Answer:
x = 105
Step-by-step explanation:
the sum of all interior angles of any four-sided figure has 360 degrees
∡F and ∡H are equal
add all four expressions and set them equal to 360
x + (x + 5) +( x + 5) + (140 - x) = 360
combine like terms
2x + 150 = 360
2x = 210
x = 105
Answer:
8/3 or 2.6666
Step-by-step explanation:
You have divided the first equation by 3 -- all except the 8. So you must divide the 8 by 3 giving you 8/3 which is 2 2/3 or 2.66666
Answer (x - 2y) = 8/3
Answer:
The range is 40.
Step-by-step explanation:
Range is just the largest number minus the smallest.
70 - 30 = 40
Answer:
T = total #
T = 5 (to the aunt) + 1/2 (T - 5) (to his friends) + 1 (to his sister) + 4 (left)
T = 5 + 1/2 (T - 5) + 1 + 4
T = 10 + 1/2 (T - 5)
2T = 20 + (T - 5)
2T = 20 + T - 5
2T = 15 + T
T = 15
