I’m pretty sure it’s B. -3/8x - 1/4 :).
X is 180 - 30 = 150,
The sum of the sides of a polygon is the (number of sides - 2) * (180) so the total interior angle measure of the right polygon is 360.
360 = 80 + 90 + 150 + y
x = 150
y = 40
Answer:
48
Step-by-step explanation:
let the number be x and x + 16 the result of adding 16 to it, then
the ratio of the result to the original is
= 
( cross- multiply )
4x = 3(x + 16) = 3x + 48 ( subtract 3x from both sides )
x = 48
1 = 60
2 = 120
3 = 25
triangles have total angles of 180 40+80=120
180-120=60
straight lines have total angles of 180
180-60=120
triangles have total angles of 180
120+35=155
180-155=25
Answer:
3012 books
Step-by-step explanation:
Let y = number of books produced and sold
Total cost = Fixed cost + Variable cost = 32379 + 10.75*y
Total sales = 21.50*y
Set these equal to each other and solve for y
21.50*y = 32379 + 10.75*y
10.75*y = 32379
B = 3012
The publisher must produce and sell 3012 books.
