Answer:
There are 49 white marbles.
Step-by-step explanation:
w + g = 62 (w = white and g = green marbles).
w = 4g - 3
w - 4g = -3 Subtract this equation from the first equation:
g - (-4g) = 62 - (-3)
5g = 65
g = 65/5 = 13.
So w = 62 - 13 = 49.

Answer:
A) (Triangle) So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Example: Find the area of the triangle. The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.
B) We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius.
C)The parallelogram area can be calculated, using its base and height.
Area = ½ × d1 × d2 sin (y)
All Formulas to Calculate Area of a Parallelogram
Using Base and Height A = b × h
Using Trigonometry A = ab sin (x)
Using Diagonals A = ½ × d1 × d2 sin (y)
D)Area of a trapezoid is found with the formula, A=(a+b)/2 x h. Learn how to use the formula to find area of trapezoids.
Hope this helps!
