The Vanderbloom family already traveled 200 miles on their vacation. The total distance that they will travel (d) is a function of their rate of travel (r) and their upcoming travel time (t). This is represented with the equation given below.

Answers

Answer:  t=r/d-200

Step-by-step explanation:

d-200=r/t+200-200

t*(d-200)=r/t*t

t(d-200)/(d-200)=r/d-200

t=r/d-200

A gift basket has 2 soaps and 5 lotions and costs $20. A second basket has 6 spas and 15 lotions and cost $60. Is it possible to determine the price of the soap?

Answers

A second basket has 6 spas--- I think you mean 6 soaps , so i will work with that

Answer:it is not possible to determine the price of the soap with the information given.

Step-by-step explanation:

Let s0ap be represented as x

and lotion be represented as y

2 soaps and 5 lotions costing  $20 gives us equation 1 as

2 x+ 5y= 20-------- equation 1

second basket with 6 soaps and 15 lotions and costing $60 gives us equation 2 as

6x + 15y= 60------equation 2

Step 2 -- Solving

2 x+ 5y= 20-------- equation 1

6x + 15y= 60--------equation 2

BY elimination method, we  multiply equation 1 by (3)

2x + 5y= 20  x (3)

6x + 15y=60-------equation 3

Subtraction of equation 3 from equation 2 gives us

6x + 15y=60-------equation 3

-6x + 15y= 60--------equation 2

0x +0y=0  which is no solution

Therefore it is not possible to determine the price of the soap

Solve the equation for x:
-3(x + 4) + 5x = 24

Answers

Answer:

[tex]-3(x + 4) + 5x = 24\\\\-3x - 12 + 5x = 24\\\\2x - 12 = 24\\\\2x = 36\\\\x = 18[/tex]

The solution for x in this equation is 18.

Answer:

x = 18

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

-3(x + 4) + 5x = 24

Step 2: Solve for x

Distribute -3:                    -3x - 12 + 5x = 24Combine like terms:        2x - 12 = 24Isolate x term:                  2x = 36Isolate x:                           x = 18

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                     -3(18 + 4) + 5(18) = 24Add:                                      -3(22) + 5(18) = 24Multiply:                                -66 + 90 = 24Add:                                      24 = 24

Here we see that 24 does indeed equal 24.

∴ x = 18 is the solution to the equation.

Answers

Answer:

x = x + 7

Step-by-step explanation:

In this equation, it is saying that x is equal to itself plus something else (7). This equation does not make sense at all because x cannot equal to something that is bigger or smaller than itself. If 7 is added to x, like the right-hand side of the equation, it cannot be equal to x from the left-hand side of the equation, so there is no solution to the value of x in this equation.

Answers

Answer:

           The first:    y = -25x + 180

Step-by-step explanation:

In every equation b = 170, so

The equation is  y =mx + 170

On the line on the graph, for x=2 we have y = 120,so:

 120 = m×2 + 170

 -50 = 2m

   m = 25

Therefore the equation is:

                                          y = -25x + 180

Given that :

Earning from Food booth cost :

Number of booth * cost

15(200 + 8d)

3000 + 120d

Earning from Game booth :

Number of booths * cost

20(65 + 7d)

1300 + 140d

Total sum :

Total earning from game booth and food booth

Answers

Answer:A, D, E

Step-by-step explanation:

ΔJKL and ΔJKM are similar triangles and ΔJKL and ΔKML are similar triangles. Therefore, options A and B are the correct answers.

What are similar triangles?

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

From the given figure, ΔJKL, ΔJKM and ΔKML are right angle triangles.

Now, consider ΔJKL and ΔJKM

∠JMK=∠JKL (Measure of angle is equal to 90°)

∠KJM=∠KJL (Reflexive property)

ΔJKL and ΔJKM are similar triangles

Consider ΔJKL and ΔKML

∠KML=∠JKL (Measure of angle is equal to 90°)

∠JLK=∠MLK (Reflexive property)

ΔJKL and ΔKML are similar triangles
