Answer:
3·4·5 is greater than -3·-4·-5
Step-by-step explanation:
3·4·5 = 60
-3·-4·-5 = -60
If said number is x, that means that twice (2 times) a number and 2x-7=13. Adding 7 to both sides, we get 2x=20 and by dividing both sides by 2 we get x=10. For 2, we see that the sum of a number and 6 is first priority, so we have (x+6)*7=-43. Dividing both sides by 7, we get x+6=-43/7. After that, we subtract both sides by 6 to get -43/7-6=x
The answer is A in my opinion
Answer:
4.92 hours
Step-by-step explanation:
Let x = the number of hours left to work. I am converting the fraction to a decimal to make it easier to work with.
x + 3 + 5 + 2.08 = 15
Move constants to the right
x = 15 - 3 - 5 - 2.08
Do the math
x= 4.92
If 8 men ----------------------------- >take 2 days to lay 100 feet
then
they can lay 50 feet in a day.
Each man lays 50/8 or 6.25 feet per day.
<span>3 men can lay 3 * 6.25 = 18.75 feet per day. </span>
<span>150/18.75 = 17.14 days.
the answer is </span>17.14 days.
