180 because 30/180 can be simplified to 1/6 by dividing both numerator and denominator by 30
5 because 5/30 can be simplified to 1/6 by dividing both numerator and denominator by 5
Answer:
It will take 12 hours
Step-by-step explanation:
Distance equals rate times time
d = rt
We know the distance and the rate
240 = 12 * t
Divide each side by 12
240/12 = 12t/12
20 = t
It will take 12 hours
The sentence "15% of 4x is 20 less than x"
translates to 0.15 • (4x) = x – 20
Solving that…
0.15(4x) = x - 20 multiplipy 0.15•4
0.6x = x - 20 subtract x from both sides
-0.4x = - 20 divide both sides by -0.4
x = 50
Answer:
The maximum amount of money the chemistry club can spend without going over their buget is $81.4 ... With a total of 6 hours their allowed to use the room for.
Step-by-step explanation:
$49 is our constant and will not change. 5.40 however will. Let's use variable h for the amount hours they can rent the room for. Now we can make an inequality;
49+ 5.40h < 86.80
5.40h < 86.80
5.4h< 37.8
h< 7
Now that we know h will have to be less than seven for the chemistry club to spend less than their buget we can find that 6 is the maxium amount of hours they can spend in the room while staying within their budget.
(This answer does not consider decimals or half hours)
