5x + 2y = -10 general line equation form is: y= mx + c so 2y = -10 - 5x y = -2.5x - 5 m refers to gradient and c is offset on the y axis so gradient is -2.5 (gradient means slope)

The mean of a set of numbers is the average. That is to say, all the numbers added together and divided by the number of the numbers. the answer is 30.5
10 + 10 + 10 + 5 + 5 +1 = 41.
10 X 10 = 100 You can do this four ways: You can do it mentally in your head or you can add them all up on paper by lining up the numbers correctly with each other. You can use a calculator and that is the easiest way. An alternate way is to multiply 10 by 10.
Gradient = 2
The wind at a standard height of 10 m 33 ft above ground. Differs from the geostrophic wind and the gradient wind because of friction with the Earth's surface.

There is only one line in the x-y plane and that is a straight line with a gradient of -1, passing through the point (0, 10)

700.
10 + 10 + 10 + 10 + 10 + 10 + 10 + 108 = 178
10 + 10 + 10 + 10 + 10 = 50
10 + 10 + 10 + 10 + 10 + 10 = 60 10 X 6 = 60
4a + 6 - 4a = -10 Combining like terms: 6 = -10 or 4 = 0 which is FALSE. So the solution set is empty.
10 + 10 + 10 + 10 = 40
