P 3 − 2 = 1 what is p?

Juli2301 [7.4K]

Answer: p = 1

Based on the assumption below.

Step-by-step explanation:

Is this 3p - 2 = 1? I don't quite understand the arrangement of the elements of the equation. I'll assume that since there is no operation sign for the "3," that it implies multiplication.

3p - 2 = 1

3p = 3

p = 1

Hey there!

First solving the equation 2^3 . . .

To solve 2^3, multiply the number 2 three times:

2 x 2 x 2 = 8

To find area, multiply the two sides . . .

(Since a square has all sides the same length, multiply 8 x 8)

8 x 8 = 64 <-------

The area of the shape is 64 inches.

Hope this helps you.
Have a great day!

In what different ways can 45 be written as the product of two positive integers?

nevsk [136]

First you need to know its common factors.

They are: 1, 3, 5, 9, 15, 45

And 45 = 1*45 = 3*15 = 5*9

So there should be 3 ways in total

roll the die twice. what is the probability of rolling a 6 on the 1st roll? an odd number on the 2nd roll?

Crank

The probability of rolling a 6 on the 1st roll is $\frac{1}{6}$ , since there is only 1 out of 6 sides of the dice that has six pips.

The probability of rolling an odd number is $\frac{1}{2}$ , since there are 3 out of 6 sides of the dice that has an odd number of pips. $\frac{3}{6} = \frac{1}{2}$

Then the probablity of both events happening one after another is $\frac{1}{12}$ . You have to multiply both probabilities of the events: $\frac{1}{6} * \frac{1}{2} = \frac{1}{12}$
