Answer:
-2 ≤ x < 12
Step-by-step explanation:
<u>-15x +4 ≤ 34</u>
Add 15x-34 to both sides
-30 ≤ 15x
Divide by 15
-2 ≤ x
__
<u>-6x +70 > -2</u>
Add 6x +2 to both sides
72 > 6x
Divide by 6
12 > x
__
The two solution spaces overlap. Since the AND of the two inequalities is involved, the solution of both is just that part of the number line where there is overlap.
The solution is ...
-2 ≤ x < 12
Simplifying
5m + -7 = 6m + -9
Reorder the terms:
-7 + 5m = 6m + -9
Reorder the terms:
-7 + 5m = -9 + 6m
Solving
-7 + 5m = -9 + 6m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-6m' to each side of the equation.
-7 + 5m + -6m = -9 + 6m + -6m
Combine like terms: 5m + -6m = -1m
-7 + -1m = -9 + 6m + -6m
Combine like terms: 6m + -6m = 0
-7 + -1m = -9 + 0
-7 + -1m = -9
Add '7' to each side of the equation.
-7 + 7 + -1m = -9 + 7
Combine like terms: -7 + 7 = 0
0 + -1m = -9 + 7
-1m = -9 + 7
Combine like terms: -9 + 7 = -2
-1m = -2
Divide each side by '-1'.
m = 2
Simplifying
m = 2
E all of these are hexahedra

Step-by-step explanation:
By order of PEMDAS, perform math within parentheses first.

Now, simply divide
Since 57x17=969 I did 969-942 and got 27 so there is 16 full rows and then 27 left over so that means it won’t be a full row but 27 extra seats will be filled. (If your wondering where the 17 came from that’s how many rows can be made that’s over 942 because if I did 57x16 it would equal 912 and I would not have had a full row of chairs)
