Do you know the tricks to multiplying variables?

Answer: x = $7, y = $6

Step-by-step explanation:

Let x be the cost of an adult ticket

Let y be the cost of a children's ticket

Translate these sentences to algebra:

At the circus, three adult tickets and five child tickets cost $51: 3x + 5y = 51

Five adult tickets and two child tickets cost $47: 5x + 2y = 47

Now we have two equations. Let's use substitution to solve.

3x + 5y = 51

3x = 51 - 5y

.: x = 17 - 5y/3

Now substitute this value of x into the second equation to find the numerical value of y:

5(17 - 5y/3) + 2y = 47

85 - 25y/3 + 2y = 47

-19y/3 = -38

-19y = -114

.: y = 6

Now find x:

x = 17 - 5y/3

x = 17 - 10

.: x = 7

So an adult ticket costs $7, and a child ticket costs $6 :)

Answer:67.6275

Step-by-step explanation:

Answer:

Subtract 8.9 from both sides.

Step-by-step explanation:

When isolating variables, we need to change the parity of the number or value we are taking away. If we subtract 8.9 from both sides, we will get r=8.5.

Answer:

-9, 3.5, -2.25, and -9

Step-by-step explanation:

I'm assuming you mean the opposite numerical value so, the opposite of a positive number is a negative one and vice versa.

The average speed is the ratio of the total distance to the total time. Then the average distance covered in one hour​ by the bus is 60 kilometers.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

[tex]\rm Speed = \dfrac{Distace }{Time }[/tex]

A bus traveled 63 km in the first hour 60 km in the second hour and 57 km in the third hour.

Then the average speed will be

[tex]\rm Average \ speed = \dfrac{Total \ distace }{Total \ time }\\\\\\Average \ speed = \dfrac{63 + 60 +57}{1+1+1}\\\\\\ Average \ speed = \dfrac{180}{3}\\\\Average \ speed = 60 \ km/h[/tex]

The average distance covered in one hour​ by the bus is 60 kilometers.

Answer: ANSWER*0.15 (15% is 15/100 or 0.15)

Step-by-step explanation:

An arithmetic sequence is a sequence where the difference between each consecutive term is the same.

The number of seats in the new black box is 294.

It is a sequence where the difference between each consecutive term is the same.

Example:

2, 4, 6, 8 is an arithmetic sequence.

We have,

Number of rows = 14

n = 14

a = 8.

d = 2

So,

The number of seats in the 14 rows is,

8, 10, 12, 14,.........

Now,

The sum of the arithmetic sequence.

= n/2 [2a + (n - 1)d ]

The number of seats in the new black box.

= 14/2 [ 2x8 + (14 - 1)2 ]

= 7 [ 16 + 26 ]

= 7 x 42

= 294

Thus,

The number of seats in the new black box is 294.

Step-by-step explanation:

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
