Total these measurements. your answer should indicate the proper accuracy. be sure to include the g in your answer.
(remember when adding figures, you need to round your answer so that it reflects the figure in the problem with the least amount of significant figures to the right of the decimal if a decimal is present).

6.8321 g

7.5248 g

Ok so to add decimals, we add them like normal numbers..

6.8321 g

+7.5248 g

3.4669

And since we are trying to round, we make it..

3.5, since the 4 rounds up to a 5 because of the 6.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
