So you have 20% of blue and 50% of black.
So you have 70% in total that are both blue and black.
100%- 70%= 30%
So that means 30% were neither blue or black.
Do a proportion
30/100= x/30
30 x 30= 900
900 divided by 100= 9
Answer is 9 shirts are neither blue or black

Answer:
- 2 1/4 pounds of blueberries
Step-by-step explanation:
Blueberries - b, raspberries - x
<u>Equations as per question:</u>
<u>Eliminate b and solve for x:</u>
- 1/5x = x - 1 4/5
- x - 1/5x = 1 4/5
- 4/5x = 9/5
- x = 9/5 : 4/5
- x = 9/5 *5/4
- x = 9/4
- x = 2 1/4
Answer:
C. 4 times x squared plus 6 times x minus 3 minus 12 over the quantity 2 times x plus 1
Step-by-step explanation:
f(x) = 8x^3 + 16x^2 − 15
g(x) = 2x + 1.
f(x) / g(x) = (8x^3 + 16x^2 − 15) / (2x + 1)
Using long division
Type 1 rice :
7-ounce package costs = 2.59.
Cost of 1-ounce of Type 1 rice= 2.59/7 = $0.37
Type 2 rice :
12-ounce package costs = $4.56
Cost of 1-ounce Type 2 rice = 4.56/12 = $0.38
Type 3 rice :
18-ounce package costs = $ 6.30
Cost of 1-ounce Type 3 rice = 6.30/18 = $0.35.
From the above calculations, we can see that the cost of 1-ounce Type 3 rice is lowest. Therefore, 18-ounce package is Best Buy.
