Since d is being subtracted from bc, we first add d to each side. Now we are left with a + d = bc.
Since b is being multiplied by c to be bc, we divide both sides by c.
We now have a/c + d = b
Your solution is: b = a/c + d

Explain how an estimate helps you place the decimal point when multiplying 3.9 × 5.3

Elza [17]

So you can round 3.9 to 4, and 5.3 to 5. so 4x5=20. there would then be 2 digits in front of the decimal point. (:

Jin needs 0.8 gram of carbon for an experiment. She needs 4.15 times as much water. Jins says that she needs less than 4.15 gram

natima [27]

Answer:

That is a correct statement.

Step-by-step explanation:

This is because to find the appropriate amount, we would multiply the two numbers together. Since we are multiplying 4.15 by a number less than 1 (0.8), the number can only be lower. The number would only be higher if the number was greater than 1.
