Answer 1

Answer: The system of equations is

40x + 55y = 920

40x + 65y = 1000

x is the cost of the adult ticket; y is the cost of the child ticket

Step-by-step explanation:

If you have to solve this, elimination is a good method.

Subtract the top equation from the second equation.

40x + 65y = 1000

-40x + 55y = 920 x cancels Solve for y

0 + 10y = 80 Divide both sides by 10

y = 8 . Substitute 8 for y in either equation and solve for x

40x + 65(8) = 1000

40x + 520 = 1000 Subtract 520 from both sides

40x = 1000 - 520

40x = 480 Divide both sides by 40

x = 12

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°.

Old Farmer MacDonald wants to build a pen to keep his chickens in. He has 36 meters of fence and plans to make a rectangular pen. Complete the chart to help Old MacDonald decide how to make his chicken pen so that he has the maximum area.

Answers

Answer:

2 = 18

4 = 9

6 = 6

8 = 4.5

10 = 3.6

12 = 3

14 = 2.57 (2.6 simplified)

16 = 2.25 (2.3 simplified)

Step-by-step explanation:

You can solve this by dividing 36 (the whole amount of meter of fences)

by each number of the length

area width

36 divided by 2 = 18

36 divided by 4 = 9

36 divided by 6 = 6

36 divided by 8 = 4.5

36 divided by 10 = 3.6

36 divided by 12 = 3

36 divided by 14 = 2.57 (2.6 simplified)

36 divided by 16 = 2.25 (2.3 simplified)

A band must pay a $2500 entrance fee, It will split the cost between its 25 members. How much will each member pay?
Please help quick

Answers

Answer $100 each

Step-by-step explanation:

2500/25

Answer: 2500/25

Each member pays $100

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

Explanation:

The slash symbol means division. It's the same as saying 2500 ÷ 25

The expression 2500/25 simplifies to 100, which means that each member must pay $100. If you had 25 members paying $100 each, then 25*100 = 2500 dollars is the total amount of money paid.

So in short, you divide the total cost over the number of members.
