BRAINLYYYY PLUS 100 PointsThe difference between two numbers is 84 and their sum is 278. What are the numbers? Hint( answer is x
den301095 [7]

Answer:

x = 181 and y = 97

Step-by-step explanation:

let called the first number is x

the second number would be called y

We are given that:

x + y = 278 (1)

x = y + 84 (2)

Let change x in (2) into (1):

y + 84 + y = 278

2y + 84 = 278

Subtract 84 from both side, we got:

2y + 84 - 84 = 278 - 84

2y + 0 = 194

Divide both side by 2, we got:

2y / 2 = 194 / 2

y = 97

Because y = 97 and x + y = 278 so x would equal:

x + 97 = 278

Subtract 97 from both side, we got:

x + 97 - 97 = 278 - 97

x + 0 = 181

x = 181 and y = 97

Hope this helped :3

For a concert, there are $50 reserved seat tickets and $35 general admission tickets. there are 2000 reserved seats available, a
nevsk [136]

The number of seats sold cannot be negative, so you have

... x ≥ 0, y ≥ 0

The limits on numbers of seats must be observed, so you have

... y ≤ 2000

... x + y ≤ 3000

And the revenue constraint must be met:

... 35x + 50y ≥ 90,000

Together, these inequalties are ...

{x ≥ 0, y ≥ 0, y ≤ 2000, x + y ≤ 3000, 35x + 50y ≥ 90,000}
