The cost of an apple pie is $13 and a blackberry pie is $18.
<h3>How to find the cost?</h3>
Let A be apple pies and B be blackberry pies.
3A + 11B = $237
3A + 12B = $255.
On solving the quadratic equation, we get
-B = -18
Therefore,
B = 18
Substitute B in any one of the equations,
3A + 11*18 = 237
3A = 237 - 198
A = 39/3
A = 13
The cost of an apple pie is $13 and a blackberry pie is $18.

Answer:
not similar
Step-by-step explanation:
For the triangles to be similar, at least two angles must match. Here, there is an 81° angle in both triangles. This means the sum of the remaining two angles must be ...
180° -81° = 99°
If the missing angle in either triangle matched the other given angle in the opposite triangle, the sum of those would be 60° + 40° = 100°, not 99°. This triangle pair does not have two matching angles, so the triangles are not similar.
ABC angles: 60°, 81°, 39°
FED angles: 59°, 81°, 40°

Write down some equations that express what you know.
A = 2*30 + 3x
K = 1*30 + 5x
A+K = 210
Substitute the expression for A in the A+K=210 expression
2*30 +3x + K = 210
Now substitute the expression for for K
2*30 + 3x + 1*30 + 5x = 210
Multiply and combine terms
60 + 3x + 30 + 5x = 210
90 + 8x = 210
Subtract 90 from both sides
8x = 120
Divide both sides by 8
x = 120/8 = 15

Answer:
B
Step-by-step explanation:
To select the correct equation, check to see that the c term of is 2 since the y-intercept is (0,2). This means only A and B are options since C and D have -2.
For A and B, substitute the other two points (-2,8) and (1,5) into the equations and see if it hods true.
This is not 8 and is not true.
This is true. This is the solution.
-6+3-3(-18)
Okay.
Work from left to right.
-6 plus 3 equals -3.
(Think of it as in a number line, from the spot of -6, move right three units. This will give you -3. Anyways..)
Now you have -3-3
The result is -6.
-6(-18)
Negative six times negative eighteen equals positive 108.
The answer is 108.
