Question

39+480÷r=45 ПЛИИИИЗ ПАМАГИТЕЕЕ СРОЧНО​

Answer 1

39+480:r=45
480:r=45-39
480:r=6
r=480:6
r=80
39+480:80=45
45=45

Answer 2

Calculation Solution

To solve the equation 39 + 480 ÷ r = 45 for r, we can follow these steps:

1. Subtract 39 from both sides of the equation to isolate the term involving r. 2. Then, divide both sides by the coefficient of r to solve for r.

Let's solve it step by step:

1. Subtract 39 from both sides: - 480 ÷ r = 45 - 39 - 480 ÷ r = 6

2. Now, to solve for r, we can rewrite the equation as: - r = 480 ÷ 6 - r = 80

So, the value of r that satisfies the equation 39 + 480 ÷ r = 45 is 80.

This solution is based on the mathematical principles of solving equations and isolating variables.
