would be 2m squared times 6 which is 12m squared
Answer:
x=145
Step-by-step explanation:
simply subtract 35 from both sides, so you can isolate the variable. once done, you will get that x=145
Basically that’s it but write it down by yourself
30*30=900
hope this helps!
