6.A = 23 × 3 × 5 B = 22 × 3 × 52
frez [133]

Given:

The two numbers are

A=23\times 3\times 5

B=22\times 3\times 52

To find:

The highest common factor (HCF) of A and B

Solution:

We have,

A=23\times 3\times 5               ...(i)

B=22\times 3\times 52

All the factors of A are prime but the factors of B are not prime. So, it can be written as

B=2\times 11\times 3\times 13\times 2\times 2          ...(ii)

From (i) and (ii), it is clear that 3 is the only common factor of A and B. So,

HCF(A,B) = 3

Therefore, the highest common factor (HCF) of A and B is 3.

In a certain dart game, points are awarded for hitting a certain sections of the board. You get 5 points for each hit and lose 3
Jlenok [28]
So we have
h=hits
m=miss
h+m=10

gain 5 for every hit and lose 3 for every miss
so 5 times number of hit=points from hit
-3 times number of miss=points deducted from miss
add
5h-3m=18
so we have the equations

h+m=10
5h-3m=18

multiply first equation by 3
3h+3m=30
add to first equatio

3h+3m=30
<u>5h-3m=18  +</u>
8h+0m=48


8h=48
divide by 8
h=6
subsitute
h+m=10
6+m=10
subtract 6
m=4


6 hits
4 miss
