All you have to do is isolate m. We have to move all terms except m to the other side.

15 + 5m = 415

We have to cancel out the numbers. 15 is being added so we subtract it from both sides.

15 - 15 + 5m = 415 - 15

5m = 400

5 is being multiplied so we divide it on both sides.

5m/5 = 400/5
m = 80

We can plug in to prove.

15 + 5(80) = 415

15 + 400 = 415

415 = 415

Find<br> the<br> Inverse<br> y = x+10/7
Alona [7]

Answer:

x - \frac{10}{7}

Step-by-step explanation:

y = x + 10/7

x = y + 10/7

x = y + 10/7

x - 10/7 = y

y = x - 10/7

x - \frac{10}{7}

Simplify.
Alexus [3.1K]

Answer:

1/8

Step-by-step explanation:

To simplify the expression √3/√8, we can first simplify the square root terms by finding the prime factorization of each number under the square root. The prime factorization of 3 is 3, and the prime factorization of 8 is 2 * 2 * 2.

We can then rewrite the square root terms as follows:

√3/√8 = √(3) / √(2 * 2 * 2)

Next, we can use the property of square roots that says that the square root of a number is equal to the square root of each of its prime factors. This means that we can rewrite the square root term as follows:

√(3) / √(2 * 2 * 2) = √(3) / √(2) / √(2) / √(2)

Since the square root of a number is the same as the number itself, we can simplify the expression further by removing the square root symbols from the prime numbers 2:

√(3) / √(2) / √(2) / √(2) = √(3) / 2 / 2 / 2

Finally, we can use the rules of division to simplify the expression even further:

√(3) / 2 / 2 / 2 = √(3) / (2 * 2 * 2)

Since any number divided by itself is equal to 1, we can simplify the expression one last time to get our final answer:

√(3) / (2 * 2 * 2) = 1/2 * 1/2 * 1/2 = 1/8

Therefore, the simplified form of the expression √3/√8 is 1/8.
