Answer:

30 and 6

Explanation:

Let the numbers be x and y. Then

<span>x+y=36</span>
<span>x−y=24</span>

Adding the two equations together gives

<span>2x=60</span>

<span>∴x=30</span>

Substituting this back into either of the equations gives <span>y=<span>6</span></span>

Sum means add.
difference means subtract.

x + y = 36
x - y = 24  Just to make it complete, I finish the problem. Add the two equations.
=======
2x = 60 Divide by 2
x = 60/2
x = 30


x + y = 36 Substitute for x
30 + y = 36 Subtract 30
y = 36 - 30
y = 6

So the solution point is (30,6)

At the city museum, child admission is $6.10 and adult admission is $9.30 . On Sunday, four times as many adult tickets as child
dalvyx [7]

Answer:

21 child tickets

Step-by-step explanation:

For this problem, you'd use a system of equations.

First, define your variables.

x = # of child tickets sold

y = # of adult tickets sold

There were 4 times as many adult tickets (y) as child tickets (x) sold, so:

4 x = y

4 x - y = 0

93 (4 x - y = 0)

372 x - 93 y = 0

The total revenue was $909.30, adult tickets were $9.30 each, child tickets were $6.10 each, so:

6.10 x + 9.30 y = 909.30

10 (6.10 x + 9.30 y = 909.30)

61 x + 93 y = 9093

372 x - 93 y = 0

433 x = 9093

433 x / 433 = 9093 / 433

x = 21

(trom Unit 4, Lesson 11)
Dima020 [189]

Answer:

The number of kids NOT wearing socks in the gym = 20

Step-by-step explanation:

Here, the total number of kids in the gym = 80

Now, 75% of the kids are wearing socks.

Let us assume the number of kids wearing socks  = m

⇒ 75 % of 80 = m

Calculating the value of m ,we get:

\frac{75}{100}  \times 80 = m\\\implies  m = 60

⇒ 60 kids are wearing socks.

Kids not wearing socks = Total kids in gym - Kids wearing socks

= 80 - 60 = 20

Hence, the number of kids NOT wearing socks in the gym = 60.
