210 take 126/3 = 42 take 42x5 = 210
Answer: x= -6; y= -1
Step-by-step explanation:
-4x + y = 23
4x - 9y = - 15
-4x + y = 23
y = 23 + 4x [Add 4x to both side]
4x - 9(23 + 4x) = - 15
4x - 207 - 36x = - 15
-32x - 207 = -15
-32x = 192 [Add 207 to both side]
x = -6 [Divide -32 from both side]
-4x + y = 23
-4(-6) + y = 23 [Plug in -6 for x]
24 + y = 23 [Subtract 24 from both side]
y = -1
Answer:
24 in

The exhibition of 7 birds will cost $2,450
<h3>
How to calculate the total cost ?</h3>
The wildlife center charges a basic fee of $325 for a bird exhibition
When 5 birds were exhibited, $125 additional fee was charged
The additional fee for a bird is
= 125/5
= 25
Therefore the total cost of exhibiting 7 birds can be calculated as follows
= 325 + 25
= 350
350 × 7
= 2,450
Hence the total cost for the exhibition of 7 birds is $2,450
