Answer:

C

Step-by-step explanation:

Less Than or equal to is a closed circle so it would first need to be a closed circle. Then, use the arrow trick(which way is the back of the symbol pointing) in this case it is to the left, so it would be C.

Step-by-step explanation:

Answer:

75

Step-by-step explanation:

Given That :

Operation cost = $2250 per month

Purchase price per bike = $40

Average selling price per bike = $70

How many bicycles must the store sell each month to break even ;

Break even point = point at which there is net profit / loss = 0

Let number of bicycles store must sell = x

Operation cost + (purchase price * Number of bicycles) = selling price * Number of bicycles

2250 + 40x = 70x

2250 = 70x - 40x

2250 = 30x

x = 2250 / 30

x = 75

To break even 75 bicycles must be sold

Answer:

$27.93

Step-by-step explanation:

First we divided 4 from 15.96 and got 3.99, so now we know that $3.99 is how much each ounce of jellybeans costs so now we multiply 3.99 times 7 to get our answer of 27.93.

Answer:

x = 5°

Step-by-step explanation:

5x + 21° + 20x + 34° = 180°

25x + 55° = 180°

25x = 180° - 55°

25x = 125°

x = 125°/25

x = 5°

Hope you got it dear !!!!

Geometric relationship is supplementary angles. Supplementary angles sum up to 180 degrees.

The value of x is 5.

Thus:

[tex](5x + 21) + (20x + 34) = 180^{\circ}[/tex]  (angles on a straight line are supplementary)

[tex]5x + 21 + 20x + 34 = 180[/tex]

[tex]25x +55 = 180[/tex]

[tex]25x = 180 - 55\\\\25x = 125[/tex]

[tex]x = 5[/tex]

Answer:

7=7

Step-by-step explanation:

Simplify

7+37+3  to  1010.

7x=107x=10

Divide both sides by:

77 x={10}{7}x=  ​7  ​10

Let x=10/7x=   7 10/7 -3=77×  ​7  ​10

−3=7

Cancel 7:

10-3=710−3=7

Simplify

10-310−3  to  77.

I'm think that explicit formulas are like an = a1 +d(n - 1) and just replace the Variables with the correct numbers

Answer:

y = 62

Step-by-step explanation:

Since we need to solve for x first, we'll solve the left triangle first. A triangle equals 180 degrees, so with in mind:

x + 7 + 3x - 18 + x - 9 = 180

add like terms

5x - 20 = 180

add 20 to both sides

5x = 200

divide by 5

x = 40

Now we have x, input it into the equations for the second triangles:

x + 21 + x + 17 + y = 180

40 + 21 + 40 + 17 + y = 180

add/simplify

118 + y = 180

subtract 118 from both sides

y = 62

Answer:

x = 40° ; y = 62°

Step-by-step explanation:

The figure consists of 2 triangles. According to Angle sum property in a triangle , sum of measure of all the angles of a traingle is equal to 180° .

So ,

[tex](3x - 18) + (x + 7) + (x - 9) = 180[/tex]

[tex] = > 5x - 20 = 180[/tex]

[tex] = > 5x = 180 + 20 = 200[/tex]

[tex] = > x = \frac{200}{5} = 40[/tex]

Now using the angle sum property in another triangle ,

[tex](x + 21) + (x + 17) + y = 180[/tex]

[tex] = > y + (40 + 21) + (40 + 17) = 180[/tex]

[tex] = > y + 61 + 57 = 180[/tex]

[tex] = > y + 118 = 180[/tex]

[tex] = > y = 180 - 118 = 62[/tex]

Answer:

1 is correct

2 is correct

3 is incorrect

4 is incorrect

5 is correct

Step-by-step explanation:

1 is correct because the statue lies the same distance from both entrances.

2 is correct because B is also the same distance from both entrances.

3 is the opposite of 2, saying that B is not equal distance from both entrances, making it false.

4 is incorrect because a is closer to the upper entrance.

5 is correct because it is basically the same question as 2, saying b is the same distance from both entrances.

Answer:10 inches

Step-by-step explanation: 4+4+1+1=10The perimeter of a rectangle is the sum total length of all of its sides.[1] A rectangle is defined as a quadrilateral, or a geometric shape with four sides. In a rectangle, both sets of opposite sides are congruent, meaning that they are the same length.[2] While not all rectangles are squares, all squares can be considered rectangles, and a compound shape may be composed of rectangles.[3]

Answer:

y = 3/x

Step-by-step explanation:

Answer:

y=10 when x=7

Step-by-step explanation:

y=2x-4

y=10

Substitute y with "10": 10=2x-4

Add 4 on both sides: 14=2x

x=7

Answer:

substitute 10 for y in the equation y=2x-4

10=2x-4

2x=10+4

2x=6

divide both side by 2

x=3

Answer:

x = 10

Step-by-step explanation:

It's given in the question that both the traingles JCD & JKL are similar. So their ratio of corresponding similar sides will be proportional to each other.

[tex] = > \frac{JD}{JL} = \frac{JC}{JK} = \frac{DC}{LK} [/tex]

[tex] = > \frac{15}{50} = \frac{8 + x}{60} = \frac{DC}{LK} [/tex]

[tex] = > \frac{15}{50} = \frac{8 + x}{60} [/tex]

[tex] = > 8 + x = \frac{15 \times 60}{50} = 18[/tex]

[tex] = > x = 18 - 8 = 10[/tex]
