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

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)

I need help solving this equasion
Answers
130+x=180
X=50
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°.

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.
