What is the solution to the equation square root 5x-7= square root 3x+5

Answer:

Step-by-step explanation:

Just as a hint. On this editor, you have to use brackets a lot. We cannot be certain what you mean. I'm going to interpret the question one way, but there are others.

√(5x - 7) = √(3x + 5)

Square both sides.

(√(5x - 7) )^2 = (√(3x + 5) )^2

5x - 7 = 3x  + 5            

Add 7 to both sides.

5x - 7 + 7 = 3x + 5 + 7

Combine

5x = 3x + 12

Subtract 3x from both sides.

5x - 3x = 3x -3x + 12

Combine

2x = 12

Divide by 2

2x/2 = 12/2

x = 6

What is the solution of this system of linear equations?<br><br> 3y = x + 6<br><br> y – x = 3
Naya [18.7K]
<span>3y = x + 6
y – x = 3 ----------->  x=y - 3 (substitute in 1st equation)

3y = y - 3 +6
3y - y = 3
2y = 3
y = 2/3

x= y - 3 = 2/3 -3 = 2/3 - 9/3 =  - 7/3

</span>x= - 7/3, y = 2/3<span>

LiRa [457]

Answer:

There is not enough evidence to reject the null hypothesis.

Their sum is greater than the probability value ,  the data does not fit the experiment and the null is  accepted.

Step-by-step explanation:

There are 3 colors so degrees of freedom = 3-1 = 2

The chi square value = 0.85

The p value for chi square =0.85 for 2 degrees of freedom for the left tailed test to be 0.34623 for 0.1,0.05 and 0.01 significance level.

There is not enough evidence to reject the null hypothesis.

The  p value for chi square =0.85 for 2 degrees of freedom for the right tailed test to be 0.65377 for 0.1,0.05 and 0.01 significance level.

There is not enough evidence to reject the null hypothesis.

Their sum is greater than the probability value ,  the data does not fit the experiment and the null is  accepted.

Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles. A = 55°, a = 12, b = 14
Mkey [24]
The way you'd set it up would be sin55º/12=sinB/14 (you could also flip the equation so that 12/sin55º=14/sinB, you'll get the same answer either way). Multiply out so that its 14•sin55º=12•sinB, or 11.47=12•sinB. Divide both sides by 12 so that it looks like .96=sinB, then take arcsine of both sides (arcsin= x=sin^-1 theta+360n or x=180- (sin^-1 theta)+360n), which should give you about 72.88º and 107.12º.
