Both form straight angles, which are 180 degrees.

x+4y+x+y=180
2x+5y=180

4x+y=180

Solve the second equation for y and substitute the variable.
y= -4x+180

2x+5(-4x+180)=180
2x-20x+900=180
-18x= -720
x=40

Plug the x value in
4(40)+y= 180
160+y=180
y=20

Final answer: x=40, y=20

X+4y+x+y= 4x+y=180
simplify by adding like terms
2x+5y= 4x+y=180
Subtract y from each side
2x+4y=4x=180
Subtract 2x from each side
4y=2x=180
y=180/4=45
x=180/2=90

Answer: the final mass of the solid is 176 grams.

Step-by-step explanation:

The "change" between two quantities, one initial Qi and one final Qf is defined as:

Change = Qf - Qi.

In this case, the quantity is mass, and we know that the initial mass is 260 grams.

And we also know that the change is -84 grams.

Then we have the equation:

Qf - 260 g = -84g

Qf = -84g + 260g = 176g

So the final mass of the solid is 176 grams.

3. Tickets to a show cost $5.50 for adults and 54.25 for students. A family is purchasing2
bulgar [2K]

.

Step-by-step explanation:The cost of an adult ticket to the show is $5.5

The cost of a student ticket to the show is $4.25

A family is purchasing 2 adult tickets and 3 student tickets. This means that the total cost of 2 adult tickets would be

2 × 5.5 = $11

It also means that the total cost of 3 student tickets would be

3 × 4.25 = $12.75

The total cost of 2 adult tickets and 3 student tickets would be

11 + 12.75 = $23.75

If the family pays $25, the exact amount of change they should receive is

25 - 23.75 = $1.25
