Answer:
there will be 537 items in the library
Step-by-step explanation:
If m= a number that can be square rooted to give a whole number
x = -2
y = 1
let's multiply second equation by 4 to get a common coefficient of y variable.
16x-8y=-40
add the equations
3×+8y=2
16x-8y=-40
----------------
3x+16x = -38
19x = -38
x = -2
substitute x
3×-2 + 8y = 2
-6 + 8y = 2
8y = 2+6
y = 1
check the answer
-6+8 = 2
-8-2= -20
I did x - 10 =290
+10 +10
-------------
x = 300 so they took $1.00 a day
