Answer:
7/2 or 3 1/2
Step-by-step explanation:
7/8*4/1=28/8
Simplify= 7/2 or as a mixed fraction = 3 1/2
Hope this helps
Can I have the brainliest if I am right?
Step By Step:
With each expression we will first simplify (combine like terms), then substitute, and then solve.
First Expression:
1/2x + 4
Simplify:
There is no like terms so we result in 1/2x + 4 still
Substitute:
1/2x + 4
1/2(2) + 4
Solve:
1/2(2) + 4
1 + 4 = 5
Second Expression:
x + -1/2x - 2
Simplify:
x + -1/2x - 2
1/2x + (-2)
Substitute:
1/2x + (-2)
1/2(2) + (-2)
Solve:
1/2(2) + (-2)
1 + (-2)
1 - 2 = -1
Answer:
None of the answers are correct from what I can see. Although, we do know that the two expressions are not equivalent considering we got two completely different answers, so your answer could not be A or B. Next, we know that one expression equals 5, which can remove D and leave us with only C. This leaves us with only to guess of what the answer is.
Answer:
Subject 's' in terms of 't'
![s = \frac{t-4}{5}](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7Bt-4%7D%7B5%7D)
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<u><em>Given that the subject 't in terms are 's'</em></u>
Given that t = 5 s +4
subtracting '4' on both sides, we get
t - 4 = 5s +4-4
t - 4 = 5 s
Dividing '5' on both sides ,we get
![\frac{t-4}{5} = \frac{5s}{5}](https://tex.z-dn.net/?f=%5Cfrac%7Bt-4%7D%7B5%7D%20%3D%20%5Cfrac%7B5s%7D%7B5%7D)
![\frac{5s}{5 } = \frac{t-4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B5s%7D%7B5%20%7D%20%3D%20%5Cfrac%7Bt-4%7D%7B5%7D)
![s = \frac{t-4}{5}](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7Bt-4%7D%7B5%7D)
