Book a has 24 more pages than book b.book c has 4 times as many pages as book a.the total number of pages of the three books is 180.how many pages does book b have ?please show the work

Answers

Answer 1
Answer: a=b+24
c=4a
b=a-24
a+b+c=180
sub in a,b and c into a+b+c=180
b+24+4a+a-24=180
b+5a=180
sub a=b+24
b+5(b+24)=180
b+5b+120=180
6b=180-120
6b=60
b=10
Book B has 10 pages
Answer 2
Answer: a=24+b
c=4a
c=4(24+b)
a+b+c=180
24+b+b+4(24+b)=180
24+b+b+96+4b=180
120+6b=180
6b=60
b=10
a=24+10
a=34
c=4(34)
c=136
34+10+136=180
So book a has 34 pages, book b has 10 pages, and book c has 136 pages.

What is the substitution method?

A ball is thrown upward off of a 100 meter cliff with an initial velocity of 6 m/s. The function f(x)=-5x2+6x+100 (graphed below) represents this situation where x is time and y is the distance off of the ground.e. What would the new function be? What kind of transformation is this?
f. Would you still use the same domain and range? Why or why not?

Answer:

a) The domain of the function is    . , , b)The range of the function is . , , c) The ball is 73 meters off of the ground at x = 3 seconds.Step-by-step explanation:The complete statement is: A ball is thrown upward off of a 100 meter cliff with an initial velocity of 6 m/s. The function represents this situation where x is time and y is the distance off of the ground. a) What domain does the function make sense? b) What range does the function make sense ? c) How far off the ground is the ball at time x = 3 seconds?a) Let  and  be the time, measured in seconds, and the distance of the ground, measured in meters, respectively. Time is a positive variable, so domain corresponds to the interval when  and . That is: Therefore, the domain of the function is    . , b) The distance off of the ground is also a positive variable, where ball is thrown upward at a height of 100 meters and hits the ground at a height of 0 meters. Hence, the range of the function is . , c) The distance of the ball off of the ground at x = 3 seconds is found by evaluating the function:The ball is 73 meters off of the ground at x = 3 seconds.

Answer:

P * 300000 = 30

.01%

Step-by-step explanation:

Let P equal the percent.  Of means multiply and is means equals

We need to make sure the units are the same.  I will convert km to cm

3 km *1000m/1km  * 100cm/1m =300000 cm

Now we can write the equation

P * 300000 = 30

Divide each side by 300000

P 300000/300000 = 30/300000

P =.0001

Changing this from decimal to percent

P = .0001*100 = .01 %

Given B is the midpoint of AC, what is AC ?

A. 54
B. 27
C. 6
D. 18

Answers

A. 54

The fact that B is the midpoint means that AB = BC so you can set up the equation of
4x+3 = 3x+9

Then solve for x by subtracting 3 from the left and 3x from the right to get

X=6

Finally, plug that back in to your line and solve for the total value

4(6) + 3 + 3(6) +9 = 54
