Christine bought 5 pink and yellow tulips to make a bouquet. The pink tulips cost $1 apiece and the yellow tulips cost $2 apiece. If Christine spent exactly $9 on the tulips, how many of each color did she buy?

The answer to your question is 1 pink and 4 yellow tulips

Step-by-step explanation:

Data

number of pink tulips and yellow = 5

cost of tulip yellow = y = $2

cost of tulip pink = p = $1

total cost = $9

Process

1.- Write equations to solve this problem

                 p + y = 5

               1p + 2y = 9

Solve by elimination

           -1 ( p + y = 5)                    - p  - y = -5

               1p + 2y = 9                     p  + 2y = 9

                                                      0   + y = 4

2.- Find p

              p + 4 = 5

              p = 5 - 4

              p = 1

3.- Conclusion

She bought 1 pink tulip and 4 yellow tulips                          

she bought 1 pink tulip and 4 yellow tulips.

Step-by-step explanation:

Let x represent the number of pink tulips that she bought.

Let y represent the number of yellow tulips that she bought.

Christine bought 5 pink and yellow tulips to make a bouquet. This means that

x + y = 5

The pink tulips cost $1 a piece and the yellow tulips cost $2 a piece. If Christine spent exactly $9 on the tulips, it means that

x + 2y = 9 - - - - - - - - - - -1

Substituting x = 5 - y into equation 1, it becomes

5 - y + 2y = 9

- y + 2y = 9 - 5

y = 4

x = 5 - y = 5 - 4

x = 1

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
