Step-by-step explanation:
Answer:
30 pounds of raspberries and 50 pounds of blueberries
Step-by-step explanation:
Let's use b to represent blueberries and r for raspberries. Each pound of raspberries costs $1, so to find the total cost of raspberries we use 1r, which is just r. For blueberries, we do 3.25b.
r+3.25b=192.5
We also know that we can combine the numbers for 80 total pounds.
r+b=80
We can subtract the two equations we have made to eliminate the r and solve for b.
2.25b=112.5
We divide both sides by 2.25.
b=50
We know that r+b=80, so if b is 50 then r must be 30.
Have a wonderful day! :D
1. y^2 - 3y - 5 - (-y^2 - 7y + 4) = y^2 - 3y - 5 + y^2 + 7y - 4 =
2y^2 + 4y - 9 <===
2. 6xy^3z * 3x^2yx^2 = 18x^5y^4z
3. -3x^3(-2x^2 + 4x - 3) = 6x^5 - 12x^4 + 9x^3
4. (6p + 2)^2 = (6p + 2)(6p + 2) = 36p^2 + 12p + 12p + 4 =
36p^2 + 24p + 4.....coefficient is 24
5. (x - 5)(x^2 - 2x - 6) = x(x^2 - 2x - 6) - 5(x^2 - 2x - 6) =
x^3 - 2x^2 - 6x - 5x^2 + 10x + 30 =
x^3 - 7x^2 + 4x + 30 <===
