The cost of admission to a popular music was $162 for 12 children and 3 adults. The admission $122 for 8 childern and 3 adults in another music concert. For extra credit (10 pts), how much was the admission for each child and adult? Write the equation

Answers

Answer 1

Answer:

Step-by-step explanation:

let the number of children be x

and the number of adults be y

12x+3y=162-----1

and

8x+3y=122------2

equating both 1 and 2 we have

12x+3y=162-----1

8x+3y=122------2

subtract 2 from 1 we have

12x+3y=162-----1

- 8x+3y=122------2

4y+0=40

4y=40

y=40/4

y=10

put y=4 in eqn 1 we have

12x+3y=162-----1

12x+3*10=162-----1

12x+30=162

12x=162-30

12x=132

x=132/12

x=11

therefore a child will cost $11 and adult will cost $10

Y= 5(2) = 10

y= 5(3) = 15

y= 5(4) = 20

y= 5(5) = 25

y= 4(1)+3 = 7

y= 4(2)+3 = 11

y= 4(3)+3 = 15

The point-slope form of the equation of the line that passes through (-9, -2) and (1, 3) is y-3 = {(x - 1). What is
the slope-intercept form of the equation for this line?

Answers

Answer:

u of the record for me and my family are doing well and that you have a meeting with the record for me and my family are doing well and that you have

Answer:

Step-by-step explanation:

Just rewrite y-3 = {(x - 1) as y-3 = m(x - 1). {(x - 1) is not valid.

Next, solve this y-3 = m(x - 1) for y:

Adding 3 to both sides yields y = m(x - 1) + 3, or:

y = mx - m + 3, or

y = mx + (-m + 3). This is in slope-intercept form.

If you choose m = 2, then the equation becomes

y = 2x +(-2 + 3), or:

y = 2x + 1

Note: to get a single answer to this question you must provide the m value.

The solution of the given inequality is m>12.

The given inequality is 6 < m/2.

What is a inequality?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given inequality can be solved as follows:

6 < m/2

Multiply 2 to the given inequality.

That is, 6 × 2 < m/2 × 2

= 12<m

= m>12

Therefore, the solution of the given inequality is m>12.

A rectangular section of wilderness will be set aside for a new wildlife refuge. It's dimensions are 5.2 × 105meters by 3.7 × 106meters. Find the area of the land in square meters.

Answers

Answer:

19.24*10^11meters

Step-by-step explanation:

Given the dimensions are

length= 5.2 × 10^5meters

width= 3 .7 × 10^6meters

We know that area is given as

Area=length * width

Area=5.2 × 10^5* 3 .7 × 10^6

Area= 5.2*3.7*10^5+6

Area=19.24*10^11meters

Therefore the area is 19.24*10^11meters

A packet of crisp weighs 32 grams to the nearest gram. a multi-pack crisp contains 10 packets. work out the least and the greatest weighs of the multipack. ignore the weight of the multipack

Answers

Answer:

Least weight of multipack :

31.5 * 10 = 315g

Highest weight of multipack :

32.4 * 10 = 324g

Step-by-step explanation:

Weight of a packet of crisp to the nearest gram = 32 g

The least value of the weight of actual packet = 31.5 (least number which can give 32 when rounded to the nearest gram)

The highest value of the weight of actual packet = 32.4g (Highest number which can give 32 when rounded to the nearest gram)

Since a multipack contains 10 packets of crisp :

Least weight of multipack :

31.5 * 10 = 315g

Highest weight of multipack :

32.4 * 10 = 324g
