Step-by-step explanation:

Step one:

sample space

A bag contains

5 cherry,

8 orange,

2 grape,

7 bubblegum, and

3 apple  lollipops.

sample size= 5+8+2+7+3= 25

Required:

The probability of choosing grape for your first lollipop

and orange for your second?

1. The probability of choosing the grapes lollipops

=2/25

2. the probability of choosing the orange  lollipops----Note in the second choice the sample size will reduce because the first choice was done with out a replacement

=8/24

The total is

2/25*8/25= 16/625

Slope of line 2*(slope of line 1 )= -1

Slope of line 2 *-6\5=-1

You and your friends want to take a vacation to florida. The 5 of you will split the cost of the trip evenly. Each person has said that they would chip in up to $600 for the trip. What amounts represent possible total costs of the trip?

Answers

Answer:

[tex]Total\ Cost = \$3000[/tex]

Step-by-step explanation:

Given

[tex]Individuals = 5[/tex]

[tex]Cost = \$600[/tex] --- per individual

Required

Determine the total costs

Since each individual brings the same amount.

The total cost is calculated as follows:

[tex]Total\ Cost = Cost * Individuals[/tex]

[tex]Total\ Cost = \$600 * 5[/tex]

[tex]Total\ Cost = \$3000[/tex]

Anna has more money than Betty. If Anna gave Betty $200, then they would have the same amount of money. While if Betty gave Anna $220, Anna would then have twice as much as Betty. Calculate the amount of money each girl has using the substitution method

Answers

Answer:

Anna has $1460

Betty has $1060                                                      

Step-by-step explanation:

let Anna's money be x

and Betty's money be y

If Anna gave Betty $200, then they would have the same amount of money

Anna's money will reduce by 200

x=x-200

Betty's money will increase by 200

y= y+200

if they have the same amount of money, the difference will be zero

x-200=y+200

x-200-y-200=0

x-y-400=0

x-y=400--------------1

this means that Anna has $400 more than Betty

if Betty gave Anna $220, Anna would then have twice as much as Betty.

Betty's money will reduce by 220

y=y-220

Anna's money will increase by 220

x=x+220

Anna's money will double that of Betty's

x+220=2(y-220)

x+220= 2y-440

x=2y-440-220

x=2y-660--------------------2

put x= 2y-660 in eqn 1

(2y-660)-y=400-------------------------1

2y-y=400+660

y= 1060

so Betty has $1060

put y= 1060 in eqn 1

x-y=400

x-1060=400

x=400+1060

x=1460

so Anna has $1460

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.

What is the GCF of 64, 160 and 224

The greatest common factor of 64,160, and 224 will be 32.

What is the greatest common factor?

The greatest common factor is the largest positive number which can be divided into given numbers evenly. The greatest common factor is the highest number which divides all the given numbers completely.

Given numbers 64, 160 and 224. The greatest common factor is calculated by factorizing the given numbers.

Factorize number 64.

64 = 2x2x2x2x2x2

Factorize the number 160.

160 = 2x2x2x2x2x5

Factorize the number 224.

224 = 2x2x2x2x2x7

The common number between all three numbers is 2² or 32. Therefore, the greatest common factor of 64,160, and 224 will be 32.
