tigry1 [53]

Answer:  Choice A) at most 2.5 ft wide

Work Shown:

16w ≤ 40

w ≤ 40/16

w ≤ 2.5

This says that the banner must be at most 2.5 ft wide (choice A)

In other words, the largest the width can get is w = 2.5; we can think of this as the ceiling value.

Answer:

10/11

Step-by-step explanation:

At first we have to swap the fractions to make those fractions into a normal number. Because it will become a multiplication.

4 × (x + 5) < 5 × (3x + 2)

We will multiply the numbers by the brackets.

4x + 20 < 15x + 10

Now we swap the constant and values from left to right side.

4x - 15x < 10 - 20

or, - 11x < -10

If we divide the inequality by a negative number, say - 11, the inequality becomes reverse.

Therefore,

[-11x ÷ (-11)] > [(-10) ÷ (-11)]

or, x > (10/11)
