At a hardware store a bag holds up to 1 pound of nails. each penny nail (x) weighs 0.05 pounds and each wood nail (y) weighs 0.1 pounds. which inequality shows the solution for all combinations of the two kinds of nails that will fit in the 1-pound bag?

0.05x + 0.10y ≤ 1

Step-by-step explanation:

At a hardware store a bag holds upto 1 pounds of nails.

Each peny nails (x) weigh 0.05 pounds.

and wood nail (y) weigh 0.10 pounds

So total weight of penny nails and wood nails

= (0.05x + 0.10y)

This weight should be less than 1 pound bag.

So inequality formed will be 0.05x + 0.10y ≤ 1

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
