Answer:
x+.8x=27
1.8x=27
x=15
4/5(15)=12
So 15 and 12
Step-by-step explanation:
Answer:
12/10=1.2
Step-by-step explanation:
You just move the decimal one place value to the left. so 12÷10=1.2 which is the same as 12/10=1.2
Answer:
Charles practiced for the relay race for D. 9 hours last week.
Step-by-step explanation:
First, I would find the ratios the ratios for converting hurdle to javelin and javelin to relay.
Hurdle : Javelin ; 5 : 1.5
Javelin : Relay ; 2.5 : 5 or 1 : 2
Next, find the factors compared to the original numbers for hurdle to javelin.
15 / 5 = 3
To find the amount of javelin time they did, multiply 1.5 by the factor we got, 3.
1.5 * 3 = 4.5
Finally, double 4.5, since Charles does twice as much relay than he does javelin.
4.5 * 2 = 9 hours
Answer:
24
Step-by-step explanation:
the area of white board = (2×12) ×4 = 96 sq in.
the area of post-it = 2×2 = 4 sq in
so, numbers of post-it = 96/4 = 24
