Answer:

Adults $ 17

Students: $8

Step-by-step explanation:

Adults: x

Students: y

a) 25x + 31y = 673

b) 27x +31y = 707

Elimination:

a) -1(25x + 31y = 673) = -25 -31y = -673

a + b

= (-25 -31y = -673) + (27x + 31y = 707)

= 2x = 34

x = 34/2

x = 17

Substitution a or b:

a) 25(17) + 31y = 673

425 + 31y = 673

31y = 673 - 425

31y = 248

y = 248/31

y = 8

!. PLEASE HELP!!! will mark brainliest!!
NeX [460]

Matter exists in three states; <em>solid, liquid and gas.</em>

The statement that corrects the error in his table is:

<em>D. The Solids column and the gas column should be switched because solids have a definite shape and volume and gases have no definite shape or volume. </em>

<em />

<em />

Looking at the table, we have the following observations.

  • <em>The solid column shows indefinite shape (because the particles fill in the container)</em>
  • <em>The liquid column is properly cataloged</em>
  • <em>The gas column shows a definite shape</em>

<em />

Solid has definite shape, while gas doesn't.

To make corrections, Marcus needs to switch the gas and the solid column.

Lesechka [4]

Answer: 60= $3.00 and 30= $4.00

x=# of $3 tickets

90-x=# of $4 tickets

$3x+$4(90-x)=$300

3x+360-4x=300

-x+360=300

-x=-360+300

-x=-60

x=60 $3 tickets

90-60=30 $4 tickets
