Based on the task content; If you multiply both sides of an inequality by a negative number, the inequality symbol should be reversed always. Option B
<h3>Multiplication of inequality</h3>
Based on the rule of inequality, whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign.
For instance,
-4x > 12
divide both sides by -4
x < 12/-4
x < -3
If you multiply both sides of an inequality by a negative number, the inequality symbol should be reversed always.

Answer:
There are 21 blue marbles
Step-by-step explanation:
In this question, we are asked to calculate the number of blue marbles in a bag that contains a total of 60 marbles, given the probability of choosing a blue marble.
Mathematically, the probability of choosing a blue marble can be represented as:
P(B) = number of blue marbles/ Total number of marbles
From the question, we can identify that P(B) is 0.35, number of Marbles is unknown while the total number of marbles is 60.
We insert these values in the equation;
0.35 = number of blue marbles/60
Hence, number of blue marbles = 60 * 0.35 = 21
ummm -4.5 since you just observe this is negative
The answer is 1 2/7b.
1/3b multiplied by itself 3 times is 1 2/7b.
Scientific notation is written as
(number<u>></u>1 and <10) times (10^x) so
count how many decimal places must be moved for the number to be <u>></u>1 and <10
the number must be 1.0 or 4 decimal places
put that in the x
but it makes the number bigger so make x negative
1 times 10^-4 is the scientific notation
