Answer:
From my knowledge I would say M= 31 km
Step-by-step explanation:
For each hour you subtract 20 kilometers.
Since the sixth hour was 51 kilometers,to find how many kilometers for the seventh hour we simply subtract 20 from 51.
51- 20 = 31
I really hope this helps:)
The number is fifteen. I know this because when you think about it, all they are asking is what subtracted from five makes ten. So that makes fifteen.
The formula to find AB is a^2+b^2=c^2, where a is the left side, b is the bottom, and c is x. 2^2 is 4, so it asks for the sq. rt. of 8, which is 2.83 (rounded to the nearest hundredth).
Answer:
x>2 and x<1
Step-by-step explanation:
first one:
6x+9-9>21-9
6x>12
6x÷6>12÷6
x>2
second one:
9x-5+5<4+5
9x<9
9x÷9<9÷9
x<1
The expression has a value of 15 when you divide by 2.
