The answer is 120 seconds.
Why?
180 divided by 4.5 is 40 seconds
200 divided by 2.5 is 80 seconds
Then add the seconds.
But I don’t understand how you walk so many meters in 180 seconds
3 3/5. - 4 1/2
find a common denominator
3/ 5 = 6/ 10.
1/2. = 5/10
3 6/10. - 4 5/10
- 1 1/10
Answer:
40
Step-by-step explanation:
Divide 12 by .40 (the percentage) to figure out what the full number would be.
The sum means addition
v + 3
Answer:
77 children and 186 adults
Step-by-step explanation:
After a LONG time testing out numbers, I finally found two numbers. What I did was used the equation 3x + 5.5y = 1254. I kept filling in two numbers that can add to 263. For example, I filled in the variables with 77 and 186. Like this: 3(77) + 5.5(186) = 1254. 77 times 3 equals 231 and 186 times 5.5 equals 1023. Add those two numbers together to get 1254. So, there were 77 children and 186 adults.
