Answer:

-66, 80

Step-by-step explanation:

Let x represent the first number. Then the second number is 14-x, and the difference is ...

x - (14-x) = -146

2x = -132 . . . . . . add 14, collect terms

x = -66 . . . . . . . . the first number

14-x = 14-(-66) = 80 . . . . . . the second number

Answer:

-66 & 80

Step-by-step explanation:

Let the two numbers be x and y

x + y = 14 (1)

x - y = -146 (2)

Adding (1) & (2),

2x = -132

x = -66

y = 14 - x = 14 - (-66) = 14 + 66

y = 80

How do you solve this problem? With work!!

Evgesh-ka [11]

You would put 9 times v because you are multiplying it to the 9 and you do not know what v is then you would divide it by 3 and get your answer so for example if you should have gotten 9 times v = 72 then 72 divided by 3 = 24 and 24 divided by 3 = 8

The cost of a ticket to the circus is $14.00 for children and $32.00 for adults. On a certain day, attendance at the circus was

Evgesh-ka [11]

400 children and 600 adults bought tickets.

Step-by-step explanation:

Given,

Cost of one child ticket = $14

Cost of one adult ticket = $32

Total attendance = 1000

Revenue generated = $24800

Let,

x be the number of children.

y be the number of adults.

According to given statement;

x+y=1000 Eqn 1

14x+32y=24800 Eqn 2

Multiplying Eqn 1 by 14

$14(x+y=1000)\\14x+14y=14000\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(14x+32y)-(14x+14y)=24800-14000\\14x+32y-14x-14y=10800\\18y=10800\\$

Dividing both sides by 18

$\frac{18y}{18}=\frac{10800}{18}\\y=600$

Putting y=800 in Eqn 1

$x+600=1000\\x=1000-600\\x=400$

400 children and 600 adults bought tickets.
