Answer:

She needs 120 more dollars in order to purchase the calculators for her math class

Step-by-step explanation:

In order to solve this you have to find how much money 30 calculators are worth (30*14.00=420) which when subtracted from the amount she has in her account, (300) you can then subtract 420-300 to give you the answer of $120 more dollars

Lee likes to water ski on his brother's boat and plans to ski for two days in a row. The boat takes two gallons of gas each hour
riadik2000 [5.3K]

Answer:

120 dollars

Step-by-step explanation:

6 hours per day, for 2 days, leads to a total of 12 hours (2*6 = 12)

If it takes 2 gallons of gas to run the boat for 1 hour, then it will take 24 gallons to run for 12 hours. We can see this if we have the ratio below

2 gallons: 1 hour

12*(2 gallons): 12*(1 hour) .... multiply both sides by 12

24 gallons: 12 hours

Now multiply this gallon count (24) by the cost per gallon ($5) and we get to 5*24 = 120

Answer please in less that 10 minutes​
Andreyy89

Answer:

Step-by-step explanation:

Since we have an x under that radical, we have to get it out from under there.  To do that, do the opposite of the square root, which is to square.  But because this is an equation, you have to do the same thing to both sides.  Doing this gives you

6x-9=x^2

Get everything on one side and set the quadratic equal to 0 and solve for x:

x^2-6x+9=0

Factor this into 2 factors of (x - 3)(x - 3) = 0.  As you can see they are both the same, so x - 3 = 0 and x = 3.  That's your answer.  x = 3.
