-1 1/9
Step-by-step explanation:
2x + 7x = -10 (equation)

Answer:
The smallest value of the three numbers would be 9.
Step-by-step explanation:
In order to find this, set the smallest number as x. Then you can set each of the next integers as x + 1 and x + 2. Now we can total all three numbers and set equal to 30 to solve for x.
x + x + 1 + x + 2 = 30
3x + 3 = 30
3x = 27
x = 9
Answer:
$121.5
Step-by-step explanation:
Given data
costs of phone = $150
discount= 25%
tax= 6%
amount of discount
= 25/100*150
=0.25*150
=$37.5
amount of tax
= 6/100*150
=0.06*150
=$9
amount payable
=150-37.5+9
=$121.5
Hence he will pay $121.5
