Answer:
48f^2-110f+63
Step-by-step explanation:
We multiple every part of first sum with every prt of the 2nd sum:
(6f-7)(8f-9)=48f^2-54f-56f+63=
48f^2-110f+63
5.09 times 15 equals 76.35
Answer:
$1779.896
Step-by-step explanation:
From the above question
1 liter = $143.54
12.4 liters = $x
Cross Multiple
1 liter × $x = 12.4 liters × $143.54
$x = 12.4 liters × $143.54/1 liter
$x = $1779.896
Therefore, the total cost for Stacy gas in dollars and cents is $1779.896
Answer:
1 2/21
Step-by-step explanation:
We start out with:
3/7 + 2/3
In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:
3/21 + 2/21
But what about the numerators? You do the same thing as before (multiplying by the other's denominator). Now we have:
9/21 + 14/21
We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:
1 2/21!
