Three game tickets and four ride tickets cost $39. Five ride tickets cost $15. All game tickets cost the same and all ride tickets cost the same. What is the ratio of the cost of a game ticket to the cost of a ride ticket?

Answers

Answer: 3:1

Step-by-step explanation:

Let the cost of a game ticket be g.

Let the cost of a ride ticket be r.

The information given can be formed into an equation which will be:

3g + 4r = 39

Since Five ride tickets cost $15, the cost of each ride ticket will be:

= $15/5

= $3.

Therefore, 3g + 4r = 39

We put the value of r = $3 into the equation

3g + 4(3) = 39

3g + 12 = 39

3g = 39 - 12

3g = 27

g = 27/3

g = 9

The cost of a game ticket is $9

The ratio of the cost of a game ticket to the cost of a ride ticket will be:

= 9/3

= 3/1

= 3:1

The ratio is 3:1

Answers

Answer:

About 525 times.

Step-by-step explanation:

You have a 5 in 8 chance of getting a consonant originally. You should try to find an equal ratio except with 840 as the second number. As of now it's      5/8 = ?/840

8 is a factor of 840 and if you divide 840 by 8 you get 105. If you actually think about it 105/840 would be an equal ratio to 1/8 so you multiply 108 by 5 to get 525.

I agree with Jamal because Reggie was doing subtract a positive by a positive but the question is a positive minus a negative, by doing absolute value you can see they both have the same value just inverse so in this case the answer would be a positive

Step-by-step explanation:

these angles will add to 90 deg

90 = 22 + 2x

solve for x

Answer:

x = 34°

2x = 68°

Step-by-step explanation:

Both angles are complementary (add up to the sum of 90°), so we can say;

22 + 2x = 90°

2x = 90 - 22

2x = 68

x = 68 / 2

x = 34°

Furthermore:

If you have to find the value of 2x it would be 68, since

2x = 2(34) = 68°

A, E and B lie on a straight line segment. C, D and B lie on a straight line segment. BD = 3m, CD = 12m and AB = 19m. Work out the length of BE. Give your answer as a decimal. please help

Answers

Answer:

3.8m

Step-by-step explanation:

If A, E and B lie on a straight line segment. C, D and B lie on a straight line segment, based on their similarities,

AB/CB = BE/BD

Given

BD = 3m,

CD = 12m

AB = 19m.

CB = CD+BD

CB = 12+3 = 15m

On substituting

19/15 = BE/3

Cross multiply

15BE = 19×3

15BE = 57

BE = 57/15

BE = 3.8m

Hence the length of BE is 3.8m

Y=3x-2 y-2=x what is the soultions between the two equations

Answers

Answer:

(2, 4)

Step-by-step explanation:

"What is the solution of this system of equations?"

Substitute 3x - 2 for y in the second equation, obtaining:

3x - 2 - 2 = x

Consolidate like terms:  subtract x from both sides and add 4 to both sides:

2x = 4.  Thus, x = 2.  Substituting 2 for x in the first equation, we get:

y = 3(2) -2 = 4.

Thus, the solution is (2, 4)
