First isolate x by multiplying by x on both sides.  It will look like this:
(2/3)x=1.2
Then devise by (2/3) on both sides to get:
x= 1.2/(2/3)
The easiest way to get this is plug that into a calculator and get the answer:
x=1.8

Answer:
5 minutes 
Step-by-step explanation:
To get the response to this question, it would be required to convert both times to seconds alone.
For the first, the time It takes to flash is 1 minute 15 seconds which is same as 75 seconds 
For the second, it takes 1 minute 40 seconds which is same as 100 seconds.
Now to get the time they would flash together, we need to know their lowest common multiples. The values involved are 75 and 100. Thus, the lowest common multiple of both is 300.
This is equivalent to 300 seconds which is 5 minutes time

Answer:
The angle between the ramp and the horizontal is 11.54 degrees 
Step-by-step explanation:
Here, we want to get the angle between the ramp and the horizontal 
What we have to do here is to bring the measure of 2 m near to the edge leftwards, so we can have a right triangle 
Now, the angle we want to calculate is the angle that faces the measure 2 m
The given measure of 10 m will represent the hypotenuse of the right triangle 
The trigonometric ratio that links the hypotenuse and the opposite is the sine 
The sine is the ratio of the opposite to the hypotenuse 
Thus, we have it that;
sin theta = opp/hyp
sin theta = 2/10
sin theta = 0.2
theta = sin^-1 0.2
theta = 11.54
