Which method will NOT solve this equation completely? -8 + 3y = 19 Add 8 to both sides, then divide both sides by 3. Divide both sides by 3, then add 8/3 to both sides. Add 8 to both sides, then multiply both sides by 1/3. Subtract 8 from both sides, then divide both sides by 1/3.

What is wrong with this solution? -6t + 16 = -8 Step One: -6t + 16 - 16 = -8 - 16 Step Two: -6 * -6t = -24 * -6 Solution: t = 144 -8 - 16 does not equal -24. -6t + 16 - 16 does not equal -6t. -6 * -6t does not equal t. Subtracting 16 from both sides does not undo the addition of 16.
You are solving 5 - 8/3 = y/3. Which equation will you get if you multiply both sides by 3? 3(5 - 8/3) = y/3 15 - 8 = y 5 - 8 = y 15 - 8 = y/9
Which step brings you closest to getting the variable alone on one side of the equation 16 = 7x - 5? Add 5 to both sides. Multiply both sides by 7. Subtract 5 from both sides. Divide both sides by 5.
The formula for the lateral surface area of a prism is S = Ph, where P represents the perimeter of the base and h represents the height of the prism.
The formula for the total surface area of a prism is S =Ph + 2B, where B, is for the area of the base, P is for the perimeter of the base, and h is for the height of the prism.
