Let the numbers be x and y
x + y = 57 ........(i)
x - y = 13 ........(ii)
Add equations (i) and (ii) to eliminate y
x + y + x - y = 57 + 13
x + x + y - y = 57 +13
2x = 70
x = 70/2 = 35
From (i) x + y = 57
35 + y = 57
y = 57 - 35
y = 22
The numbers are 35 and 22.
Answer: Hello, it would be 3(x-2)^2-(x-5)^2
Step-by-step explanation:
Let x be the daily fee
0.5(48) +x = 64 is the equation,
Multiply:
24 + x = 64
Subtract:
x=40
The daily fee is $40
Hope this helps
