A standard number cube has 6 sides, and so the numbers are:

1,2,3,4,5,6

P, is any of those numbers that are not 2.

2 is one of the numbers in 6, and so it is 1/6 of the die.

6/6 - 1/6 = 5/6

C) 5/6 is your chance of getting a number that is not 2

hope this helps

Its 5/6 since we are excluding the number two (6-5=1)

He sum of two consecutive integers is â71â71. find the two integers

Crank

The two consecutive integers can be represented by x and x+1.

x+(x+1)=71

Combine like terms
2x+1=71

Subtract 1 from both sides
2x=70

Divide both sides by 2
x=35

Final answer: 35, 36

Emily wants to buy a car. She pays a deposit equal to 20% of the cost of the car. She will pay the balance in 8 equal payments o

olga55 [171]

Answer: the cost of the car is $54600

Step-by-step explanation:

Let x represent the cost of the car.

She pays a deposit equal to 20% of the cost of the car. This means that the amount of money that she paid as deposit would be

20/100 × x = 0.2 × x = 0.2x

The remaining balance would be

x - 0.2x = 0.8x

She will pay the balance in 8 equal payments of $5460 each month. This means that

0.8x/8 = 5460

0.1x = 5460

Dividing the left hand side and the right hand side of the equation by 0.1, it becomes

0.1x/0.1 = 5460/0.1

x = 54600

Jose walks at a rate of 4 miles per hour and runs at a rate of 8 miles per hour. Each week, his exercise program requires him to

Nastasia [14]

Answer:

Here we can use the relationship:

Distance = time*speed.

When Jose walks, his speed is 4 mph.

Then if he walks for X hours, the distance that he will travel is:

D = 4mph*X

When Jose runs, his speed is 8mph.

Then if he runs for T hours, the distance that he will travel is:

D´ = 8mph*Y

And we know that he travels in total 20 miles, then we must have that:

D + D´= 20mi

This leads to:

4mph*X + 8mph*Y = 20mi

Where X is the time that he walked, and Y is the time that he runed.

Then the equation that represents the different amounts of times that Jose runs and walks is:

4mph*X + 8mph*Y = 20mi

Where we can not really find the solutions for Y and X, because there is only one equation and two variables.
