Answer:
18.75 or 18 3/4
Step-by-step explanation:
You can set up a system of equations for this problem. x= number of coach tickets and y = number of first class tickets.
$210x + $1200y = $10,230 (cost of coach ticket plus cost of first class tickets is total budget)
x + y = 11 (number of coach tickets plus number of first class tickets is total number of people)
Solve the second equation for y to get y = 11 - x, then plug that into the first equation and solve for x:
$210x + $1200(11 - x) = $10,230
$210x + $13,200 - $1200x = $10,230
-$990x + $13,200 = $10,230
-$990x = $2,970
x = 3
Sarah bought x = 3 coach tickets. Plug that into the second equation and solve for y:
3 + y = 11
y = 8
Sarah bought y = 8 first class tickets.
Answer:
x=20
Step-by-step explanation:
x-15=5
x=5+15
x=20
X= 41.666666 repeating. not sure if you wanted the (x)(3) or if you meant x cubed, so x^3
To compare fractions with unlike denominators convert them to equivalent fractions with the same denominator. Compare fractions: If denominators are the same you can compare the numerators. The fraction with the bigger numerator is the larger fraction.
