Answer:
B
Step-by-step explanation:
Xavier has the least amount of money, so the only answer putting Xavier first would make the most sense to pick.
X + y = 27
y = x + 3
x + (x+ 3) = 27
2x + 3 = 27
2x + 3 (-3) = 27 (-3)
2x/2 = 24/2
x = 12
x + 3 = y
12 + 3 = y
y = 15
x = 12, y = 15

Answer:
-5 coach tickets
-8 first class tickets
Step-by-step explanation:
let x be the number of coach tickets and y the number of first class tickets:

Given that coach tickets costs $260 each, and first class tickets $1080 and that the total fare budget was $9940:

#From equation i, make x the subject of the formula:

#Substitute x in ii;

Hence, Sarah bought 5 coach tickets and 8 first class tickets.
Answer is 12 sq feet
Step by step
Roof is 36” x 24” which is 3’ x 2’
So 3 x 2 = 6 multiplied by 2 sides of roof
Total is 12 sq feet
————-
I made the roof peak with a 3” overhang over the entrance
I made the roof overhang the sides with 4”
—————-
So to find the hypotenuse (diagonal of the roof) I used the Pythagorean theorem.
a^2 + b^2 = c ^2
15^2 + 13^2 = c^2
394 = c^2
Take square root of both sides
C= 19.8 rounded to 20
I then added 4” overhang to each side for total diagonal of 24”
