ElenaW [278]

Answer: 75 pages

Step-by-step explanation:

3/10 of 2/3

= 3/10 * 2/3  

= 2/10; simplified by dividing by 2 = 1/5

1/3 + 1/5 = 8/15

Let x represent the amount of pages left

so, 7/15 x = 35

x = 75

Therefore, there are 75 pages in the book

The mean (rounded to the nearest tenth if needed) of the following data set is: 30, 29, 40, 51, 39, 33, 24, 60, 40, 35, 58
bekas [8.4K]
Mean is just the average so to calculate the average just add up all the data and divide it by the number of data.
so it's gonna be
(30+29+40+51+39+33+24+60+40+35+58) / 11
= 39.9 (corrected to the nearest tenth)

Which point lies on the line with point-slope equation y - 3 = 4(x + 7)?
Sav [38]

Answer:

y=4x+31

your answer will have a line that

3 is your y-intercept located at your y-axis

and 4x your slope.

we start from our point on the y-axis 31

and rise/run

rise over run = 4/1

rise 4

run 1

so move up 4

and to the right 1

Step-by-step explanation:

Since there is no image for me to tell you which line it is you can easily find out by chancing this expression to y=mx+b form. also known as slope intercept form.

y-3=4(x+7)

we want to do order of operations. pemdas

so first we do Parenthesis to do so we need to distribute the 4.

after we do so we get...

y-3=4x+28

now we need to move -3 to isolate y

to do so we need add 3

y=4x+31
