Three books cost $18.75. How much would 8 books cost?
Answers
Answer:
$50
Step-by-step explanation:
Create a proportion where x is the cost of 8 books:
[tex]\frac{3}{18.75}[/tex] = [tex]\frac{8}{x}[/tex]
Cross multiply and solve for x:
3x = 150
x = 50
So, 8 books would cost $50
Answer: $50
Step-by-step explanation:
$18.75 divided by 3 = $6.25
$6.25 times 8 = $50

An equation for the line whose slope is 5 and which passes through the point ( –2, 11)
Answers
substitute in the equation with the point that is given to get the y intercept, so :
11=5(-2)+b
11=-10+b
21=b
since the slope is 5 and the y intercept is 21, so the equation will be :
y=5x+21
hope this helps !
The required equation of the line whose slope is 5 and passes through the point (-2, 11) is (y - 11) = 5(x+2) or y = 5x + 21.
An equation for the line whose slope is 5 and which passes through the point ( –2, 11) is to determined.
A line can be defined by the shortest distance between two points is called a line. The standard equation of the line is y =mx + c, where m and c are the slope and y-intercept of the line respectively.
Slope ( m ) = 5 and an ordered pair ( -2 , 11 ) is given in question
Equation of line is given as
[tex]y-y_1= m(x-x_1)\\[/tex]
y - 11 = 5 (x + 2)
y - 11 = 5x + 10
y = 5x + 10 +11
y = 5x + 21
Thus, the required equation of the line whose slope is 5 and passes through the point (-2, 11) is (y - 11) = 5(x+2) or y = 5x + 21.

12 1/2 - 9 1/4= What is the answer to this question?
Answers
Answer:
3 1/4
Step-by-step explanation:
First you would convert them to improper fractions with common denominators.
12 1/2 >>>> 25/2
9 1/4 >>>>>> 37/4
to get a common denominator, you would multiply 25/2 by 1/2 to get 50/4.
50 - 37 = 13
so your answer would be 13/4

If you rewrote these percents as fractions which one could be written as a whole number over 10? A. 1% B. 5% C.25% D. 40%
Answers
Answer:
D. 40%
Step-by-step explanation:
Hi! All you basically need to do in this question is to really think. The tenths placement is what you are looking for.
Let us use money for example. a penny would represent 1%. It needs to be in tenths, 1/10, 2/10, 3/10, and so on to be a whole number. A penny is simplified to be only 1/100. This will not work.
B is 5%. This would represent a nickel. A nickel is simplified to be 1/20. This will not work. C is 25%. This would represent a quarter.
A quarter simplified is 2.5/10... not a whole number.
However 40% is 4/10, making it our answer.
Hope this helps!
