Answer:
N=1
Step-by-step explanation:
1/2n+7=n+14/2
Multiply 2 on both sides to get rid of fraction
N+14=n+14
In this situation the answer is automatically 1
Check:
1/2(1)+7=1+14/2?
7 1/2= 7 1/2 ✔️
Answer:
x = 10
PQ = 27
QR = 20
Step-by-step explanation:
You can add up PQ and QR and set it equal to PR. Solve for x.
(2x + 7) + (2x) = 47
2x + 7 + 2x = 47
4x + 7 = 47
(4x + 7) - 7 = 47 - 7
4x = 40
4x/4 = 40/4
x = 10
Now, use the solved x-value to find PQ and QR.
PQ = 2x + 7
PQ = 2(10) + 7
PQ = 20 + 7
PQ = 27
QR = 2x
QR = 2(10)
QR = 20
