244 divided by 60 = 4.0666
To find this answer, we should subtract 2 1/2 from 3 1/4. The simplest way to do this is to turn them into improper fractions, found the least common denominator, and subtract the numerators.
3 1/4=13/4
2 1/2=5/2
The least common multiple is 4, so we should multiply the numerator and denominator of 5/2 by 2.
5/2=10/4
Now we can just subtract the numerators.
13/4-10/4=3/4
Using the math above, we can see that it saves D. 3/4 hours.
If I'm interpreting this right, it's -36 since a half times ten is 5... so it comes down to 5-41 which equals -36.
Step-by-step explanation:
Represent Wilbur with W and Orville with O
The equation connecting both flights is
W - 120 = O
W = 364 feet
364 - 120 = 246
O = 246
Answer:
9.5 inches
Step-by-step explanation:
The relationship is presumed to be ...
(first week's growth) + (second week's growth) = (growth in two weeks)
(first week's growth) + 3.43 inches = 12.93 inches . . . . . fill in the numbers
Subtract 3.43 from both sides of the equation:
first week's growth = 12.93 inches - 3.43 inches
first week's growth = 9.50 inches
The plant grew 9.50 inches in the first week.
