3p + 34 = 90
3p = 90 - 34
3p = 56
p = 56/3
p = 18.67 (thats rounded)
2r + 44 = 76
2r = 76 - 44
2r = 32
r = 32/2
r = 16
53 + 6s = 1421
6s = 1421 - 53
6s = 1368
s = 1368/6
s = 228
" the product " means multiply
p x r x s = 18.67 x 16 x 228 = 68,108.16
Total flour used = Sum of all the cups
Total = 2 cups + 0.5 cups + 1.75 cups
= 4.25 cups of flour
4.25 cups of flour was used.
Hope this explains it.
Answer:

Step-by-step explanation:
According to the given information,
- Pairs of black pants = 2
- Pair of brown pants = 1
- Pairs of blue pants = 2
Then, total pairs of pants = 2 + 1 + 2 = 5
Similarly,
- Pink T-shirts = 2
- Blue T-shirts = 2
Then, total number of T-shirts = 4
This gives us the total nunber of clothing articles with Jenny, i.e.,
Total pairs of pants + Total number of T-shirts
= 5 + 4
= 9
Now, the probability of pulling out a pair of black pants & a blue T-shirt will be:
Total pairs of black pants + Total nunber of blue T-shirts/Total clothing articles
= 2 + 2 / 9
= 4/9

Given:
The statement is "Five times the difference of the cube of y and the square of x".
To find:
The algebraic expression for the given statement.
Solution:
We know that,
Cube = Power 3
Square = Power 2
Difference = Minus (-)
Times = Multiplication (×)
Now,
Cube of y = 
Square of x = 
Difference of the cube of y and the square of x = 
Five times the difference of the cube of y and the square of x is:
Required expression = 
Therefore, the correct option is C. The required algebraic expression for the given statement is
.
