X+y=180
they are adjacent angles
x=50
y=130
Answer:
x=1.75 hour
Step-by-step explanation:
200km=2.5
140km=x
2.5 * 140=200x
350=200x
x=350/200
x=1.75
the time it will take is x=1.75 hour
Answer:
thank you so much i really need someone right now
Step-by-step explanation:
That is 100 choices for the first number
99 for the 2nd number
98 for the 3rd number
in total, there are 100*99*98 or 970200 possible combos of winning numbers
k = 18
the common difference d of an arithmetic sequence is
d = a₂ - a₁ = a₃ - a₂ = ....
a₂ - a₁ = 2k - 1 - k - 9 = k - 10 and
a₃ - a₂ = 2k + 7 - (2k - 1) = 2k + 7 - 2k + 1 = 8, hence
k - 10 = 8 ⇒ k = 8 + 10 = 18
the 3 consecutive terms are
27, 35, 43
