not a clue luv sorry xxxx
Answer:
(amounts could be:)
Katia: $3.50
Mateo: $1.75
Step-by-step explanation:
<em>Remember that a quarter = $0.25, 4 quarters = $1.00</em>
<h3>We know that they both have 38 quarters ($9.50) </h3>
<em>after an hour of playing games in the arcade, Katia has $1.75 more than Mateo</em>
lets say that Katia has <em>(random amount)</em><em>$3.50(14 quarters) </em>and Mateo has $1.75 less than that.
$3.50 - $1.75 = $1.75
<h3>Katia has $3.50 and Mateo has $1.75.</h3>
f(-9) means x is -9
Replace x with -9 and solve:
2/3(-9) - 6
Simplify:
-6 - 6 = -12
f(-9) = -12
30 + 1x = 18 + 5x
subtract 18 from both sides
30 - 18 + 1x = 18 - 18 + 5x
12 + 1x = 5x
subtract 1x from both sides
12 + 1x - 1x = 5x - 1x
12 = 4x
To clear the multiplication by 4, divide both sides by 4
12/4 = 4x/4
3 = x
