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:

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

Step-by-step explanation:

You have given angle x and the hypotenuse you are asked to find the adjacent side of the triangle so you would be using

Cosθ = Adjacent/hypotenuse.

cos49 = adjacent/4

1.32 = adjacent/4

2.62 = adjacent

VX = 2.6

imagine you're in a queue to the airport check-in desk if two-thirds of the queue is in front of you and three tenths of the queue is behind you how many people are in the queue​

Answers

2/3 in front x10

20/30 In front
9/30 behind

20/30+9/30= 29/30
30 people are in the queue

Step-by-step explanation:

Let x be the number of people in the queue, including yourself.

We have 2/3 x + 1 + 3/10 x = x.

=> 29/30 x + 1 = x

=> x/30 = 1

=> x = 30.

Hence there are 30 people in the queue.

Solve the inequality:
16 < -2(x + 4)

Answers

Answer:

x < -12

General Formulas and Concepts:

Pre-Algebra

Distributive Property

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

16 < -2(x + 4)

Step 2: Solve for x

Distribute -2:                          16 < -2x - 8Add 8 to both sides:             24 < -2xDivide -2 on both sides:       -12 > xRewrite:                                 x < -12

Here we see that any number x smaller than -12 would work as a solution to the inequality.

4s-28=4

Answers

Answer: s = 8

Step-by-step explanation:

Add 28 to both sides of the equation

4s - 28 + 28 = 4 + 28

Then simplify

4s = 32

Divide both sides of the equation by the same term

4s = 32

4s/4 = 32/4

Simplify again

s = 8

Solution

s = 8

Answer:

  y +2 = (1/4)(x +1)

Step-by-step explanation:

The given line is in slope-intercept form:

  y = mx + b

where the slope (m) is -4 and the y-intercept (b) is +13.

For the perpendicular line, we need a slope that is the opposite reciprocal, or ...

  -1/m = -1/(-4) = 1/4

A suitable form for the desired equation is the point-slope form:

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

For m=1/4 and (h, k) = (-1, -2), the equation of the line is ...

  y +2 = (1/4)(x +1)

Step-by-step explanation:

Solve this system of equations by graphing. First graph the equations, and then type the solution. y=2x+2 y=x–2

Solution:

The equation of a straight line is in the form y = mx + b, where m is the slope of the graph and b is the y intercept (value of y when x = 0). To graph the line, online geogebra graphing calculator was used for plotting the two graphs by writing the equation of the graphs.

After plotting the two graphs, the intersection of the two lines should be traced to get the x coordinate and y coordinate of the point. This point is the solution of the two graph equations, hence:

The solution = (-4, -6)
