GrogVix [38]

Answer:

x=23

Step-by-step explanation:

let's make this question into equation form

x increase by 10; or x+10

is equal to 33; or =33

so it would look like this; x+10=33

now we can solve it in reverse

<em>33-10=23</em> so x is 23.

hope this helped, have a great day.

Please help!!<br><br> Find the x.
maw [93]

Answer:

10

Step-by-step explanation:

1. Write an equation to represent the ratio of the sides to the corresponding sides in the second figure.

6/9 = x/15

6 and x are both numerators because they are corresponding sides and 9 and 15 are both numerators because they are corresponding sides.

2. Solve for x.

multiply both sides by 9

6 = 9x/15

multiply both sides by 15

90 = 9x

solve for x by dividing both sides by 9

x = 10

*sorry if the explanation was confusing but I hope you understand with the equation and numbers

PLEASE HELP
Papessa [141]

Answer:

A)3.74

B)17.04

C)61.92

Step-by-step explanation:

The equation of the line of best fit:

y=3.74x+17.04

Where x is time in hours

y = midterm score

a)For an increase of one hour in the time spent studying,  what is the predicted increase in the midterm score?

General equation y = mx+c

where m is the slope .

On comparing m = 3.74

Slope is the rate of increase per hour

So, For an increase of one hour in the time spent studying,  the predicted increase in the midterm score is 3.74

b)What is the predicted midterm score for a student who  doesn't spend any time studying?

Substitute x = 0

y=3.74x+17.04

y=3.74(0)+17.04

y=17.04

c)What is the predicted midterm score for a student who  studies for 12 hours?

Substitute x = 12

So,y=3.74x+17.04

y=3.74(12)+17.04

y=61.92
