Step-by-step explanation:
A) x + y = 2
B) x * y = -8
B) y = -8 / x we can substitute this into equation A
A) x + -8 /x = 2 multiplying both sides by "x"
A) x² -8 = 2x
x² +2x -8 = 0
(x + 4) * (x -2)
The 2 numbers are -4 and 2
Answer:
<h2>6</h2>
Step-by-step explanation:
We know:
If a ≤ b ≤ c are the sides of a triangle, then a + b > c.
We have a = x, b = 2x and c = 15 cm.
Therefore x ≤ 15 and 2x ≤ 15 ⇒ x ≤ 7.5
Therefore we have the inequality:
x + 2x > 15
3x > 15 <em>divide both sides by 3</em>
x > 5 and x ≤ 7.5
Finally x = 6
<u>First what I did was take out the 5 dollars. So I did 25 minus 5. </u>
25 - 5 = 20
<u>Next, I divide the left over 20 dollars by 1.25 to see how many tokens Marco could buy. </u>
20 / 1.25 = 16
<u>Which i came up with 16. So Marco can buy 16 tokens and still have enough money to use to buy lunch. </u>

<u>HOPE THIS HELPS! :)</u>
