Damarcus and Xavier went to the arcade to play their two favorite games. Damarcus played 4 rounds of game 1 and 6 rounds of game 2 for $18.00. Xavier played 5 rounds of each game for $20. What is the cost of game 1? A. $1.00 B. $2.00 C. $3.00 D. $4.00

Answers

Answer 1

Answer:

The correct option is (c).

Step-by-step explanation:

Let x and y denote the cost of game 1 and game 2 respectively.

ATQ,

4x+6y = 18  ....(1)

5x + 5y = 20 ....(2)

Multiply equation (1) by 5 and equation (2) by 4.

20x+30y = 90 ....(3)

20x + 20y = 80 ....(4)

Subtracting equation (3) and (4)

20x+30y - (20x + 20y) = 90-80

20x-20x+30y-20y = 10

10y = 10

y = 1

Put the value of y in equation (1).

4x+6(1) = 18

4x = 18-6

4x = 12

x = 3

Hence, the cost of game 1 is $3.00

Answers

Answer and Step-by-step explanation:

For the triangles, all you have to do is subtract the two angles by 180 to find the missing angle.

2.

180 - 54 - 85 = 41

3.

180 - 36 - 59 = 85

4.

The square on the bottom represents a right angle, and right angles are always 90 degrees.

180 - 90 - 54 = 36

1: x = 47, y = 902: x = 92, y = 88, z = 923: 284: x = 90, y = 855: 133

Explanation:

[1] - A

y = 90 (90 degree angle)

90 - 43 = 47, so x = 47

[2] - C

x = 92 because 180 - 88 = 92

x = 92 and y = 88 because 92 + 88 = 180

[3] - C

x = 28 because 90 - 62 = 28

[4] - D

x = 90 because 180 - 90 = 90

y = 85 because 42 + 53 = 95, 180 - 95 = 85

[5] - A

x = 133 because 180 - 47 = 133
