The best answer for the question is C - The equation is not true for any value of x.
The reason for this is if we subtract 3x from both sides, there are no variables left. since there are no variables left, we know since first grade that 8 does not equal to -5....with that being true, there is no value we can assign to x to make this a true statement.
Answer:
45% round 55% rectangular
Answer:
3/4 or a 75% chance
Step-by-step explanation:
Out of 4 cards ( 2 3 4 5), here are the cards greater than 3: 4, and 5. That leaves you with a 2/4 chance of drawing one of them. (2 cards, 4 in total).
Then, picking a 4 out of 4 cards is a 1/4 chance; since that is one card out of 4 total possibilities.
1/4 + 2/4 = 3/4. Or, a 75% chance.
Answer:
![x\approx7.8](https://tex.z-dn.net/?f=x%5Capprox7.8)
Step-by-step explanation:
In relation to the given angle, we are given the triangle's opposite side and hypotenuse. Therefore, we use the sine function to set up a proportion and solve for the opposite side:
![sin(\theta)=\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=sin%28%5Ctheta%29%3D%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
![sin(23^\circ)=\frac{x}{20}](https://tex.z-dn.net/?f=sin%2823%5E%5Ccirc%29%3D%5Cfrac%7Bx%7D%7B20%7D)
![20sin(23^\circ)=x](https://tex.z-dn.net/?f=20sin%2823%5E%5Ccirc%29%3Dx)
![x=20sin(23^\circ)](https://tex.z-dn.net/?f=x%3D20sin%2823%5E%5Ccirc%29)
![x\approx7.8](https://tex.z-dn.net/?f=x%5Capprox7.8)
Therefore, the length of the opposite side is about 7.8 units
I think it’s B, or 0.10x+0.15(50-x)=0.12(50)
Because 10% would give you 30ml, and 15% would equal 20ml to get 50ml, according to the equation.
