Caleb and Landon work at a dry cleaners ironing shirts. Caleb can iron 30 shirts per hour, and Landon can iron 15 shirts per hou

Hitman42 [59]

Answer:

The system of the equations is x - y = 2, 2x + y = 22, where x is the number of hours that Caleb worked and y is the number of hours that Landon worked

Step-by-step explanation:

Assume that Caleb worked for x hours and Landon worked for y hours

∵ Caleb worked for x hours

∵ Landon worked for y hours

∵ Caleb worked 2 more hours than Landon

→ That means Caleb hours = Landon hours + 2

∴ x = y + 2

→ Subtract y from both sides

∴ x - y = 2 ⇒ (1)

∵ Caleb can iron 30 shirts per hour

∵ Landon can iron 15 shirts per hour

∵ They ironed 330 shirts between them

→ Multiply x by 30 and y by 15, then equate their sum by 330

∴ 30x + 15y = 330

→ Divide both sides by 15 to simplify the equation

∴ 2x + y = 22 ⇒ (2)

The system of the equations is x - y = 2, 2x + y = 22, where x is the number of hours that Caleb worked and y is the number of hours that Landon worked

Which of the following illustrates the truth value of the given conditional statement? p: 2 + 2 = 4 q: 7 + 1 = 7 T F → F T T → T

musickatia [10]

Answer:

T F → F is the correct answer.

Step-by-step explanation:

In the given question if p illustrates p: 2 + 2 = 4

which is true so the truth value of this statement p is True.

Now the other statement q illustrates q: 7 + 1 = 7

Which is a false statement so the truth value of this statement is False.

As we know when "p→q ( p implication q), the truth value of implication is False only when truth value of p is True and for statement q the truth value is False."

We can see from the truth table truth value of p→q will be False.

So T F → F
