How do you solve for y in the equation 2y + 5x = 6?

• Add 2y to both sides and multiply by 5

• Subtract 2y from both sides and divide by 5

• Add 5x to both sides and multiply by 2

• Subtract 5x from both sides and divide by 2

Answer explanation

To solve for y in the equation 2y + 5x = 6, we need to isolate y. The correct choice is to subtract 5x from both sides and divide by 2, which gives us the value of y.

What is the Simple Interest Formula?

• I = P * r * t

• I = P + r + t

• I = P - r - t

• I = P / r / t

Answer explanation

The Simple Interest Formula is I = P * r * t. This formula calculates the interest (I) based on the principal amount (P), the interest rate (r), and the time period (t).

How do you solve for t in the Simple Interest Formula I = P * r * t?

• Divide both sides by I

• Multiply both sides by P * r

• Divide both sides by P * r

• Multiply both sides by I

Answer explanation

To solve for t in the Simple Interest Formula, divide both sides by P * r. This isolates t and gives the correct answer.
