To solve these equations, you should understand that multiplication simple means adding a number (the multiplicand) to itself a specified number of times. For example 3 x 2, means adding 3 to itself 2times "3+3 = 6" , another example 5 x 3, means adding 5 to itself 3times "5+5+5 = 15"

So,

43x7=301 ....add 43 to itself 7times

12x9=108

10x6=60

9x7=63

7x5=35

6x3=18

0x8=0

30x3=90

11x8=88

73x2=219

83x5=415

16x8=128

392x7=2,744

29x4=116

761x9=6,849

4,829x6=28,974

12x7=84

25,500x4=102,000

Answer:

Proper Subsets = 1023

Step-by-step explanation:

GivenW= \{Hampton\ Hotels, Anytime\ Fitness, Subway, Jack\ in\ the\ Box, Supercuts, \\Jimmy\ Johns, Servpro, Denny's, Pizza\ Hut, 7-Eleven\}

Required

Determine the proper subsets

Proper Subset (P) is calculated using;

P = 2^n - 1

Where

n = number\ of\ elements

In this case;

n = 10

So:

P = 2^n - 1

P = 2^{10} - 1

P = 1024 - 1

P = 1023

Hence;

<em>Proper Subsets = 1023</em>

Two numbers are between 10 and 20. Their greatest common factor is 3. Which two numbers could they be?
alina1380 [7]

Answer:

12 and 15     or

12 and 18    or

15 or 18

Step-by-step explanation:

The two numbers have to both be divisible by 3, since their greatest common factor is 3.  This only leaves..

12, 15, or 18     (no other numbers between 10 and 20 are divisible by 3)

The factors of 12 are: 2, 3, 4, 6, and 12

The factors of 15 are: 3, 5, and 15

The factors of 18 are: 2, 3, 6, 9, and 18

All three numbers have 3 as a greatest common factor, so we have 3 pairs of numbers they could be...

12 and 15     or

12 and 18    or

15 or 18
