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.

<h2>
Answer:</h2>
<u>The mean altitude will be</u><u> -54 per minute</u>
<h2>
Step-by-step explanation:</h2>
We are given with altitude change as -378 feet over 7 minutes
Now
We need feet per minute
So -378 / 7 will give us the altitude change per minute
-378 / 7 = -54
Therefore the mean change of altitude in feet per minute is -54 per minute
Answer:
3.00
Step-by-step explanation:
Given that :
Payout(X) : ___ 0 ___ 4 ___ 6 ____ 8 _____ 10
Probability (p(x) 0.5 _ 0.2 __0.15 __0.1 ___ 0.05
Expected value :E(X) = ΣX* p(x)
E(X) = (0*0.5) + (4*0.2) + (6*0.15) + (8*0.1) + (10*0.05)
E(X) = 3
Expected value = 3.00
Hey there!
If he has 24 cattle that eat 12 pounds of grain every day, then the amount of grain that they eat every day can be represented by the following equation:
p = 24 x 12 Multiply the two together, and the amount eaten each day is 288 pounds.
We can divide 10656 by 288 to figure out how many times 288 will go into 10656, which tells us how many days the supply will last.
10656 ÷ 288 = 37
So this means the food supply will last 37 days.
Hope this helps!
We can use fraction to solve this problem. Since Jean can fill the pool in 8 hours and Mark in 12 hours, we can use the formula X/8 + X/12 = 1 where X/8 stands for Jean's job and X/12 for Mark's.
X - total number of hours Jean and Mark can fill the pool
To add the two fractions, we need to have the same denominator which is 24.
The equation will be (3X + 2x) / 24 = 1, which will give us a simplified formula of 5X / 24 = 1.
To get X, we need to multiply 24 to both sides (5X/24 and 1) so that the equation will be 5X = 24. We only need to solve for X, so we will remove 5 from X by dividing it to 24, giving us the equation 5X/5 = 24/5.
The final answer will be X = 24/5 hours or 4.8 hours.
Therefore, the supervisor is incorrect since Jean and Mark can fill the pool in less than 10 hours.
