Answer:

Step-by-step explanation:

The "trick" to this problem is knowing that opposite sides of the box add up to 180°

Now that you know that maybe you can solve this?

180= 7x+2 + 6x-4

180 = 13x -2

182 = 13x

14 = x

find y now to find all the angles

180 = 2y + 4 +4y - 4

180 = 6y

30 = y

now solve the x expressions and the y expressions

7x+2

7(14)+2

98 + 2

D= 100°

6x-4

6(14)-4

84-4

B = 80°

2y + 4

2(30) + 4

60 + 4

A = 64°

4y-4

4(30)-4

120-4

C = 116°

Answer:

The manager purchased 28 soccer balls.

Step-by-step explanation:

Since the information states that the athletic department manager purchased a total of 52 balls, you can say that the result of adding up the number of footballs and soccer balls purchased is 52, which can be expressed as:

x+y=52, where:

x is the number of footballs purchased

y is the number of soccer balls purchased

Also, as the statement indicates the price of each type of ball and the total cost, you can say that adding up the results of multiplying the price of each ball for the quantity purchased is equal to the total amount spent, which is:

23.53x+19.86y=1,120.80

Now, you have 2 equations:

x+y=52 (1)

23.53x+19.86y=1,120.80 (2)

To be able to find the value of x and y, first you can isolate x in (1):

x=52-y (3)

Then, you can replace (3) in (2) and solve for y:

23.53(52-y)+19.86y=1,120.80

1,223.56-23.53y+19.86y=1,120.80

1,223.56-1,120.80=23.53y-19.86y

102.76=3.67y

y=102.76/3.67

y=28

Finally, you can replace the value of y in (3) to find the value of x:

x=52-28

y=24

According to this, the answer is that the manager purchased 28 soccer balls.

Step-by-step explanation:

2x+5=3x-12

or, 2x-3x=5-12

or, -x= -7

i.e X=7

again

y+4=3x+2

or, y+4=3*7+2

or, y+4=21+2

or, y+4=23

or, y =23-4

i.e y = 19

hence, the value of X is 7 and y is 19

Answer:

(3x-7) (x+1)

Step-by-step explanation:

3x^2 - 4x - 7

First split the middle term

3x^2 + 3x - 7x - 7

Make into two separate expressions

(3x^2 + 3x) (-7x-7)

Take out what you can

3x (x+1) -7 (x+1)

Now you have your answers

(3x-7) (x+1)

Answer:

3/5

Step-by-step explanation:

The numerator, 24, and the denominator, 40, both have a GCF(greatest common factor) of 8. By dividing both the numerator, 24, and the denominator, 40, by 8 you would be simplify the fraction. In which you'd get a numerator of 3 and a denominator of 5, which is 3/5 and the simplest form of 24/40.

The simplified form of 24/40 is 3/5.

To simplify the fraction 24/40, we need to find the greatest common factor (GCF) of the numerator (24) and the denominator (40) and then divide both the numerator and denominator by that GCF.

The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, and 24.

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, and 40.

Looking at the lists of factors, we can see that the greatest common factor of 24 and 40 is 8.

To simplify the fraction, we divide both the numerator and denominator by 8:

24 ÷ 8 = 3

40 ÷ 8 = 5

Therefore, the simplified form of 24/40 is 3/5.

The simplified fraction represents the same proportion as the original fraction but is written in its simplest and most reduced form. In this case, 24/40 can be simplified to 3/5 by dividing both the numerator and denominator by their greatest common factor, which is 8.

Answer:

question what number is on the top or bottom of the parallelagram

Step-by-step explanation:

and what is on the left or right of the parallorgram I need to know to help you

The area of the parallelogram will be 98 square feet.

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

Let h be the perpendicular distance between the parallel side and b be the length of the base of the rectangle.

Then the area of the parallelogram will be given as,

Area of parallelogram = b x h

The length of the base of the parallelogram is 14 feet, and the value of h is 7 feet.

Then the area of the parallelogram will be

Area pf parallelogram = 14 x 7

Area pf parallelogram = 98 square feet

Then the area of the parallelogram will be 98 square feet.
