Answer:
x<7
Step-by-step explanation:
Divide by -7 on both sides and when dividing by a negative you should flip the inequality sign.
Answer:
The solution set would be all real numbers
Step-by-step explanation:
Remember that you should pass from one side to the other the terms which are similar, that is to say x with x and numbers with numbers. In doing so you must be sure to change the sign of the term if it is passed from one side to the other.
In this case it would be:
4x + 7x + 1 < 11x + 2
(Four plus seven is 11)
11x + 1 < 11x + 2
We can see that x is eliminated, because we change the sign on 11 to be -11:
11x - 11x + 1 < 2
1 < 2
This result means that no matter which value we give to x, the inequality will be always true. For that reason the answer is all real numbers
Answer:
False
Step-by-step explanation:
numbers are integers, the integers are negative, zero and positive,
while natural numbers are only positive,
therefore the statement is false
. False. Integers comprise negative and positive numbers (...- 3, -2, -1, 0, 1, 2, 3 ...) and natural numbers only comprise positive integers (0, 1, 2, 3 ...)
Answer:
Let x be the number;
We solve the equation x ÷ 4 - 5 = 15;
Then x ÷ 4 = 20;
Finally x = 80;
