Answer:

(2,3)

Step-by-step explanation:

The given system is

y=3x-3

y=2x-1

We equate both equations and solve for x.

3x - 3 = 2x - 1

Group like terms to get:

3x - 2x =  - 1 + 3

x = 2

We put x=2 into y=3x-3 to get:

y = 3 \times 2 - 3 = 6 - 3  = 3

As an ordered pair the solution is (2,3)

The community college fine arts department sold three kinds of tickets to its latest dance presentation. The adult tickets sold
lana [24]

Answer:adult=75

Students = 200

Children=75

Step-by-step explanation:

Let x= adult tickets, y=students, z=child

x+y+z =350

Since x=z

y+2z= 350 -----------1

20x +12y + 10z = 4650

Since y=z

12y +30z = 4650 --------2

Using elimination method to solve eqn 1&2

Multiply eqn 1 by 12

12y + 24z = 4200

12y +30z = 4650

Subtract equ 2 from 1

-6z =-450

z=75, x = 75

y=350 -(75+75)

y= 200 tickets

Jose worked 2.5 hours more than William. together they worked a total of 22 hours. William worked h hours
nataly862011 [7]

I believe that the answer you're looking for is B. h+(h+2.5)=22.

h+(h+2.5)=22

h+h+2.5=22

Combine like terms.

2h+2.5=22

Subtract 2.5 from both sides.

2h=19.5

Divide both sides by 2.

h=9.75

Now let's check the work by plugging 9.75 into the equation.

9.75+(9.75+2.5)=22

9.75+9.75+2.5=22

22=22

So we now see that the answer choice <u>B.</u> Is correct! And William worked 9.75 hours. I hope that you found this helpful!

In ΔJKL, the measure of ∠L=90°, KL = 22 feet, and JK = 54 feet. Find the measure of ∠J to the nearest degree.
nydimaria [60]

We have been given that in ΔJKL, the measure of ∠L=90°, KL = 22 feet, and JK = 54 feet. We are asked to find the measure of angle J to nearest degree.

First of all, we will draw a triangle as shown in the attachment.

We can see from our attachment that side KL is opposite side to angle J and side JK is hypotenuse of right triangle.

We know that sine relates opposite side of right triangle to hypotenuse.

\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}

\text{sin}(\angle J)=\frac{22}{54}

Using inverse sine or arcsin, we will get:

\angle J=\text{sin}^{-1}(\frac{22}{54})

\angle J=24.042075905756^{\circ}

Upon rounding to nearest degree, we will get:

\angle J\approx 24^{\circ}

Therefore, the measure of angle J is approximately 24 degrees.
