Answer:

$160$ °

Step-by-step explanation:

An alternative method is to use the exterior angle.

the sum of the exterior angles is ALWAYS 360 °

So you can find the size of the exterior angles of a regular polygon quite easily:

If there are 18 sides ( n = 18 ) , then each exterior angle is:

$\frac{360}{n} =\frac{360}{18} = 20$ °

The sum of the exterior and interior angles is 180° because they are adjacent angles on a straight line.

∴ each interior angle is 180° - 20° = 160°

Solve 5c + 4 = -26

mr_godi [17]

<em>1) 5 c + 4 = - 26
5 c = -26 -4
5 c = -30
c = -30 / 5
c = -6 so correct option is B..

2) 3 x - x +2 = 12
2 x +2 = 12
2x = 12-2
2x = 10
x = 10/2
x= 5 so correct option is D

3 ) 3 ( x + 1 )+ 6 = 33
3x + 3 + 6 = 33
3x + 9 = 33
3x = 33-9
3x = 24
x = 24/3
x = 8 so correct option is B

4) y/-6=9
y=9 x -6
y= - 54 there is no such option i guess question is missing

5)(x + 4) /2 = 7
x +4 = 7 x 2
x + 4 = 14
x = 14-4
x = 10 so correct option is D

6)1/3 ( 2x - 8) = 4
2x/ 3 - 8 /3 = 4
2x - 8 / 3 = 4
2x - 8 = 4 x 3
2x - 8 = 12
2x = 12 + 8
2x = 20
x = 20/2
x = 10 so correct option is C

Using the given functions, it is found that:

Lower total cost at Jump-n-Play: 40, 64.

Lower total cost at Bounce house: 28, 8, 30.

Same total cost at both locations: 32.

<h3>What are the cost functions?</h3>

For n visits to Jump-n-play, the cost is:

J(n) = 189 + 3n.

For n visits to Bounce Word, the cost is:

B(n) = 125 + 5n.

Comparing them, we have that:

$J(n) < B(n)$

$189 + 3n < 125 + 5n$

$64 < 2n$

$n > 32$

Hence:

For less than 32 visits, the cost at Bounce World is lower.

For more than 32 visits, the cost at Jump-n-play is lower.

Hence:

Lower total cost at Jump-n-Play: 40, 64.

Lower total cost at Bounce house: 28, 8, 30.

Same total cost at both locations: 32.

In two or more complete sentences explain how you would set up and solve the following equation: Peter opened his account with $

Lilit [14]

What you would do is you would keep subtracting (I recommend a calculator for this task) from both accounts until you get an equal amount for each. You would also have to record this down that way you know each time what you got. (And please do not put the calculator part). Really hope this helps!!!
