I think the answer would be 31°
Step-by-step explanation:
ok, so the plot starts at 0,0. ok?
YOU ARE GOING TO GO UP 5, OVER 4.
CLEAR?
Answer:
11
Step-by-step explanation:
The two equations appear to be ...
- 12x +4y = 152
- 32x +12y = 420
These can be solved for y using Cramer's rule:
y = (152(32) -420(12))/(4(32) -12(12)) = -176/-16 = 11
The cost of the vegetarian lunch is 11.

<em>Comment on Cramer's Rule</em>
For equations ...
ax +by =c
dx +ey = f
The solutions are ...
x = (bf -ey)/(bd -ea)
y = (cd -fa)/(bd -ea) . . . . note the denominators are the same expression
Once you memorize the pattern of products, this can be the simplest way to solve a pair of equations--especially if you only need one of the variable values.
So the area of a circle is πr²
if the diameter of the sign 30 in then the radius is 15 in
Now Area of Circle = π(15 in)²
= 706.86
Thus by estimation the best answer is OPTION C
It's b. An empty circle refers to greater than.
