Sugar: x pounds
flour: 2x + 5 pounds
2x + 3(2x + 5) = 40
2x + 6x + 15 = 40
8x = 25
x = 3.125
-> a sack of flour is 3.125 + 5 = 8.125 pounds
I hope it‘s coorect
<span>-10 < x - 9

-1<x, or
x> - 1</span>
Answer:
x < 3
Step-by-step explanation:
Solve it like a normal equation
Isolate the variable along with its constant
9x - 6 + 6< 21 + 6
9x < 27
Isolate the variable its self
9x/9 < 27/9
x < 3
