Find the sum of - 3x^2 + 5x – 8 and -10x^2 – X – 3.
Answers
The sum of - and
is:
To find the sum of and
you simply add the like terms together.
Like terms are terms that have the same variable and the same exponent.
Now, add the like terms:
5x + (-x) = 4x
-8 + (-3) = -11

Answer:
-13x^2+4x-11
Step-by-step explanation:
-3x^2+5x-8+(-10x^2-x-3)=?
-3x^2+5x-8-10x^2-x-3=?
(combine like terms); -13x^2+4x-11
So, your answer is -13x^2+4x-11

Final answer:
It would take approximately 30 days for a single-cell amoeba to produce a population of about 10,000 amoebae.
Explanation:
To find out how long it would take for a single-cell amoeba to produce a population of about 10,000 amoebae, we need to calculate the number of times the amoeba doubles. Since the amoeba doubles every 3 days, we can find out the number of doubling periods it would take to reach 10,000 amoebae by dividing 10,000 by 2. This equals approximately 9.965, which means the amoeba would need to double about 9.965 times. Since we can't have a fraction of a doubling period, we can round it up to 10.
Each doubling period is 3 days, so to find out how long it would take, we can multiply the number of doubling periods (10) by the time interval for each doubling period (3 days). 10 x 3 = 30. Therefore, it would take approximately 30 days for a single-cell amoeba to produce a population of about 10,000 amoebae.

The total amount each employee contributes to buy the gift is given by the equation A = $ 0.73
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the amount contributed by each employee be A
Now , the total amount for the gift = $ 16.06
The total number of employees = 22 employees
So , amount contributed by each employee A = total amount for the gift / total number of employees
On simplifying the equation , we get
The amount contributed by each employee A = 16.06 / 22
The amount contributed by each employee A = $ 0.73
Hence , the amount contributed by each employee is $ 0.73

- Two cupcakes require 2/3 of a cup of icing.
- This means that one cupcake requires (2/3) / 2 = 1/3 cup of icing.
Now, you can calculate how many cupcakes can be frosted with one cup of icing:
Number of cupcakes frosted = (1 cup of icing) / (1/3 cup of icing per cupcake)
Number of cupcakes frosted = (1 cup) / (1/3 cup) = 3 cupcakes
So, with one cup of icing, you would be able to frost 3 cupcakes.
