A girl read a book that had 1,159 pages. She read 72 pages on the first day. She then read 40 pages per day until she finished the book. Which equation could be used to find the number of days, d, it took her to read the book?

Answer:

Step-by-step explanation:

f(x)=x*3+4-2

f(3)  =   11     3*3+4-2

f(2)=8                2*3+4-2

f(9)=29         9*3+4-2

The unit rates of   y = –2x is -2, for y = 0.75x the unit rate is 0.75, for 2y = 9x then the unit rate is 4.5 and for  equation –4y = 18x the unit rate is -4.5

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Unit rate is the ratio of two different units, with denominator as 1.

For  y = –2x then the unit rate is -2

For y = 0.75x then the unit rate is 0.75

For 2y = 9x then the unit rate is 9/2 or 4.5

For –4y = 18x then the unit rate is -18/4 or -4.5

Hence, the unit rates of   y = –2x is -2, for y = 0.75x the unit rate is 0.75, for  2y = 9x then the unit rate is 4.5 and for  –4y = 18x the  unit rate is -4.5

Answer:

x-3 _< 14

Step-by-step explanation:

Hence, the equation is of the form

[tex]x-3\leq 14[/tex]

What is the inequality?

An inequality is said to be sharp if it cannot be relaxed and still be valid in general.

Here given that,

With new batteries, Jayce's camping flashlight can work for up to [tex]14[/tex] hours before it runs out of power. He just put new batteries in and has already used the flashlight for [tex]3[/tex] hours.

Let x represent how many more hours Jayce can use his flashlight before running out of power

So, the equation is of the form

[tex]x-3\leq 14[/tex]

Hence, the equation is of the form

[tex]x-3\leq 14[/tex]

Answer:

25%

Step-by-step explanation:

The first step is to divide 5 by 20 to get the answer in decimal form:

5 / 20 = 0.2500

Then, multiply the answer from the first step by one hundred to get the answer as a percentage:

0.2500 * 100 = 25.00%

Answer: 25%

Step-by-step explanation: since 5x4 is 20, 5 is one quarter of 20 which is 1/4 or 25%

Answer:

Im pretty sure the answer is c

Answer:

1) D.208

2) C.112

Step-by-step explanation:

so basically for 1 you solve the area for all the shapes you see in the net using the equation l*w=a and add them together

l= length

w=width

a=area

4*8=32

4*8=32

6*4=24

6*4=24

6*8=48

6*8=48

48+48+24+24+32+32=208

208[tex]cm^{2}[/tex]

for number 2 since it's lateral surface area, you wanna find the area of all the shape in the net except for the square in the middle.

for the triangles you're gonna wanna use the equation 1/2b*h=a

b= base

h=height

a=area

Answer:

50 degrees

Step-by-step explanation:

The angles of a triangle add up to 180 degrees. We would set up the equation like this:

2x+18 + 4x+11 + 55 = 180

Combine like terms:

6x + 84 = 180

Solve for x:

6x = 96

x = 16

We substitute 16 back in for x and see the measure of the smallest angle.

2(16)+18 = 50

4(16)+11 = 75

55

The smallest angle here in 50 degrees.

Answer:

2x + 18 = 50

Step-by-step explanation:

2x + 18 + 4x + 11 + 55 = 180

6x + 84 = 180

180 - 84 = 96

6x = 96

96/6 = 16

x = 16

2(16) + 18 = 50

55

4(16) + 11 = 75

The constant of proportionality is 3.

Step-by-step explanation:

Constant of proportionality is found by doing k = [tex]\frac{y}{x}[/tex]. Point (2,6) is on the line, so if we plug in point (2, 6) into the equation to solve for the constant of proportionality, we get [tex]k=\frac{6}{2}[/tex] or k = 3. The constant of proportionality is 3.
