Answer:

92

Step-by-step explanation:

Angle (x+1) is equal to 92 degrees, and x equals 91. If x equals 91, then (x+1) equals 92. (x+1) and angle y are equal angles, so therefore, you can determine that angle y is equal to 92 degrees.

Step-by-step explanation:

Radius is half of the diameter.

Answer: x = 40

have: ∠A + ∠B + ∠C + ∠D = 180°

⇔ x + 6 + x + 4 + x +10 + x = 180°

⇔ 4x + 20 = 180

⇔ x = (180 - 20)/4

⇔ x = 160/4 = 40

Answer:

Step-by-step explanation:

For club 1 - 2 book

For club 2 - 4 books

Club 1 has a $40 fee + 2 books = $60 in total

Club 2 has a $0 fee + 4 book = $60 in total

I'm pretty sure I'm right

Answer:

There would have to be 2 books purchased from the first club. Then, there would have to be 4 books purchased from the second club.

Step-by-step explanation:

1st club.  (cost of club) 40$ + (cost of 2 books) 20$ = 60$.

2nd club. (cost of books) 15$ x  (how many books) 4 = 60$

Answer: Small box = $5

Large box = $14

Step-by-step explanation:

Let the cost of a small box be a

Let the cost of a large box be b

The scenario in the question can be modelled into an equation as:

3a + b = 29 ....... equation i

3a + 4b = 71 ....... equation ii

Subtract equation ii from equation I

-3b = -42

b = 42/3

b = 14

Cost of large box = $14

We put the value of b into equation I

3a + b = $29

3a + $14 = $29

3a = $29 - $14

3a = $15

a = $15/3

a = $5

Cost of small box = $5

Answer:

The slope is -3

Step-by-step explanation:

Find 2 points (-2,3) (-1,0) are 2.

Next subtract y 1 by y 2  in this example, 3-0 which equals 3

After that, subtract x 1 and x 2. In this example, -2-(-1) which equals -1.

Now dive y over x.  3/-1 or -3.

So the slope is -3.

Answer:

Answer:

x = - 6.22 or - 56/9

Step-by-step explanation:

Step 1:

34 + 12x = 3x - 22             Equation

Step 2:

12x = 3x - 56            Subtract 34 on both sides

Step 3:

9x = - 56          Subtract 3x on both sides

Step 4:

x = - 56 ÷ 9           Divide

Answer:

x = - 6.22

Step-by-step explanation:

First dicide what the problem is really asking you then you end up getting divisoin them divide 515/3.

Answer:

see explanation

Step-by-step explanation:

Since the triangles are congruent then corresponding sides are congruent, then

CA = NE , that is

4x + 3 = 11 ( subtract 3 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2

----------------------------------------

AR = EW, that is

4y - 12 = 10 ( add 12 to both sides )

4y = 22 ( divide both sides by 4 )

y = 5.5

-------------------------------------------

NW = x + y = 2 + 5.5 = 7.5

CR = NW = 7.5

Answer:

x = ± [tex]\sqrt{\frac{a^2b^2-a^2y^2}{b^2} }[/tex]

Step-by-step explanation:

Given

[tex]\frac{x^2}{a^2}[/tex] + [tex]\frac{y^2}{b^2}[/tex] = 1

Multiply through by a²b² to clear the fractions

b²x² + a²y² = a²b² ( subtract a²y² from both sides )

b²x² = a²b² - a²y² ( divide both sides by b² )

x² = [tex]\frac{a^2b^2-a^2y^2}{b^2}[/tex] ( take the square root of both sides )

x = ± [tex]\sqrt{\frac{a^2b^2-a^2y^2}{b^2} }[/tex]

In formula x²/a²+y²/b²=1

Value of  x as subject, x = ± [a√(b² - y²)]/b

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side.

Given equation,

x²/a² + y²/b² = 1

moving y²/b² to right side

x²/a² = 1 - y²/b²

multiplying a² on both sides

a². x²/a² = a². 1 - a². y²/b²

Simplifying

x² = a² - a²y²/b²

x = ± √(a² - a²y²/b²)

x = ± a√(1 - y²/b²)

x = ± [a√(b² - y²)]/b

Hence, value of x = ±[a√(b² - y²)]/b in formula x²/a² + y²/b² = 1

Answer:

288 hours

Step-by-step explanation:

So you have 24 per month. so month can be represented by x.

24x= y

Y is the amount of hours.

One year is 12 months. so plug 12 into x

24(12) =y

y= 288
