Beth, James and Buzz put their money together for a gift for their father on Father's Day. The gift cost them $75 all together.

Phoenix [80]

Hello!

We are told that the Father’s Day gift was $75, the cost of which was split between three people. This can be represented using the following equation:

(Beth) + (James) + (Buzz) = $75

We know that Beth and James each contributed $25. Now we can rewrite the equation with the given information and then simplify:

$25 + $25 + (Buzz) = $75

$50 + (Buzz) = $75

Now subtract $50 from both sides and simplify:

$50 (-$50) + (Buzz) = $75 (-$50)

Buzz = $25

We have now proved that Buzz contributed $25.

I hope this helps!

Mrs. Smith took her family and friends to the movies. There was a total of 15 people. Child tickets cost 5$ and adult tickets co

SCORPION-xisa [38]

Answer: children= 8, adult= 7

Step-by-step explanation:

Let the number of children be x

Let the number of adults be y

There was a total of 15 people. This can be represented as:

x + y = 15 .......... equation i

Child tickets cost 5$ and adult tickets cost 10$. She then spent a total of 110$. This can be represented as:

5x + 10y = 110 ............. equation ii

Combine both equations

x + y = 15 ........... equation i

5x + 10y = 110 .......... equation ii

Multiply equation I by 5

Multiply equation ii by 1

5(x + y = 15)

1(5x + 10y = 110)

5x + 5y = 75 .......... equation iii

5x + 10y = 110 ........ equation iv

Subtract equation iv from iii

-5y = -35

y = 35/5

y = 7

Number of adults is 7

Since x + y = 15

x = 15 - 7

x = 8

Number of children is 8
