Answer:
Step-by-step explanation:
We wil define:
1) "x" as number of cans inside the truck.
2) "y" as number of bottles inside the truck.
We now that the amount of both cans and bottles inside the truck is "980". This quantity is equal to the sum of cans and bottles, so now we can write:
We will call this expression equation n° 1.
On the other hand, we know that the total weight is a sum of the weight of the cans and the weight of the bottles. The total weight of the cans, for example, is the result of multiplying the numbers of cans in the truck with the weight of each can, like here: (
So now we can write:
We well call this expression equation n° 2.
From equation n°1 we obtain "y", like this:
And we replace it in equation n°2:
Now we have the expression of the total weight considering the amount of cans in the truck.
*** IMPORTANT: there is a character similar to an "A" that i can't erase, maybe is a mistake from brainly. Do not consider it as part of the solution.
4.05 with (05) repeating if converted to a fraction or mixed number will be
.
As per the question statement, we are provided with a repeating decimal, 4.05 with (05) repeating.
We are required to convert the repeating decimal into a mixed number.
To solve this question, we need to know the formula to convert any repeating decimal number to a fraction which goes as:
Where, DN denoted the concerned Decimal Number,
(F = 10) if one repeating is number, 100 if two repeating numbers, 1000 if three repeating numbers and so on.
NRP denotes the Non-repeating part of decimal number.
And, D = 9 if one repeating number, 99 if two repeating numbers, 999 if three repeating numbers, and so on, similar to F.
Then, using our given data in the above formula, we get
4.05 with (05) repeating = .
