Answer
not sure but 1 : 21
Step-by-step explanation:
Change values to whole numbers.
Convert the whole number 9 to a fraction with 1 in the denominator.
We then have:
3/7 : 9 = 3/7 : 9/1
Convert fractions to integers by eliminating the denominators.
Our two fractions have unlike denominators so we find the Least Common Denominator and rewrite our fractions as necessary with the common denominator
LCD(3/7, 9/1) = 7
We now have:
3/7 : 9 = 3/7 : 63/7
Our two fractions now have like denominators so we can multiply both by 7 to eliminate the denominators.
We then have:
3/7 : 9 = 3 : 63
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 3 and 63 is 3
Divide both terms by the GCF, 3:
3 ÷ 3 = 1
63 ÷ 3 = 21
The ratio 3 : 63 can be reduced to lowest terms by dividing both terms by the GCF = 3 :
3 : 63 = 1 : 21
Therefore:
3/7 : 9 = 1 : 21
Answer:
166.75
Step-by-step explanation:
Answer:
$148
Step-by-step explanation:
We are given the expression:
48+25h
We are also given h=4. Since we know what h is equal to, we can substitute 4 in for h.
48 + 25h (h=4)
48 + 25(4)
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
First, multiply 25 and 4.
48+ (25*4)
48+100
Next, add 48 and 100
48+100

Answer:
The standard form of the equation for this line can be:
l: 2x + 5y = -15.
Step-by-step explanation:
Start by finding the slope of this line.
For a line that goes through the two points and ,
.
For this line,
.
Find the slope-point form of this line's equation using
- , and
- The point (using the point should also work.)
The slope-point form of the equation of a line
- with slope and
- point
should be .
For this line,
The equation in slope-point form will be
.
The standard form of the equation of a line in a cartesian plane is
where
, , and are integers. .
Multiply both sides of the slope-point form equation of this line by :
.
Add to both sides of the equation:
.
Therefore, the equation of this line in standard form is .
