Given that R = 6x + 9y

Mathematics
1 answer:
Grace [21]3 years ago
4 0

Answer:

11/3

Step-by-step explanation:

x=1, R=39, y=?

R=6x + 9y

(substitute the parameters into the equation)

39=6(1) + 9y

39= 6 + 9y

(collect like terms)

39 - 6 =9y

33=9y

(divide both sides by 9)

33/9=9y/9

11/3=y

therefore, y= 11/3

anyanavicka [17]

<u>The overall </u><u>algebraic  expression</u><u> will be:   </u>\frac{5(x+11)}{3(x+8)}<u />

Definition of algebraic expression -

An expression obtained by a finite number of the fundamental operations of algebra upon symbols representing numbers.

Five times the sum of a number and eleven, divided by three times the sum of the number and eight.

Let the number be x.

Five times the sum of a number and eleven means 5 multiplied to the sum of x and 11. In expression this will be written as:

5(x + 11)

Three times the sum of the number and eight means 3 multiplied to the sum of x and 8. In expression this will be written as:

3(x + 8)

So, the overall <u>algebraic</u> expression will be:    \frac{5(x+11)}{3(x+8)}
