Answer:
6
Step-by-step explanation:
9 and 2/5 is the equivilent to 9 and 4/10
9 4/10 - 3 4/10 = 6 0/10
3x + 7 = -x - 1
3x + 7 + = -1
4x + 7 = -1
4x = -1 - 7
4x = -8
x = -2
1 - 2x + 5 = 4x - 3
-2x + 6 = 4x - 3
6 = 4x - 3 + 2x
6 = 6x - 3
6 + 3 = 6x
9 = 6x
x = 6/9
x = 2/3
i helped you with the first two questions so you can see how you can solve it.
hope this helps, God bless!
Z-12=6
you take the 12 and add it to both sides making it look like:
z-12+12=6+12
which also looks like
z-0=6+12
z-0 = z
so now you have
z=6+12
6+12 = 18
SO Z=18!!!
your answer is 18
Answer:
140
Step-by-step explanation:
you would find the perimeter 8+8+6+6=28, then you multiply it by the height so it would be 28x5=140
