Answer:
The number is 14
Step-by-step explanation:
Let n be the number. We can set up an equation:
2(n+20)=5n-2
Distribute the left side
2n+40=5n-2
Move like terms to one side. Note that the sign flips when we move a term from one side to the other.
40+2=5n-2n
42=3n
Divide both sides by 3
n=14
Answer:
LCM(21,25) = ( 21 × 25) / 1
LCM(21,25) = 525 / 1
LCM(21,25) = 525

Given:
Point Q is on line segment PR.
QR = 3x, PQ = x + 6, and PR = 5x – 4.
To find:
The numerical length of PQ.
Solution:
Since, point Q is on line segment PR, so by segment addition property, we get
The value of x is 10.
Now,
Putting x=10, we get
Therefore, the numerical length of PQ is 16 units.
