Answer:
4 ft 11 inches
Step-by-step explanation:
Remember that 12 inches is 1 foot, so 24 inches is 2 feet. That means, 23 inches is 1 foot 11 inches. 11/12 is one inch gone from a foot, so 23/24 much be one inch gone from 2 feet.
Since you already have 3 feet, adding the 1 foot and 11 inches leaves you with 4 ft 11 inches as a result.
Answer:
False
Step-by-step explanation:
This is false because 1 meter has 36 inches.
An easy way to do this is by using the simplest equations you can:
x + y and x - y
(3, 5) is (x, y). all you have to do is plug those into your equations and get a result, so:
x + y = 8
(because 3 + 5 = 8)
x - y = -2
(because 3 - 5 = -2)
and those can serve as your system of equations.
you can check it by solving by substitution:
x - y = -2
x + y = 8
solve one of the equations for a single variable:
x = y - 2
plug it into the second equation:
(y - 2) + y = 8
y - 2 + y = 8
2y - 2 = 8
2y = 10
y = 5
then plug that result back into the equation:
x + y = 8
x + 5 = 8
x = 3
