50 *0.4 = 20 tables seat 2
50-20 = 30 tables seat 4
30*4 = 120
20*2 =40
120 +40 = 160 seats total
Step-by-step explanation:
(2x + 45)° and x° are supplmentary angles.
(Sum of angles on a straight line = 180°)
Hence 2x + 45 + x = 180, 3x = 135, x = 45.

The perimeter of the circle is 18.84 miles and area of the circle is 28.26 miles square.
<h3>What is the perimeter of the circle?</h3>
The perimeter of the circle that has a radius of r is defined as the product of diameter to the pie value.
The perimeter of the circle = 2πr
The perimeter of the circle = 2πr
The perimeter of the circle = 2 (3.14) (3)
The perimeter of the circle = 18.84 miles
Also,
The area of the circle =πr^2
= 3.14 (3)^2
= 28.26 miles square

Answer:
x = 10
Step-by-step explanation:
Let h(x) = -2x - 5. If h(x) = -25
-2x - 5= -25
Add 5 to each side
-2x-5+5 = -25+5
-2x = -20
Divide by -2
-2x/-2 = -20/-2
x = 10
