Answer:
80
Step-by-step explanation:
area of a trapezoid: (base1+base2)/2 * height
(3+17)/2 *8 = 10*8 = 80
A 2/3 (67%) chance, which is likely.
There are a total of 48 marbles. If you take out the white marbles, 32 out of the 48 total marbles are not white (32/48). Simplify the fraction and you get 2/3.
-4.5 - 4.2(-x - 5.5) = 3x
-4.5 + 4.2x + 23.1 = 3x
18.6 + 4.2x = 3x
subtract 4.2x from both sides of the equation
18.6 = -1.2x
divide -1.2 from both sides of the equation
-15.5 = x
