Sole x in the diagram 3x 75
Answers
Answer:
x=25
Step-by-step explanation:
Assuming you meant 3x = 75 what you want to do is isolate x. To isolate x you want to work backward. Since it is 3 times x you want to divide each side by 3 to get x on its own.
(3x)/3 = (75)/3
When you divide 3 and 3 you get one. 1x is represented by just an x so x=25.

17 units to the left of -6 on a number line is - 6 - 17 which equals to - 23.
What is a number line?
A number line is exactly what it sounds like a horizontal, straight line with numbers spaced evenly apart throughout its length. Since it's not a ruler, the distance between each number is irrelevant; instead, the numbers on the line specify how they should be used.
The given statement 17 units to the left of - 6 on a number line can be interpreted as,
We we'll start at - 6 on the number line, Now we know moving to the left horizontal direction in a number line results in subtraction.
Therefore, 17 units to the left of - 6 on a number line is,
= - 6 - 17.
= - 23 units from the origin which should be labeled at zero.

Stephanie ! I see that you tried to draw a picture, but you didn't get very far.
Can I tell you what this example wants you to practice ?
Three things:
Thing #1: Remember the formula for the area of a rectangle.
Area = (length) times (width) .
Thing #2: Changing mixed numbers to fractions, and
fractions to mixed numbers.
Thing #3: Multiplying fractions.
This sandbox is a rectangle.
Its length is 3-1/12 yards.
Its width is 2-3/4 yards.
What is its area ?
Area = (length) times (width) .
Area = (3-1/12 yards) x (2-3/4 yards) .
In order to multiply mixed numbers, you have to change them both to fractions.
-- Change 3-1/12 to a fraction
3 and 1/12 is 3 wholes and 1/12
Each whole is 12 / 12.
3 wholes = 36/12
plus one more = 37/12 .
-- Change 2 and 3/4 to a fraction.
2 and 3/4 is 2 wholes and 3/4
Each whole is 4/4 .
2 wholes are 8/4 .
plus three more = 11/4 .
There you are. Now you know the length and width
of the rectangle as fractions.
Length = 37/12
Width = 11/4
Area = (length) times (width)
Area = (37/12) times (11/4)
Do you remember how to multiply two fractions ?
==> Multiply the numerators to get the numerator.
==> Multiply the denominators to get the denominator.
(37/12) x (11/4)
= (37 x 11) / (12 x 4)
= (407) / (48)
That's it ! As an improper fraction, the area is
407/48 square yards.
Now ... do you remember how to change an improper fraction
to a mixed number ?
I won't tell you how. Please look back in your math book, or in
the handouts, or in the homework, or in the notes, and find
how to change an improper fraction to a mixed number.
I know it's been taught in your class ... otherwise you would
not get this problem where you have to use it.
407/48 = (8 and 23/48) square yards.
That's the answer, but DON'T stop there. The answer is
NOT important. The important thing is that YOU need to
understand HOW to FIND the answer. Once you understand
that, it doesn't matter if you have the answer or not.
