Step-by-step explanation:
When Dividing fractions, use the reciprocal of 3/4
7 1/2 times 4/3 equals
10
Answer:
10
Step-by-step explanation:
You would do something called KCF Keep, Change, and Flip.
You would keep the 7 1/2 and change the divided sign to multiplying sign and flip the 3/4 so its a 4/3 and then multiply it.
15/6 times 4/3. 15 x 4 = 60
2x3= 6
so I can be 60/6 but you would simplify and 6 goes into 60 10 times. so 10 is you answer

Dividing fractions
1 ÷ 1/10
Steps
Change the whole number which is 1 into a fraction.
1/1 ÷1/10
Flip the second fraction in the equation.
1/1 ÷ 10/1
Then change the division sign to a multiplication sign. So were multiply instead.
1/1 × 10/1
Multiply the fractions and your answer should be 10/1 .
This fraction is also changed to a whole number.

Select Proportional or Not Proportional to correctly classify each pair of ratios.
Proportional or Not Proportional
12 over 30 and 18 over 45
Step-by-step explanation:
Given that,
12 over 30 and 18 over 45
We need to tell whether the ratios are Proportional or Not Proportional.
[tex]\dfrac{12}{30}=\dfrac{2}{5}[/tex]
And
[tex]\dfrac{18}{45}=\dfrac{2}{5}[/tex]
The ratio for both fraction is same i.e. 2/5 Hence, each ratios are Proportional.
A college surveys local businesses about the importance of students as customers. The college chooses 150 businesses at random from telephone listings. Of these 68 return the questionnaire as a percent what is the proportion of businesses who did not respond
Answer: The proportion of businesses who did not respond = 54.67%
Step-by-step explanation:
Given : Total businesses = 150
Businesses responded = 68
Businesses did not respond = 150- 68 = 82
The proportion of businesses who did not respond =
[tex]\dfrac{\text{Businesses did not respond}}{\text{Total businesses}}\times100[/tex]
[tex]=\dfrac{82}{150}\times100=54.67\%[/tex]
Hence, the proportion of businesses who did not respond = 54.67%

Write an equation for a line that is parallel to y = -3x – 5 that goes through the point (-1, 8)
Answer:
y = -3x +5
Step-by-step explanation:
Parallel means that both slopes are the same.
This gives us y = -3x + C so far.
To find the y-intercept, we need to get x to 0.
Since we know the point (-1, 8), we can plug the number in into our equation
y = -3x + C.
8 = -3(-1) + C
8 = 3 + C
8 - 3 = C
5 = C or C = 5.
Now plug in C into our unsolved equation to get y = -3x +5.

2x+2y=16
Standard to slope intercept form.
The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
The equation 2x + 2y = 16 in slope-intercept form is
y = -x + 8.
Where slope = -1 and y-intercept is 8
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
We have the equation as,
2x + 2y = 16
We need to convert in the form of y = mx + c.
Subtract 2x on both sides.
2y = -2x + 16
Divide both sides by 2.
y = (-2x + 16) / 2
y = -x + 8
This is in the form of slope-intercept form.
Where slope = -1 and y-intercept is 8
Thus,
The equation 2x + 2y = 16 in slope-intercept form is
y = -x + 8.
Where slope = -1 and y-intercept is 8
