Evaluate 7r-(15 )/(s) when r=3 and s=5.

Given Expression and Values: We are given the expression 7r - (15/s) and the values r = 3 and s = 5. We need to substitute these values into the expression and simplify.Substitute r = 3: First, substitute r = 3 into the expression. This gives us 7 * 3 - (15/s). Calculation: 7 * 3 = 21Substitute s = 5: Next, substitute s = 5 into the expression. This gives us 21 - (15/5). Calculation: 15/5 = 3Calculate Result: Now, subtract the result of 15/5 from 21. This gives us 21 - 3. Calculation: 21 - 3 = 18Final Value: The final value of the expression 7r - (15/s) when r = 3 and s = 5 is 18.

Q. Evaluate

\newline

7r - \frac{15}{s}

when

\newline

r=3

and

\newline

s=5.

Given Expression and Values: We are given the expression $7r - \frac{15}{s}$ and the values $r = 3$ and $s = 5$ . We need to substitute these values into the expression and simplify.
Substitute $r = 3$ : First, substitute $r = 3$ into the expression. This gives us $7 \times 3 - (15/s)$ . $\newline$ Calculation: $7 \times 3 = 21$
Substitute $s = 5$ : Next, substitute $s = 5$ into the expression. This gives us $21 - (15/5)$ . $\newline$ Calculation: $\frac{15}{5} = 3$
Calculate Result: Now, subtract the result of $\frac{15}{5}$ from $21$ . This gives us $21 - 3$ . $\newline$ Calculation: $21 - 3 = 18$
Final Value: The final value of the expression $7r - \frac{15}{s}$ when $r = 3$ and $s = 5$ is $18$ .
