What did each friend pay, where c is the cost of the trip, not including the tip.
1 / 3 ( c+7.00)=11.25
Multiply both sides by 3
c + 7 = 33.75
Subtract 7 from both sides
c = 26.75
Answer:
12.751
Step-by-step explanation:
13.9 - 1.149
--Subtract--
Use foil (first, outer, inner, last)
First terms: 3x * 6x = 18x²
Outer terms: 3x * 1 = 3x
Inner terms: -2 * 6x = -12x
Last terms: -2 * 1 = -2
Put all that together to get 18x² + 3x - 12x - 2
3x and -12x can be combined because they're like terms; 3x - 12x = -9x
So the final product is 18x² - 9x - 2
The third quartile of this data set is B. 24.
Let x be the side of your square. Use Pythagoras to find the side in the right triangle formed with 2 sides and the diagonals:
x² + x² = 34²
2x² = 34² = 1126
x² = 1126/2 = 578
and x =√578 = 17√2 ≈ 24 ft
H will need 24 x 4 = 96 ft
