If two adults and three children go to the movies, it costs $31.50. If one adult and five children go to the movies, it costs $35.00. What is the cost of one adult movie ticket? $5.50 $6.50 $7.50

Answers

The adult ticket would cost $7.50

Answer:

The kids is 5.50 adult is 7..50

Step-by-step explanation:

we create an equation

2x + 3y =31.50

and

1x + 5y=35.00

1x is just x so we subtract 5y from both sides

x= 35.00-5y

fill x with 35.00-5y

2(35.00 - 5y) + 3y = 31.50

70.00 - 10y +3y = 31.50

-10y + 3y = -38.50

-7y=-38.50

-7y/-7= -38.50/-7

y=5.50

Help fill in the blanks plz

Answer:

a=(c+2b)/5

Step-by-step explanation:

Like terms in one side to subject a.

When exchanging sides make sure u do inverse operations. Therefore;

9a - 4a = c + 2b

5a = c + 2b

a = (c+2b)/5

Martin chose two of the cards below. When he found the quotient of the numbers, his answer was -16/9. Write the division problem that Martin solved

Answers

Answer:

The required division problem he must solve is:

$(2)/(3) / (-3)/(8) =(2)/(3)*(-8)/(3)=(-16)/(9)$

Step-by-step explanation:

Consider the provided information.

Martin chose two of the cards below. When he found the quotient of the numbers, his answer was -16/9.

As we know that the quotient of the number is a negative number.

Therefore, the sign of both numbers must be different,

Thus we can concluded he must select $(2)/(3)$ as one of the card, so that product is a negative number.

Let the selected card be x.

$(2)/(3) / x =(-16)/(9)\n\nx=(2)/(3)/(-16)/(9)\n\nx=(2)/(3)*(-9)/(16)\n\nx=(-3)/(8)$

Hence, the two cards should be $(2)/(3)$ and $(-3)/(8)$

The required division problem he must solve is:

$(2)/(3) / (-3)/(8) =(2)/(3)*(-8)/(3)=(-16)/(9)$

Light travels 300,000 km/s. The planet Mars is about 228,000,000 km from the sun. How would you find out how many minutes it takes light from the Sun to reach Mars?

Answers

Answer:

12.67 minutes

Step-by-step explanation:

Time taken is given by distance divided by speed

Given distance of 228, 000, 000 km and speed of light as 300, 000 km/s then time will be

Time=228, 000, 000/300, 000=760 seconds

Conversion

60 seconds make up 1 minute

760 seconds will be 760/60

Time=760/60=12.666666666666

Rounded off, this is 12.67 minutes
