Answer:
C) 4t + 5.75 = 65
Step-by-step explanation:
This equation is correct because it adds together the price of one popcorn and the price of the 4 tickets as 4t.
A and B are wrong because only t should be multiplied by 4, and D is wrong because it subtracts the price of the popcorn.
Let us say that the number of pens that Matt has is x.
Therefore the number of pen that Sarah has is:
Sarah pens = (5/4) (1/3) x = (5/12) x
So the total number of pens they have is:
total = x + (5/12) x = (17/12) x
Hence the fraction of Matts pen is:
fraction = x / [(17/12) x]
fraction = 12/17
Answer:
e = 7
Step-by-step explanation:
Eliminate parentheses using the distributive property.
18e -48 = 5e +43
13e -48 = 43 . . . . . . . . subtract 5e from both sides
13e = 91 . . . . . . . . . . . . add 48 to both sides
e = 7 . . . . . . . . . . . . . . divide both sides by 13

<em>Comment on equation solving</em>
If there are parentheses or fractions, it usually works well to eliminate those. The distributive property is used to eliminate parentheses. Fractions can be eliminated by multiplying the equation by the denominator. (We mean 'multiply both sides of the equation by the denominator'.) If you have excellent skill with arithmetic using fractions, you don't need to go to the trouble to eliminate them.
After the numbers in the equation are mainly integers or decimals, the next step is to look to see where the variable of interest is located. You want to do what it necessary to put all of the variable terms on one side of the equal sign, and everything else on the other side. The procedure generally is to decide what you don't want, and subtract that from both sides of the equation.
Finally, you divide by the coefficient of the variable, so the variable stands alone on one side of the equal sign. This shows you the solution.
