Answer:
A)
Step-by-step explanation:

Answer:
x = 8
Step-by-step explanation:
4x + 3 = 35
subtract 3 from both sides
4x + 3 - 3 = 35 - 4
4x = 32
divide both sides by 4
4x / 4 = x
32/4 = 8
we're left with x = 8
Answer:
9.5
Step-by-step explanation:
Step-by-step explanation:
4 hours + 8 hours = 12 hours total
50$ bonus - 164$ = 114$
144$ divided by 12 hours = 9.5

Answer: E. 99
Step-by-step explanation:
A composite number has more than two factors which means not only including 1 and itself, but at least one other.
factor of 29: 1, 29
factor of 41: 1, 41
factor of 71: 1, 71
factor of 79: 1, 79
factor of 99: 1, 3, 9, 11, 33, 99
Clearly 99 has more than two factors.
Hope this helps!! :)

Answer: 1440 degrees</h3>
===================================================
Explanation:
See the diagram below. It shows there are 10 sides, so n = 10.
We'll plug this value of n into the formula below to find the sum of all ten interior angles
S = sum of interior angles
S = 180(n-2)
S = 180(10-2)
S = 180(8)
S = 1440 degrees
---------------
A different approach:
Let's assume this polygon is a regular polygon. This means each angle is congruent to one another.
We have n = 10 sides, so each exterior angle is E = 360/n = 360/10 = 36 degrees.
Each interior angle adjacent to this 36 degree exterior angle is
180-E = 180-36 = 144 degrees
Since we have 10 equal angles of 144 degrees each, so overall the interior angles add to 10*144 = 1440 degrees
Side note: if this polygon is not a regular polygon, then this section does not apply. You would use the first method instead.
