It's not commutative:
<em>a</em> * <em>b</em> = 3<em>a</em> + 2<em>b</em>
but
<em>b</em> * <em>a</em> = 3<em>b</em> + 2<em>a</em>
We have equality only for
3<em>a</em> + 2<em>b</em> = 3<em>b</em> + 2<em>a</em> → <em>a</em> = <em>b</em>
Answer:
The total number of boys = 105
Step-by-step explanation:
The ratio of boys to girls = 3: 4
⇒ For every 3 boys, there are 4 girls.
Now, total number of students = 245
Let the common ratio of boys to girls is k.
So, 3k + 4k = 245
or , 7k = 245
⇒ k = 245/7 = 35
⇒ k = 35
Hence, the number of boys = 3k = 3 x 35 = 105
and number of girls = 4k = 4 x 35 = 140
Answer:
y = 12x + 600
Step-by-step explanation:
Prime factors are multiplying numbers that cannot be divided into smaller numbers.
Let's break down 92.
Divide 92 by 2.
2 x 46.
We can still break this down.
Divide 46 by 2.
2 x 2 x 23.
This is your prime factorization of 92.
I hope this helps!
