No. If 4x= 24 then x=6. 7 multiplied by 6 equals 42, not 35 so this is not a ratio.

The expression c+0.07c or 1.07c can be used to calculate the price including tax.
Step-by-step explanation:
Given,
Cost of jacket = c
Sales tax = 7%
Amount of sales tax = 7% of cost of jacket
Amount of sales tax =
Amount of sales tax = 0.07c
Cost of jacket including tax = Cost of jacket + Amount of sales tax
Cost of jacket including tax = c + 0.07c = 1.07c
The expression c+0.07c or 1.07c can be used to calculate the price including tax.

The set A satisfying the given inequality is A = (-, -10].
<h3>What are some properties of an inequality relation? </h3>
Following are some facts which are true for an inequality relation:
- Equal numbers can be added or subtracted from both sides of an inequality without affecting the inequality sign.
- The Inequality sign is unchanged if both sides are multiplied or divided by a positive number, but when multiplied or divided by a negative number the inequality sign is reversed.
Since y ∈ B, -2 ≤ y ≤ 7. So,
The set {-x | inequality (1) holds ∀ y ∈ B} is [10, ) i.e.
10 ≤ -x ≤ .
Multiplying -1 throughout gives
-10 ≥ x ≥ -.
x, thus, lies in the range A = (-, -10}.
