Answer:
Step-by-step explanation:
w + g = 52
w = 4g - 3
(4g - 3) + g = 52
5g - 3 = 52
5g = 52 + 3
5g = 55
g = 55/5
g = 11....there are 11 green marbles
w + g = 52
w + 11 = 52
w = 52 - 11
w = 41 <=== there are 41 white marbles
<h3>Answer:</h3>
4 m
<h3>Explanation:</h3>
We know that a triangle has half the area of a rectangle of the same height and width. That is, the rectangle that is as high and wide as the sail will have an area of 8 m². Of course, the area of a rectangle is the product of its length and width.
We know that 2×4 = 8 and that 4 is twice as much as 2. Thus the 4 dimension corresponds to the height of the sail, and the 2 dimension corresponds to its width.
The sail is 4 m high.
