Answer:
Step-by-step explanation:
24 + 36 = 12*2 + 12*3
= 12* (2 + 3)
= 12 * 5
= 60
4.110 = four and eleven hundredths.
(33/4) / (2/8)
when dividing with fractions, flip what u r dividing by, then multiply
33/4 * 8/2 = 66/2 = 33...hmm...not an answer choice
let me try something..
(3 3/4) / (2/8) =
15/4 * 8/2 =
30/2 =
15 <====possibly this one if ur problem is : (3 3/4) / (2/8)
Answer:
Step-by-step explanation:
This is an inverse proportion.
men = k / Time So first we need to find k
k = men * Time Substitute values
k = 15*80
k = 1200 Notice the units are man days.
Now what happens if we increase the number of men to 20? What happens to the number of days.
20 = 1200 / time Multiply both sides by time
20*time = 1200 Now divide by 20
time = 1200/20
Answer: time = 60 days
Answer:
Step-by-step explanation:
For example, if f(x) = 2x + 7
then f(-3) = 2(-3) + 7
f(-3) = 1
