Brenda had $23 to spend on two notebooks. After buying them she had $19. How much was each notebook?

Answer:

10/3

Step-by-step explanation:

15+2w=5w+5

15=5w-2w+5

15=3w+5

3w=15-5

3w=10

w=10/3

Answer:

10/3=w

Step-by-step explanation:

15+2w = 5w+5

15=3w+5

10=3w

10/3=w

Answer:

S= 15W

Step-by-step explanation:

Im not good at explaing, but if you move forward three units and up 6, then draw a point, then go forward to 5 units and down to one unit and connect those dots, the line would be going down to the right

Answer:

The measures of the two angles are 55 and 100 degrees.

Step-by-step explanation:

The three interior angles of a triangle always add up to 180.

So if one angle is 25 degrees

180 - 25 = 155

The two other angles must add up to 155.

If the ratio is 11:20

That means there are 31 equal parts between the two angles

So 155/31 =5

Whic means

11 x 5 = 55

20 x 5 = 100

The two missing angles are 55 and 100 degrees.

Hope this explanation helped you!

Step-by-step explanation:

Answer:

slope = [tex]-\frac{3}{4}[/tex]

Step-by-step explanation:

1) To find the slope between a pair of points, use the slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

[tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through. [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line also passes through. We know the line passes through (-4,5) and (0,2). So, substitute their x and y values for the formula (following the appropriate order) and solve:

[tex]\frac{(2)-(5)}{(0)-(-4)} \\= \frac{2-5}{0+4} \\= \frac{-3}{4}[/tex]

Thus, the slope is [tex]-\frac{3}{4}[/tex]

Answer:

  cos(θ) = (5√74)/74

Step-by-step explanation:

The length of the hypotenuse is given by the Pythagorean theorem:

  h = √(5² +7²) = √74

The cosine of the angle is the ratio of the adjacent leg to the hypotenuse:

  cos(θ) = 5/√74 = (5√74)/74

Answer:

(7.46-2.66)/5 do that and you have the answer (I'm lazy)

Step-by-step explanation:

The equation for jj is ($7.46 - $2.66) / 5 and the cost of each bottle of juice is $0.96

The first step to take in order to determine jj, is to determine the total cost of the  5-pack of juice bottles.

Cost of the  5-pack of juice bottles = Total cost before tax - cost of the bag of oranges

Cost of the  5-pack of juice bottles = $7.46 - $2.66 = $4.80

The second step is to determine the cost of each bottle of juice

The cost of each bottle of juice = Cost of the  5-pack of juice bottles / total number of bottles

$4.80 / 5

= $0.96

The previous steps can be summarized into this equation :

The cost of each bottle of juice = (Total cost before tax - cost of the bag of oranges) / total number of bottles

= ($7.46 - $2.66) / 5

= $0.96

Answer:

angles 1 and 6

Step-by-step explanation:

Vertical angles because they share the same Vertex.

One pair of vertical angles in the figure from the options is ∠1 and ∠6.

Vertical angles are angles that are opposite each other at the intersection of two lines. They are also called vertically opposite angles or non-adjacent angles with the same vertex. They have the same angle measurement or size.

Given is a figure, we need to determine the vertical angles in that,

The vertical angles are -

∠2 and ∠5

∠3 and ∠8

∠7 and ∠4

Hence, one pair of vertical angles in the figure from the options is ∠1 and ∠6.

Step-by-step explanation:

2(7x - 4)

Multiply 2 × 7x = 14x

Multiply 2 × 4 = 8

Put together to get 14x - 8

Answer:

Step-by-step explanation:

lets solve the problem 7x+2=3x+10

subtract 3x from 7x

4x+2=10

subtract 2 from 10

4x=8

divide both sides by 4

x=2

to find VU plug in 2 for x so...

3(2)+10

6+10

16

I hope this helped you :)

Step-by-step explanation:

7x + 2 = 3x + 10

7x - 3x + 2 = 3x - 3x + 10

4x + 2 = 10

4x + 2 - 2 = 10 - 2

4x = 8

4x ÷ 4 = 8 ÷ 4

x = 2

VU = 3x + 10

VU = 3(2) + 10

VU = 6 + 10

VU = 16

Answer:

B) x = 20

Step-by-step explanation:

The formula for finding the missing side of a right triangle is: a^2+b^2=c^2.

C represents the longest side of the right triangle, so if we plug in the given lengths, we can solve: 12^2 + 16^2 = x^2

Solve the exponents: 144 + 256 = x^2

Add: 400 = x^2

Find the square root: 20 = x

Answer:

x=7

Step-by-step explanation:

Let's solve your equation step-by-step.

5x+3−2x=24

Step 1: Simplify both sides of the equation.

5x+3−2x=24

5x+3+−2x=24

(5x+−2x)+(3)=24(Combine Like Terms)

3x+3=24

3x+3=24

Step 2: Subtract 3 from both sides.

3x+3−3=24−3

3x=21

Step 3: Divide both sides by 3.

Answer: x=7

Step-by-step explanation:

Given

5x + 3 - 2x = 24

Subtract both sides by 3

5x + 3 - 3 - 2x = 24 - 3

5x - 2x = 21

Simplify

3x = 21

Divide both sides by 3

3x / 3 = 21 / 3

x=7

The y axis is the vertical line. b is y intercept, meaning where the line crosses the y axis. here b is 2, so plot a point on (0,2). m is the slope. slope is rise/run, and your slope is -1/2. this means your rise is negative one, (go down one) and you run is positive two (go two to the right) and plot your point. then you connect this point to the first point and extend the line on both sides. hope this helps :)

Answer:

Initial value = 10, slope = 4

Step-by-step explanation:

Initial value is the point where x takes its lowest value. In this case it is x = 0 and y = 10. Rate of change is the slope at a given point. Because this is a first order equation graph the slope is always the same. And in this case it is 4 as for every 1 unit of x the y goes 4.
