Probability always adds up to 1 so, if there is only one choice, the chance that it will happen is 100% (1 out of 1) so true
Hope this helps! :)
Answer:
1 1/2 or 1.5
Step-by-step explanation:
trapezoid area formula: a = (a+b/2) x h
bases: 8 + 4 = 12
12/2=6
6 x 1/4 = 1.5 or 1 1/2
P = 2(L + W)
P = 34
L = W + 5
34 = 2(W + 5 + W)
34 = 2(2W + 5)
34 = 4W + 10
34 - 10 = 4W
24 = 4W
24/4 = W
6 = W <==== the width is 6 ft
L = W + 5
L = 6 + 5
L = 11 <==== the length is 11 ft
It depends on the systems of equations. I would stay away from elimination, go for substitution and graph only if asked.
