Answer:
2
Step-by-step explanation:
12x+6=20-10 (subtract 6 to -10)
12x=20x+-16 (subtract 20)
-8=-16 (divide -16 by -8)
x=2
Answer:
125 traffic cones
Step-by-step explanation:
In order to find the total number of meters, we can set up a proportion to find based on the ration of cm to m:
, where 'x' is the number of meters
cross-multiply: x = 25(50) or x = 1250 m
Since there is a cone every 10 m, we can divide the total number of meters by 10:
1250/10 = 125 cones
Answer: a
Step-by-step explanation:
y = x means that the line is going 1 value of x for every 1 value of y.
The intersection would be at the (0,0).
However, y = x+2 would have a intersection at (0,2) when y-axis have the value 2. The slope doesn't increase, because the derivative of both slopes gives us y = 1.
Therefore, the line shifts up 2 units.
Hope you understood!
Good luck ;)

Sin 30=opposite side/hypotenuse =8/x
1/2=8/x so 1•x=2•8; x=16
Sin60= opposite side/hypotenuse=y/16
(Sqrt 3)/2=y/16 so 2•y=16• sqrt 3; y=13.856
