Tell whether the given value is a solution of the inequality.<br> x + 1 &gt; 10; x = 9
Oliga [24]

Answer:

given x+1 > 10,

x > 10 - 1

x > 9

which means x MUST BE more than 9 , which also means 9 isnt included in the inequality therefore x = 9 is not a solution.

Please help with question 6, 7, 8, and 9 about rational and irrational numbers
aliina [53]
6. When we multiply two surdic integers, we can leave it into one big surd.
For instance, if we have:

\sqrt{a} \cdot \sqrt{b}, we can simplify it down to one uniform square root sign, \sqrt{ab}.

So, we can say: 3\sqrt{2} \cdot 8\sqrt{18} = 24\sqrt{36}, which is a rational root, because the square root of 36 can be converted into an integer, namely 6 and -6.

Hence, it is a rational root.

7. The summation, on the other hand, cannot be simplified any further, so it will stay as irrational. This is because √2 is already an irrational root, and adding it onto a number that is rational will stay as irrational.

8. Once again, the summation cannot be simplified. We can only simplify by factoring like terms. Hence, this must be irrational.

9. Even if it is in fractional notation, √5 can never be a rational number because no two integers when multiplied by itself will give 5. So, even if it is written in fractional form, they cannot be rational if there is an already irrational term in it.

How to scientific notation to express the number 480 into 1 scientific notaion?
AfilCa [17]

Consider the number 480 in expanded form:

... 480 = 4×100 + 8×10

The left-most digit and multiplier are those that correspond to the ones you use in scientific notation.. You recall that 100 = 10×10 = 10². All this means is that

... 480 = 4.8×10²

10. The lengths of the electrical extension cords in a workshop are 6 ft, 8 ft, 25 ft, 8 ft, 12 ft, 50 ft, and 25 ft. What are t
Setler79 [48]
First, let's find the mode since It's the one with the different options among the answer choices. So the numbers that repeat are 8 and 25, so in order to find the in inches, you'd have to multiply that by 12.
8 x 12 = 96
25 x 12 = 300
Therefore, your answer is A.

A bag contains two steel balls and five brass balls. The total weight of the bag is 13 pounds. If two steel balls are added and
nlexa [21]

x = the weight of one steel ball y = the weight of one brass ball 2x + 5y = 13 (2 + 2)x + (5 - 2)y = 12 by solving the above system of equations we find:

x = 1.5 lbs y =2 lbs one steel ball weighs 1.5 lbs.one brass ball weighs 2 lbs.
