For this case we have the following expression:
To verify the answer we have:
Multiplying both sides of the equation by -14:
Thus, the answer can be verified with:
Answer:
8×30=10×z
10z=240
z=24
Hence the value of z is 24
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:
x = 24, if thats wat ur asking.
