The height of emperor penguin is 120 cm and height of galapagos penguin is 49 cm

Solution:

Given that The largest species of penguins is the emperor penguin. One of the smallest is the Galápagos penguin

To find: height of each penguin

From given question,

Let "e" be the height of emperor penguin

Let "g" be the height of galapagos penguin

Total height of two penguins = 169 centimeter

Therefore,

height of emperor penguin + height of galapagos penguin = 169

e + g = 169 ---- eqn 1

The emperor penguin is 22 centimeters more than twice the height of the Galápagos penguin

height of emperor penguin = 22 + 2(height of galapagos penguin)

e = 22 + 2g --- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

g = 169 - e ------- eqn 3

Substitute eqn 3 in eqn 2

e = 22 + 2(169 - e)

e = 22 + 338 - 2e

e + 2e = 360

3e = 360

Thus from eqn 3,

g = 169 - 120

Thus height of emperor penguin is 120 cm and height of galapagos penguin is 49 cm

A 5000-seat theater has tickets for sale at $28 and $40. How many tickets should be sold at each price for a sellout performa

Kamila [148]

Answer:

Let's denote:

x: number of ticket 28$

y: number of ticket 40$

Then, we have:

x + y =5000

28x + 40y = 153200

=> 28(5000 - y) + 40y = 153200

=> 12y = 153200 - 140000

=> 12y =13200

=> y = 1100 (ticket 40$)

=> x = 5000 - 1100 = 3900 (ticket 28$)

Use the distributive property to factor out y.

Kay [80]

________________________________

5y-3y+12

=2y+12

So the new expression becomes 2y+12

hope it helps

Good luck on your assignment
