Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x = 7,3
Answer:
120
Step-by-step explanation:
The sum of the angles is 180 since it forms a straight line
2x+ x+90 = 180
Combine like terms
3x +90=180
Subtract 90 from each side
3x+90-90=180-90
3x= 90
Divide each side by 3
3x/3 = 90/3
x = 30
We want angle DBC = x+90
= 30+90
=120
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: 4^3
Step-by-step explanation: A number (4 in this case) is raised to the number of times it is multiplied by itself. 4 is multiplied by itself 3 times so 3 is the exponent.
