Answer:
I think it should be 5y+24
Answer:the first ans (f(x)=(1/x+2)+3
Step-by-step explanation:
Using x and y as the numbers
x+y=25 -------#1
x-y=9 -------#2
Using addition of #1 and #2
x+y+x-y= 25+9
2x+0y=34
2x=34
x=17
Using the value of x and plugging said value into #1 or #2, we can find y
x=17
x+y=25
17+y=25
y=8
OR
x-y=9
17-y=9
-y=-8
y=8
The numbers are 8 and 17
16 desserts 8+8+8+8+8= 40 so 2/5 of 40 is 16
Hope this help Have a great day.
