Q-2r=4, therefore: q=4+2r.
Plug the value of q into q+r=37, so you get:
4+2r+r=37
3r=37-4=33
3r=33
Therefore: r=11.
q-2r=4, but r=11, so:
q-2(11)=4
q-22=4
Therefore q=26.
Check if the answer is correct using second equation:
q=4+2r=4+2(11)=4+22=26.
So: q=26 and r=11.
Answer:
Step-by-step explanation:
root(23) - 8 < root(23) - 3 -3 is greater than -8
3 root(62) > 3 root(59) 62 > 59 Since the numbers are positive the roots of the larger number is going to be larger than the roots of the smaller number
-root(50) < - 3
The root of 50 is about 7. - 7 is smaller than - 3. Think money. Would you rather pay 3 dollars for a cup of coffee than 7 dollars for a cup of coffee?
root 15 + 2 < root(65) - 1
root(15) is roughly 4 when 2 is added to it, the result is about 6
root (65) is a touch over 8. When 1 is subtracted the result is about 7.
That's larger than the left side.

Question
--------------------------------------------------------------------
3x = 0.5x²
--------------------------------------------------------------------
Take out common factor , i.e. x
--------------------------------------------------------------------
3x = 0.5x²
3x - 0.5x² = 0
x(3 - 0.5x) = 0
--------------------------------------------------------------------
Use the Zero Product Property to solve for x
--------------------------------------------------------------------
x(3 - 0.5x) = 0
x = 0 or 3 - 0.5x = 0
x = 0 or 0.5x = 3
x = 0 or x = 3 ÷ 0.5
x = 0 or x = 6
--------------------------------------------------------------------
Answer: x = 0 or 6 (Answer D)--------------------------------------------------------------------

Answer – B (Tossing a coin)
A simple event is an event where only one experiment happens at a time (such as tossing a coin), and the event has only one outcome. When two events are occurring simultaneously(such as spinning a spinner and drawing a card from a deck of cards, drawing 3 cards from a deck of cards or tossing 4 coins), then it is no longer a simple event; it is a complex event.
