Part A: 0.10x + 0.25 = 0.80 (dimes are 10 cents or 0.10 dollars, quarters are 0.25 dollars)
Part B: Plug in what you DO know and solve the one you DON’T:
0.10x + 0.25(2) = 0.80
0.10x + 0.50 = 0.80. Subtract 0.50 from both sides:
0.10x = 0.30 (Divide both sides by 0.10)
x = 3
Therefore you have 3 dimes

Answer:
3 cookies/bag
Step-by-step explanation:
First of all, let's define a unit rate. A unit rate is a ratio of the amount of one measurement to one unit of another measurement term. Unit rates can be expressed as fractions.
Now, here is something easier for you to remember: <u>the second unit always have to be something with the quantity of 1</u>.
In this case, "3 cookies/bag" shows how there are three cookies per, or in each bag--which means 1 bag. The second unit, which is bag, has the quantity of one.
Answer:
Jonas = 60 pounds
Jane = 70 pounds
Remember- 5 or more, raise the score. 4 or less, let it rest.
Jonas is 63 pounds. 3 is less than 4, so rounded to the nearest ten would be 60 pounds.
Meanwhile, Jane is 67 pounds. 7 is more than 5, so we will raise the score.
So, 67 rounded to the nearest ten would be 70.
You have your answers. 60 and 70. Hope this helps!
