Step-by-step explanation: Gooooooooooooogle
They are similar. Set the proportions equal to each other
(x + 8)/8 = (x+14)/12
Cross multiply
(x + 8)/8 (8)(12) = (x + 14)/12 (12)(8)
12(x + 8) = 8(x + 14)
Distribute the 12 and 8 to the corresponding monomials inside the parenthesis
12(x + 8) = 12x + 96
8(x + 14) = 8x + 112
12x + 96 = 8x + 112
Isolate the x. Subtract 8x from both sides and 96 from both sides
12x (-8x) + 96 (-96) = 8x (-8x) + 112 (-96)
12x - 8x = 112 - 96
4x = 16
Isolate the equal sign. Divide 4 from both sides
4x/4 = 16/4
x = 16/4
x = 4

4 is your answer for x

Answer:
160 miles
Step-by-step explanation:
Distance = speed × time
Speed 1 = 40miles/hr , speed 2 = 50 miles/hr
Time 1 = 3 hrs, time 2 = 4 hrs
Distance 1 = speed 1 × time 1
= 40× 3 = 120 miles
Distance 2 = speed 2 × time 2
= 50 × 4 = 200 miles
Average distance = (distance 1+distance 2 ) ÷ 2
Distance = (200+120) ÷ 2 = 320 ÷2
= 160 miles

There wouldn't be a solution: because both equations have the same slope of 3, they would be parallel to each other. The best graph to pick would be the one with two positive steep slopes that are 3 up every one to the right.
[tex] \sin( \binom{10\pi}{11}) = \sin( \binom{\pi}{11}) [\tex]
[tex] \sin( \binom{6\pi}{11}) = \sin( \binom{5\pi}{11}) [\tex]
