Answer:
2
Step-by-step explanation:
1/2x4=2
X = total boats
2/3x are white....so the remaining boats = 1/3x
5/8 of the remaining boats are blue.....5/8 * 1/3 = 5/24x are blue
2/3 + 5/24 = 16/24 + 5/24 = 21/24 are blue and white......so 3/24 are red
3/24x = 6
x = 6 * 24/3
x = 144/3
x = 48 total boats in the marina <==
2/3(48) = 32 white
5/24(48) = 10 blue
3/24(48) = 6 red
Because the triangles are similar, corresponding sides have the same ratio.
.. AB/DE = BC/EC = AC/DC
.. 24/18 = 8/y = (15 +x)/15
Then we can solve for x and y.
.. x = 15*(24/18) -15 = 5
.. y = 8*(18/24) = 6
Which set of ordered pairs represents a function? \{(5, -2), (0, 3), (-4, 6), (0, 5)\}{(5,−2),(0,3),(−4,6),(0,5)} \{(5, 7), (5,

Answer:
(-5, -9), (8, -4), (-4, -3), (4, -4)
a function does not have a repeating domain or x. hope this helps.
Answer:
Step-by-step explanation:
first one is true because rational numbers are numbers that can be expressed in the form a/b where a and b are integers
second - not true because 17.5 can be expressed as a fraction which is 175/10
third - not true because square root of 6 cannot be expressed in the form a/b
fourth - true
fifth - not true
