Answer:
Step-by-step explanation:
Find the GCF of the numbers 48, 6 and 26.
The largest number each can be divided by is 2, which is the GCF.
Find the GCF of
The GCF is always the smallest exponent, so is the GCF
Combine the two GCF for the answer
Answer:
<h3>
present age of son = 10 </h3><h3>
present age of father = 40</h3>
Step-by-step explanation:
Let, present age of son be 'x'
present age of father be 'y'
y = 4x→ equation ( i )
After five years,
Son's age = x + 5
father's age = y + 5
According to Question,
Put the value of y from equation ( i )
Distribute 3 through the parentheses
Move variable to L.H.S and change it's sign
Similarly, Move constant to R.H.S. and change its sign
Collect like terms
Calculate the difference
Now, put the value of X in equation ( i ) in order to find the present age of father
plug the value of X
Calculate the product
Therefore,
Present age of son = 10
present age of father = 40
Hope this helps..

Try the first table value and see what you get from the various choices. For x = 1, the answer choices give you
... A: y = 5×1 = 5
... B: y = 1 + 1 = 2
... C: y = 1 + 2 = 3
... D: y = 2×1 = 2
Both B and D give the correct value (2), so we need to try another table entry. For x = 3 (the second table entry), the answer choices give you
... B: y = 3 + 1 = 4
... D: y = 2×3 = 6
Only selection D gives you the correct value (6). The appropriate choice is
... D. y = 2x
