Answer:
Step-by-step explanation:
solve for x
8.6 + 5.6x - 1.5 = 40.7
5.6x = 40.7 - 8.6 + 1.5
5.6x = 33.6
x = 33.6 : 5.6
x = 6
-----------------------------
check
8.6 + 5.6 * 6 - 1.5 = 40.7
40.7 = 40.7
the answer is good
the entire walk is 9/7 hours i think
5/8
(sqrt)x -3=y
x=(y+3)^2
=
=y+3
-3=y
The <em>correct answer</em> is:
{3, 4, 5, 6, 7, 8, 9, 10, 11, 12} .
Explanation:
The sample space for rolling these two spinners is:
(1, 2), (1, 4), (1, 6), (1, 8)
(2, 2), (2, 4), (2, 6), (2, 8)
(3, 2), (3, 4), (3, 6), (3, 8)
(4, 2), (4, 4), (4, 6), (4, 8)
This gives us the sums:
3, 5, 7, 9
4, 6, 8, 10
5, 7, 9, 11
6, 8, 10, 12
As a set, these are:
{3, 4, 5, 6, 7, 8, 9, 10, 11 12}
