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

2 answers:

7 0

First you substitute the values. So 7(3) - 15/(5). 7 x 3 is equal to 21, so the equation is now 21 - 15/(5), and 15/5 is equal to 3. You are now left with 21- 3, which is equal to 18.

Find m and n

Considering the given angle, we have:

$\sin(60) = \frac{Opposite}{Hypotenuse}$

This gives:

$\sin(60) = \frac{m}{20}$

Make m ths subject

$m = 20 * \sin(60)$

$\sin(60) =\frac{\sqrt 3}{2}$

So, we have:

$m = 20 *\frac{\sqrt 3}{2}$

$m = 10\sqrt 3$

Considering the given angle again, we have:

$\cos(60) = \frac{Adjacent}{Hypotenuse}$

This gives:

$\cos(60) = \frac{n}{20}$

Make n the subject

$n = 20 * \cos(60)$

$\sin(60) =\frac{1}{2}$

So, we have:

$n = 20 *\frac{1}{2}$

$n = 10$

What is 45=m(25)+b solving for m

STatiana [176]

Answer:

$\frac{45-b}{25}$

Step-by-step explanation:

given

45 = 25m + b ( isolate the term in m by subtracting b from both sides )

45 - b = 25m ← divide both sides by 25

$\frac{45-b}{25}$ = m
