x = 10
y = -2
z = -5
-x2 + 6zy = ???
Plug it in:
-(10)(2) + 6(-5)(-2) = ???
-10 x 2 + 6 x 10= ???
-20 + 60 = 40
Therefore, plugging the values in would make it equal 40.
You need to get x by itself. Add 6 to both sides.
x = 14
Answer:
sure
Step-by-step explanation:
Jacqui's tower is taller than miguel's. How did I manage to pull that out? I divide the volume by the product of the length and wide of the base tower and that should give me the height of the tower. <span />
D + q = 110......d = 110 - q
0.10d + 0.25q = 20.30
0.10(110 - q) + 0.25q = 20.30
11 - 0.10q + 0.25q = 20.30
-0.10q + 0.25q = 20.30 - 11
0.15q = 9.30
q = 9.30/0.15
q = 62 <==== there are 62 quarters
d = 110 - q
d = 110 - 62
d = 48 <==== there are 48 dimes
