Answers
number in a=6000-2000x where x=number of hours
number in b=2000-1000x
when will a=b
so set them equal to each other and solve
6000-2000x=2000-1000x
subtract 6000 from both sdies
-2000x=-4000-1000x
add 1000x to both sdies
-1000x=-4000
multiply -1
1000x=4000
divide by 1000
x=4
in 4 hours, they will be the same, but, their numbers will be negative, so there is actually no real life time when they will be the same observe
1 hour: a=4000, b=1000
2 hour a=2000 b=0
3 hour a=0 b=-1000
4 hour a=-2000 b-=-2000
but you can't have -2000 cells, you can only have 0 or more than 0
Final answer:
Strain A and Strain B will have the same number of cells after 2 hours.
Explanation:
To find out when the two strains of bacteria will have the same number of cells, we need to calculate the time it takes for each strain to reach the same cell count. Let's start with Strain A, which decreases at a rate of 2000 cells per hour. We can set up an equation:
6000 - 2000t = 2000
Solving for t, we find that it will take 2 hours for Strain A to reach the same cell count as Strain B. Therefore, the two strains will have the same number of cells after 2 hours.

Answer:
We know that numerical expressions are the expressions that contains numbers and operations namely addition, subtraction, multiplication and division.
Now, numbers are required in our life to make it easier.
For e.g. If we need to find the number of candies which are to be distributed among the class of 50 students, where each student get 2 candies each.
We do not start counting the numbers but instead use numerical expressions as,
Number of students in the class = 50
Number of candies each student gets = 2
Total number of candies required = 50 × 2 =100.
So, we see that in place of using the time consuming method of counting, we used numerical expressions which saved the time and was easy to apply.
In this way, there are numerous real-life situations which are easily solved with the help of numerical expressions such as when we need to find how much discount is applied to a product, to find the area of a rectangular park, to find the amount of ingredients required to bake a cake and many more.
The numerical expression is very helpful to solve the real world problem as they can be written in mathematical way and solved by algebraic operations.
What is numerical expression?
Number expression are the expression, which are used to represent the statement of general problem in the mathematical form. By this mathematical form the problem can be solved and real solution is find out.
The numerical expression are used to represent the general problem in the mathematical way to solve them.
The numerical expression find the value of unknown objects.
Steps to write down the simple numericalexpression-
- Identify all the factors of the expression..
- Find the expression which gives same results.
- Equate the similar expressions.
For example let a problem in which there is total Andrew has 10 toys. He gives 2 to his brother, 3 to his friend and got 5 toys form his mother.
To find how many toys Andrew remains, we can write this problem in the numerical expression as,
Thus, the Andrew has 10 toys left.
Hence, the numerical expression is very helpful to solve the real world problem as they can be written in mathematical way and solved by algebraic operations.

Answer:
m= -84
Step-by-step explanation:
Step 1- Multiply both sides by 7
42-m= 126
Step 2- Move constant to the right hand side and change its sign
-m= 126-42
Step 3- Subtract the numbers
-m= 84
Step 4- Change the signs on both sides of the equation
m= -84

Answer:
Stephanie is selling the video games at a cheaper rate
Step-by-step explanation:
To find out who is selling video games at a cheaper rate, we need to calculate the price per game for each person.
For John:
$105 / 3 games = $35 per game
For Stephanie:
$136 / 4 games = $34 per game
Stephanie is selling the video games at a cheaper rate of $34 per game compared to John's $35 per game.
