Answer:
or
Step-by-step explanation:
First we will convert the first term into an improper fraction. We multiply the whole number into the denominator and add the product to the numerator.
Then we will multiply the first term by 4/4 to match the denominator of the second term..
*
=
Finally we subtract.
=
From the given table we can see that mixture of 2 cups of blue paint and 10 cups of yellow paint produced green cups.
So , the ratio of yellow to blue is , .
We need to find , the number of cups of yellow paint should we mix with 1 cup of blue paint to make the same shade of green.
We know , produce same shade ratio should be constant.
Let , cups of yellow shade is x .
Therefore , cups of yellow shades required are 5.
Hence, this is the required solution.
Given that 2 large puzzle costs $16 then
2l=16
or
l=8
That means cost of 1 large puzzle = $8
Given that 3 small puzzle costs $15 then
3s=15
or
s=5
That means cost of 1 small puzzle = $5
Now we will use this information to find the correct choice.
---
First choice is <u>wrong </u>as coefficient 8 is with 8l so that gives cost of 1 large not small puzzle.
---
Second choice is <u>correct </u>as coefficient 8 is with 8l so that gives cost of 1 large puzzle.
---
Third choice is <u>correct </u>as coefficient 5 is with 5s so that gives cost of 1 small puzzle.
---
Fourth choice is <u>Wrong </u>as coefficient 5 is with 5s so that gives cost of 1 small not large puzzle.
---
Fifth choice is <u>wrong </u>as constant 128 gives total cost of not the total number of puzzles.
