An expression is a finite combination of symbols that is well-formed according to rules that depend on the context. meaning it has no = sigh
To find the domain, you first need to find what x values will result in an imaginary number. To find this, solve the inequality -13-x >(or equal to)0. This comes out to x<(or equal to) -13. This means that’s the domain is [-13, negative infinity).
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
2000 is 10 as much as 200 is 1
