3+(-5)x=19
Subtract 3 from both sides of the equation.
-5x= 16
Divide by -5 on both sides
X= -3.2
Answer:
5%
Step-by-step explanation:
Given that:
Theoretical probability = 50%
The experimental probability = number of desired outcome / number of trials
Hence, experimental probability = 45 / 100 = 0.45
0.45 = 0.45 * 100% = 45%
Percentage difference in theoretical and experimental probability :
Theoretical - experimental
50% - 45% = 5%
<u>Answer-</u>
<em>The values of </em><em>x and y are 20° and 30</em><em>, respectively.</em>
<u>Solution-</u>
As in the given triangle all the angles are same so it must a equilateral triangle.
In an equilateral triangle all the measurements of the angles and side length are same. The measurement of the angels are 60°.
As given in the question one side length is 46, so all the side length are same.
So,

We know that an exterior angle of a triangle is equal to the sum of the opposite interior angles. 80° is the exterior angle opposite to x and one angle of triangle at the top vertex.



Therefore, the values of x and y are 20° and 30, respectively.
Answer: 2
Step-by-step explanation:
2.5(6x-4)=10+4(1.5+0.5x) [Work out the brackets]
15x-10=0+6+2x [Solve]
15x-10=16+2x [Convey the terms]
15x-2x=16+10 [Add up the same terms and calculate]
13x=26 [Divide both parts]
x=2
