Answer:
Step-by-step explanation:
250=1/2(20)(17+s)
250=10(17+s)
250=170+10s
10s=80
s=8
<span>X/2 + 3/4 = 7/4
We want to isolate X by itself. Subtract 3/4 from both sides
X/2 = 4/4
X/2 = 1
Multiply both sides by 2 to cancel out the 1/2 on the same side of the X
X = 2</span>
2520 is the lowest.
Use this: 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1.
This is divisible by all single digit numbers, and 1 is irrelevant.
Hope this helps!
Answer:
B
Step-by-step explanation: Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
