1.If a number a is always less than another number b, which of the following expressions expresses their relationship? A. a≤b

B. a≥b

C. a>b

D. a 0

D. x 9
Which of the following sentences is the word equivalent of the expression above?

A. The product between 3 and a number is no less than 9.

B. The product between 3 and a number is greater than 9.

C. The product between 3 and a number is no more than 9.

D. The product between 3 and a number is less than 9.

Let's define the symbols:

x <  y

means that x is strictly less than y.

x ≤ y

means that x is less than or equal to y.

(both of these signs can be in the other direction, take that in mind).

A) " a is always less than another number b"

Here we should have:

a < b.

a is always less than the other number b.

This is not in the options, so i suppose that there is a mistake in the question.

B) The expression "above" is not shown here, so i will just writhe the correspondent expression for each option, and you can see which one matches with the expression above.

a) "The product between 3 and a number is no less than 9"

3*n ≥ 9.

b) "The product between 3 and a number is greater than 9."

3*n > 9

c) "The product between 3 and a number is no more than 9"

3*n ≤ 9

d) "The product between 3 and a number is less than 9"

3*n < 9

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
