$\bold{Answer}$

$\boxed{\bold{X \ = \ 27}}$

$\bold{Explanation}$

$\bold{Solve: \ \frac{2}{3}x-\frac{1}{9}x+5=20}$

$\bold{--------------------------}$

$\bold{Subtract \ 5 \ From \ Both \ Sides}$

$\bold{\frac{2}{3}x-\frac{1}{9}x+5-5=20-5}$

$\bold{Simplify}$

$\bold{\frac{2}{3}x-\frac{1}{9}x=15}$

$\bold{Multiply \ By \ LCM: \ LCM \ = \ 9}$

$\bold{\frac{2}{3}x\cdot \:9-\frac{1}{9}x\cdot \:9=15\cdot \:9}$

$\bold{Simplify}$

$\bold{6x-x=135}$

$\bold{5x=135}$

$\bold{Divide \ Both \ Sides \ By \ 5}$

$\bold{\frac{5x}{5}=\frac{135}{5}}$

$\bold{Simplify}$

$\bold{X \ = \ 27}$

$\boxed{\bold{Eclipsed}}$

The graph shows two lines, A and B.

EastWind [94]

Answer:

Part A: one solution:

Part B: x = 3, y = 4.

Explanation:

1) Part A: how many solutions does the pair of equations for lines A and B have?

The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.

In this case, there are two straight lines, which intersect in one and only one point.

Hence, the system has one solution.

2) Part B: what is the solution to the equations of lines A and B?

The solution is the pair of coordinates of the intersection point. It is (3, 4).

Therefore, the solution is x = 3, y = 4.

Using the information above regarding the proportion of agenda-less meetings, choose the correct conclusion for this hypothesis

ruslelena [56]

Answer: There is sufficient evidence to conclude that the proportion of agenda-less meetings is greater than 45%.

Step-by-step explanation:

Given: $H_0:p=0.45 \\ H_a:p>0.45$

The p-value for this hypothesis test is 0.025.

The level of significance is α=0.05

As p-value< α ∵0.025< 0.05

[if p-value< α , we reject $H_0$ ]

then, we reject the null hypothesis.

i.e. We have sufficient evidence to support the alternative hypothesis.

Hence, the correct statement is : There is sufficient evidence to conclude that the proportion of agenda-less meetings is greater than 45%.
