At an amusement park, Bill enjoys two rides on the water slide and three rides on the Ferris wheel, and it cost him $15.55. If the water slide costs $3.95, find the cost of the Ferris wheel.

Answers

Answer:

the answer is $2.55

Step-by-step explanation:

$3.95×2=$7.90

$15.55-7.90=7.65

$7.65÷3=$2.55

Answer:

If your looking for the amount of money it took for him on EACH indivisual ride on the Ferris wheel it is $2.55. If your looking for the TOTAL amount that he rode on the Ferris wheel all-together the answer is $7.65.

Step-by-step explanation:

$15.55 - $7.90(the amount he rode on the water slide twice) = $7.65.

Two lines, A and B, are represented by the equations given below:

Line A: y = x − 4
Line B: y = 3x + 4

Which of the following shows the solution to the system of equations and explains why?

(−3, −5), because the point satisfies one of the equations
(−3, −5), because the point lies between the two axes
(−4, −8), because the point satisfies both equations
(−4, −8), because the point does not lie on any axis

Answers

Answer:

(−4, −8), because the point satisfies both equations

Step-by-step explanation:

Line A

y = x - 4

Line B

y = 3x + 4

If we equate those 2 equations

x - 4 = 3x + 4

2x = -8

x = -4

y = -8

Answer:

C. (-4,-8), because the point satisfies both equations

Step-by-step explanation:

You need to graph both equations. For line A, the y-intercept is -4, so you plot a point on -4. The slope is one, so you rise up one and run right 1. For line B, the y-intercept is 4, so you plot a point on 4. The slope is 3, so you rise up 3 and run right 1. Then, you look for where the 2 lines intersect. In this case, line A and line B intersect at the point (-4,-8).

write an expression that is equivalent to 1/3x + 3/4 + 2/3x - 1/4 - 2/3x

PLEASE HELP. and be fr don't put something.... d....u....m....b

Answers

Answer: 1/3x + 1/2

Step-by-step explanation: combine like terms. 1/3x + 2/3x - 2/3x = 1/3x

3/4 - 1/4 = 1/2

Therefore, the answer is 1/3x + 1/2

This question is based on the simple calculation. Therefore, the expression is equivalent to

[tex]\dfrac{1}{3}x +\dfrac{3}{4} +\dfrac{2}{3} x - \dfrac{1}{4} - \dfrac{2}{3}x[/tex] is [tex]\dfrac{1}{3} x+\dfrac{1}{2}[/tex] .

Given:

[tex]\dfrac{1}{3} x+\dfrac{3}{4} +\dfrac{2}{3} x - \dfrac{1}{4} - \dfrac{2}{3}x[/tex]

We need to determined an expression that is equivalent to[tex]\dfrac{1}{3}x +\dfrac{3}{4} +\dfrac{2}{3} x - \dfrac{1}{4} - \dfrac{2}{3}x[/tex]

Now, solve it further as follows:

Separate the like terms , we get,

[tex]\dfrac{1}{3}x +\dfrac{2}{3} x-\dfrac{2}{3} x+\dfrac{3}{4} - \dfrac{1}{4}[/tex]

Thus, further calculated we get,

[tex]\Rightarrow \dfrac{1}{3} x+\dfrac{1}{2}[/tex]

Therefore, the expression is equivalent to

[tex]\dfrac{1}{3}x +\dfrac{3}{4} +\dfrac{2}{3} x - \dfrac{1}{4} - \dfrac{2}{3}x[/tex] is [tex]\dfrac{1}{3} x+\dfrac{1}{2}[/tex] .

In two or more complete sentences, describe how you would draw the graph of the solution set for the following inequality. 3m + 18 < 30
Take the time to actually solve this and explain it because I can't comprehend anything right now ._. and the last answers I got were not the best))

Answers

Answer:

1.5

Step-by-step explanation:

okay so what you are going to do first is put a line down where the < is this will separate 3m+18 and 30.

next you want to make the M by itself so you are going to subtract 3 from both sides so 3m-3 and 30-3.

30-3=27

okay now your problem should look like this 18<27

then you are going to divide the problem 27/18

once you divide 27/18 1.5 should be your answer or if you need it in a fraction form your answer will be 1 1/2
