Answer:
x=5/2
Step-by-step explanation:
4x-2=2x+3
1) Add 2 to both sides:
4x=2x+5
2) Subtract 2x from both sides:
2x=5
3) Divide both sides by 2:
x=5/2
Lets consider SAM's age is 'x' and Hank's age is 'y'
So as per given data Sam's age is 5/3 times of Hank's age
so x = 5/3 * y
3x = 5y --> equation 1
and also sum of their ages is 24
so, x + y = 24
we need to find Hank's age (y)
so x = 24 - y
Now replace x value in equation 1
3(24-y) = 5y
72-3y = 5y
72 = 3y+5y
8y= 72
y= 72/8
y = 9 years.
So the Hank's age is 9 years

Answer:
16x- 20y=20
Step-by-step explanation:
20y-20y =0
so answer is 16x
Answer:
48
Step-by-step explanation:
Answer:
n > 13.7
Step-by-step explanation:
Writing a symbolic statement, we get:
n - 9.1 < 4.6
Multiplying all three terms by 10 removes fractions:
10n - 91 > 46
Adding 91 to both sides isolates the 10n term:
10n > 46 + 91, or 10n > 137
Then n > 137/10, or n > 13.7
