The area of an airplane's wings is related to the airplane's lifting force, which holds the
airplane in the air. the table below lists several wing areas and the corresponding
lifting forces.
airplane lifting force
area of wings
(square feet)
125
lifting force
(pounds)
1,875
150
2,250
175
2,625
250
x
420
3,750
5,625
y
the ratio of lifting force to area is equivalent for all pairs in the table. what are the
values of x and y?
a x = 375 square feet and y = 7,500 pounds
b x = 335 square feet and y = 7,500 pounds
c x = 375 square feet and y = 6,300 pounds
d x = 335 square feet and y = 6,300 pounds

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
