Question

If x=15, y=19 and z=25, then

1. x+9+y-z
2. x * y * z
3. x+y+z/5

Please, I need it

Answer 1

1. x + 9 + y - z = 18

2. x * y * z = 7125

3. x + y + z/5 = 39

Explanation:

Given values:

x = 15

y = 19

z = 25

Let's substitute the values of x, y, and z into the given expressions:

1. x + 9 + y - z

= 15 + 9 + 19 - 25

= 18

`\hrulefill`

2. x * y * z

= 15 * 19 * 25

= 7125

`\hrulefill`

3. If question is:
`\sf (x + y + z)/(5)`

`\sf = (15 + 19 + 25)/(5)`

`\sf = (59)/(5)`

= 11.8

`\hrulefill`

If question is:

`\sf x + y + (z)/(5)`

`\sf = 15 + 19 + (25)/(5)`

= 15 + 19 + 5

= 39
