The ratio of ebooks to novels is 4:5. if there are 32 ebooks how many novels are there?

Answers

Answer:  40 novels

================================================

Work Shown:

n = number of novels

(32 ebooks)/(n novels) = 4/5

32/n = 4/5

32*5 = n*4 ............ cross multiply

160 = 4n

4n = 160

n = 160/4 .............. dividing both sides by 4

n = 40

There are 40 novels.

15(2x+2)=10(3x+4) equations with special cases

Answers

Answer:

no solution

Step-by-step explanation:

15(2x+2)=10(3x+4)  Distribute.

30x+30=30x+40     Subtract 30x from both sides.

-30x       -30x

30=40

30 does not equal 40, so there is no solution.

Hope this helps!! Have a great day C:

I need help solving this equasion

Answers

70+60+x=180
130+x=180
X=50
Angles 60°, 70° and y form a straight line.
Angle on a straight line is 180°
So to get y it will be 180°-(60°+70)
Which is equal to 180°-130°= 50°
Y= 50°
Y and x are vertically opposite angles and vertically opposite angles are equal so therefore x=y and y=50° so x is also equal to 50° or also to find x you could do the same method as the way to find y. Angles 60°, 70° and x form a straight line. So 180°- (60°+70°)= 180°-130°=50°
X=50°.

Find the value of x. Your answer must be exact.
х
45° 18

Answers

Answer:

x = 63

Step-by-step explanation:

Simplifying

x + -18 = 45

Reorder the terms:

-18 + x = 45

Solving

-18 + x = 45

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '18' to each side of the equation.

-18 + 18 + x = 45 + 18

Combine like terms: -18 + 18 = 0

0 + x = 45 + 18

x = 45 + 18

Combine like terms: 45 + 18 = 63

x = 63

Simplifying

x = 63

The slope of the line below is 5. Which of the following is the point-slope form
of the line?
(-1,3)
5
A. y + 3 = -5(x - 1)
B. y + 3 = 5(x - 1)
C. y - 3 = 5(x+1)
D. Y-3 = -5(x + 1)

Answers

The point-slope form of the line in the graph is y-3 = 5(x+1). The correct option is C.

What is the point-slope form of the line?

The point-slope form of the line is y-y₁ = m( x-x₁)

Here, m is the slope of the line.

The graph given in the question has a slope of 5

It passes through the point ( -1,3)

The point slope form of the line is

y - 3 = 5 ( x - (-1))

y-3 = 5(x+1)

This is represented by option C.
