Make y the subject:
y = 6 - x
Now, use Elimination.
0 = 3x - 3
Divide both sides by 3:
0 = x - 1
So x = 1.
Substitute back into the equation:
y = 6 - (1)
So y = 5.
Hence, the answers are x = 1, y = 5.
8v + 8b = 240
4v + b = 54....multiply by -2
-------------------
8v + 8b = 240
-8v - 2b = - 108 (result of multiplying by -2)
------------------add
6b = 132
b = 132/6
b = 22 <== buses hold 22 students
4v + b = 54
4v + 22 = 54
4v = 54 - 22
4v = 32
v = 32/4
v = 8 <== vans hold 8 students
Answer: 0.12
5^-2=0.04
the cube root of 27=3
0.04x3=0.12
Answer:
The multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, and 72.
I believe the first one 12+ 6 + 15 = 12 + 15 + 6 is your answer, since you are just moving things around
hope this helps
