8(2.54) = 20.32
All you have to do is multiply how many inches there are by 2.54 centimeters to find out how many centimeters a given number of inches is equal to.
Answer:
0
Step-by-step explanation:
Answer:
(x + 8) / 4 = (x - 3) / 2 | *4
x + 8 = 2 * (x - 3)
x + 8 = 2 * x - 6
8 = x - 6
14 = x
The number is 14.
(14 + 8) / 4 = (14 - 3) / 2
22 / 4 = 11 / 2
5.5 = 5.5
Substitution Method:
3x - 10 = 2x - 5
3x = 2x + 5
x = 5
Now solving for y:
y = 3x - 10
y = 3(5) - 10
y = 15 - 10
y = 5
(x, y) = (5, 5)
Check answer:
5 = 3(5) - 10
5 = 15 - 10
5 = 5
5 = 2(5) - 5
5 = 10 - 5
5 = 5
Since all of the equalities are true, (5, 5) is a true solution
You can use models to estimate percent questions by estimating the locations of 50%, 75%, 40%, 6%, and 65% on the model..
