Answer: A cherry pie costs 9 and an apple pie cost 12
Step-by-step explanation:
Let an apple pie be represented by a
Let an cherry pie be represented by c
Jennifer sold 12 cherry pies and 3 apple pies for a total of 144. This can be written as:
12c + 3a= 144
Jacob sold 2 cherry pies and 9 apple pies for a total for 126. This can be written as:
2c + 9a = 126
12c + 3a= 144 ............. i
2c + 9a = 126 ........... ii
Multiply equation i by 2
Multiply equation ii by 12
24c + 6a = 288 ........ iii
24c + 108a = 1512 ...... iv
Subtract iv from iii
-102a = -1224
a = 1224/102
a = 12
An apple pie costs 12
From equation i
12c + 3a= 144
12c + (3×12) = 144
12c + 36 = 144
12c = 144 - 36
12c = 108
c = 108/12
c = 9
A cherry pie costs 9
It would be a right scalene triangle.
hope this helped :)
I think its x=<span><span>−3</span>+<span><span><span><span><span>√11</span></span> or </span></span>x</span></span>=<span><span>−3</span>−<span>√<span>11</span></span></span>
Answer:
I feel like my answer is wrong but all of them are false
first one: it's between 0 and 5
second one: it's between 5 and 10
third one: it's between 10 and 15
but you could also say that they are all true because between the numbers they gave, they are doing what they said
<em>Hope this helps</em>
