Answer:
Total distance mouse traveled in 3 hours = 
of a mile
The mouse traveled the same distance in each hour. So in order to find the distance covered in 1 hour we have to divide the distance covered in 3 hours by 3. This will give us the distance that the mouse traveled in one hour.
So, the distance traveled in one hour will be = 
of a mile
The error which Matt made was that he divided only the denominator of the expression by 3, this probably was a calculation error.
Correct conclusion will be: Mouse travel 1/24 of a mile each hour
Answer:
x=1
Step-by-step explanation:
-3x(5-4)+3(x-6)
-15x+12x+3x-18
-3x+3x-18
-18=-12x-6
-12x=-18+6
-12x=-12
12x=12
x=12/12
x=1
$7.20 $28.8 $18.8 $225.6 $225.6
4 $10 12 .25 $56.4
X___ -_____ X____ X_____ +_____
$28.8 $18.8 225.6 $56.4 $282
You multiply $7.20 by the 4 hours she's working and you'll get $28.80. Then you would subtract the $10 from your answer and get $18.80. Then you'd multiply $18.80 by 12 for the mouths she's working and get $225.60. Next you multiply $225.60 by .25 from the grandparents and get $56.40. Finally you add $225.60 to $56.40 and get $282 in her savings account.
D + 3r = 15
d = r + 3
r + 3 + 3r = 15
4r + 3 = 15
4r = 15 - 3
4r = 12
r = 12/4
r = 3 ....he bought 3 roses, at $ 3 per rose = $ 9 <==
d = r + 3
d = 3 + 3
d = 6....he bought 6 daisies, at $ 1 per daisy = $ 6
