Complete Question
Marisa painted one-half of her bedroom in three-fourths of an hour. At this rate, how long would it take her to paint the entire room? three-eighths of an hour eight-thirds of an hour four-sixths of an hour six-fourths of an hour
Answer:
six-fourths of an hour
Step-by-step explanation:
Let her entire room be equal to 1
From the above question
1/2 of her bedroom = 3/4 of an hour
1(Entire bedroom) = x hour
Cross Multiply
1/2 × x = 3/4 × 1
x = 3/4 / 1/2
x = 3/4 ÷ 1/2
x = 3/4 × 2/1
x = 6/4 hour
Hence, it would take Marissa six-fourths(6/4) of an hour to clean her entire room.
This is so easy that it's confusing, and NOBODY ever gets it right
the first time they see it.
Inside the parentheses are two numbers. The first number is a value
for 'x', and the second number is a value for 'y', and they have to be
numbers that when you put them into the equation in place of 'x' and 'y',
the equation becomes a true statement.
In this problem, you already know what 'x' is ... it's -1 . Now, can you find
a value for 'y' that makes the equation true ?
Let me ask you that question again. It's <em>very, very important</em>:
The equation is . . . . . <em>Y = 8</em> . . . . . Can you find a value for 'y' that makes
this equation a true statement ?
Do you give up ?
Well, how about ' 8 ' ?
If you put ' 8 ' in place of 'y' in the equation, then the equation says . . . 8 = 8 . . . and that's true !
In fact, if you put <u>any other number</u> except '8' in place of 'y', then the
equation is <em>not </em>true. 'Y' must be 8 . It doesn't matter what 'x' is.
'X' is not even in the equation. It has no effect on 'y'.
'X' and 'y' don't even know about each other. They're not related in
any way, and nobody cares what 'x' is.
'Y' is ALWAYS 8 ... that's exactly what the equation is telling you . . . <em>Y = 8</em> .
