Answer:
False
Step-by-step explanation:
Well to solve for z we single it out, distribute, use the communicative property, and combine like terms.
42 = -7(z - 3)42 = -7(z - 3)
Distribute
42 = -7z + 21*42 = -7z + 21
42 = -7z + 882 = -7z + 21
-42 to both sides
-7z + 840 = -7z + 21
-21 to both sides
-7z + 819 = -7z
+7z to both sides
819 = 0
<em>Thus, </em>
<em>the given equation is false.</em>

Answer:
X= 75, Y=30 there you go!

Answer:
D. no solution
Step-by-step explanation:
h-z=3(1)
h=3+z(minus z from both side)
put in the second equation
-3h,+3z=6(2)
-3(3+z)+3z=6
-9-3z+3z=6
-9=6( not true)
so the equation doesn't have a solution.
Answer:
(a) 0.6
(b) 0.4
Step-by-step explanation:
If I am reading the little table right, You have made 9 shots, and have missed 6 of them. Therefore, in total, you have made 
shots.
The definition of probability is the number of events of a desired outcome divided by the total number of outcomes. Since you wish to make a shot for part a, the number of desired outcomes thus far is 9, out of 15 total shots. Thus,
making a shot
Since making a shot and not making a shot are mutually exclusive events, and the only two events that could occur when shooting a basket, the probability of not making a shot and the probability of making a shot are all of the possible outcomes, and is thus equal to 1.

QED
<h3>
Answer: 1260</h3>
====================================================
Work Shown:
n = number of sides = 9
S = sum of the interior angles of any polygon with n sides
S = 180(n-2)
S = 180(9-2)
S = 180(7)
S = 1260
