First one: 3/4 = __/8
to get 8, they did 4*2
so whatever you do to the bottom, you do to the top
3*2=6
the first answer is - 3/4 = 6/8
the second one: 3/8 + 3/4
we need to find the LCD (Lowest Common Denominator)
3/8 = 8,16,
3/4= 4,8
the LCD is 8, now we just need to add the numerators
3/8 + 3/8 = 9/8
we could covert it into a mixed fraction
9/8 = 1 1/8
i hope this helped!!
Answer:
The main systems of equations is missing, but I was able to add one so you can therefore use the same understanding and steps to approach any systems of linear equation.
Step-by-step explanation:
The step by step explanation is as shown in the attachment
Convert 20 min to hrs: 20/60 = 1/3 hr
Let t = time on the bikethent-(1/3) = time on the bus
Write a dist equation Dist = speed * time:Bike dist + bus dist = 26 mi6t + 30[t-(1/3)] = 26:6t + 30t - 10 = 2636t = 26 + 1036t = 36t = 1 hr on the bike
6 mph for 1 h = 6 mi from house to the bus station
Check solution by finding the distance6(1) + 30(2/3) =6 + 20 = 26 mi
Answer:
B. e - 75 < 26
Step-by-step explanation:
After addressing 75 envelopes, a political volunteer has fewer than 26 envelopes left to address. Which inequality can be used to find the total number of envelopes (e)?
A. 75 - e < 26
B. e - 75 < 26
C. 75 - e > 26
D. e - 75 > 26
Total number of envelopes = e
The political volunteer has addressed 75 envelopes
The political volunteer has fewer than 26 envelopes left to address.
This means he has less than 26 envelopes to address after addressing 75 envelopes out of a total of e envelopes
The inequality that can be used is
e - 75 < 26
The correct answer is
B. e - 75 < 26
Answer:
$2.43
Step-by-step explanation:
2.19×0.11=0.2409
2.19+0.24=2.43
