Answer:

The resulting equation is 2y-8 + 5y - 10 = 0

Step-by-step explanation:

For the following system, use the second equation to make a substitution for x in the first equation.

x + 5y - 10 = 0 first equation

x = 2y - 8  second equation

Now substitute the second equation in first equation

Replace x with 2y-8 in first equation

x + 5y - 10 = 0

2y-8 + 5y - 10 = 0

The resulting equation is 2y-8 + 5y - 10 = 0

emmainna [20.7K]

Answer

The owner lose is $100 .

Reason

As given

A man comes into a store and steals $100 from the register without the owner knowledge.

Comes back and buys $70 worth of stuff and the owner gives him $30 in change.

i.e First man steals $100  than give back to owner when he buys  $70 worth of stuff and  the owner gives him $30 in change.

Therefore the total owner lose is the sum of  $70 worth of stuff and  $30 in change.

Total owner lose = $70 + $30

                            = $100

Therefore the owner lose be  $100 .

Hence proved

The admission fee at a carnival fair is $4.50 for children
Romashka-Z-Leto [24]

Answer:

Adult=1,385.71

Children=814.29

Approximately

Adult=1386

Children=814

Step-by-step explanation:

c= number of children

a= number of adults

Admission fee for children=$4.50

Admission fee for adults=$8.00

Total attendees=2200

Total amount realized=$5050

We need two equations to solve the two unknowns

c + a=2200 (1)

4.50c + 8.00a=5,050 (2)

From (1)

c + a=2200

c=2200 - a

Substitute c=2200 - a into (2)

4.50c + 8.00a=5,050

4.50(2200 - a) + 8.00a=5050

9900 - 4.50a +8.00a=5050

Collect like terms

9900-5050= -4.50a+8.00a

4,850=3.5a

Divide both sides by 3.5

1,385.71=a

Substitute a=1,385,71 into (1)

c + a=2200

c+1385.71=2200

c=2200-1385.71

=814.29

c=814.29
