Example Question #21 : One Step Equations With Decimals
Solve for .
Divide both sides by . can also be expressed as . Both decimals each have one decimal place so the expression becomes: .
Example Question #22 : One Step Equations With Decimals
Solve for .
Divide both sides by . The denominator has less decimal places than the numerator so we just shift one decimal place for top and bottom: .
Example Question #321 : Algebraic Equations
Solve for
Multiply both sides by . When multiplying decimals, first multiply normally and then count the number of decimal places in the problem. We have . So starting from the right, we shift two places to the left to get a decimal of .
Example Question #322 : Algebraic Equations
Solve for .
Multiply both sides by . When multiplying decimals, first multiply normally and then count the number of decimal places in the problem. We have . So starting from the right, we shift one places to the left to get a decimal of .
Example Question #323 : Algebraic Equations
Solve for .
Multiply both sides by . When multiplying decimals, first multiply normally and then count the number of decimal places in the problem. We have . So starting from the right, we shift one place to the left to get a decimal of . Since we are multiplying with negative numbers, we need to determine if the answer is negative. There is one negative number and that means the answer is negative.
Example Question #324 : Algebraic Equations
Solve for .
Multiply both sides by . When multiplying decimals, first multiply normally and then count the number of decimal places in the problem. We have . So starting from the right, we shift one place to the left to get a decimal of .
Example Question #325 : Algebraic Equations
Solve for .
Multiply both sides by . When multiplying decimals, first multiply normally and then count the number of decimal places in the problem. We have . So starting from the right, we shift two places to the left to get a decimal of . Since we are multiplying with negative numbers, we need to determine if the answer is negative. There are two negative numbers and that means the answer is positive.
Example Question #21 : One Step Equations With Decimals
Solve for
Subtract both sides by .
Example Question #327 : Algebraic Equations
Solve for .
Subtract both sides by .
Next, we divide both sides by . The left side will have two negatives cancel out to be a positive .
Example Question #22 : One Step Equations With Decimals
Solve for .
Add both sides by .
