Answer:
The system of equations is
and
Fred's age is 36 years old and Nathan's age is 9 years old
Step-by-step explanation:
Let
f -----> Fred's age
n ----> Nathan's age
we know that
-----> equation A
----> equation B
equate the equations and solve for n
Find the value of f
therefore
Fred's age is 36 years old and Nathan's age is 9 years old
6y = 24 -3x
divide both sides by 6.
y = (x)/2 +4
Answer:
x+13
Step-by-step explanation:
x +13
x: the number
Answer:
49 + 9x units
Step-by-step explanation:
perimeter is sum of all the sides
Answer:
x = 68
Step-by-step explanation:
Square both sides of the equation. This gives us:
x - 4 = 64
Then add 4 on both sides. This gives us:
x = 68
