GIVING BRAINLEIST Mason has four times as many stamps in his collection as
his friends Ferdinand and Leonard combined. Ferdinand
has 9 stamps in his collection. Mason has 76 stamps in
his collection. How many stamps does Leonard have in his
collection?
The equation 4(x + 9) = 76 models this situation. Which choice shows the
sequence of operations needed to solve this problem, using both arithmetic
and algebra?

I've been working on this for a few days and i just don't understand, it's due in a few hours. you.the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case.part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
