Answer:

3\frac{3}{4}

Step-by-step explanation:

12\frac{5}{8} -8\frac{7}{8}

First, make it as an improper fraction.

\frac{101}{8} -\frac{71}{8}

Now simply subtract the fractions.

\frac{101-71}{8}

\frac{30}{8}

Then let us write it in it's simplest form.

For that, divide both sides by 2.

\frac{15}{4}

And now let us write it as a mixed number.

\frac{15}{4} ⇒ 3\frac{3}{4}

Hope this helps you :)

Let me know if you have any other questions :-)

How to factor a trinomial x^2+11x+19
Tresset [83]

Answer:

this trinomial is prime, and cannot be factored.

Step-by-step explanation:

when expanding the equation, you multiply the last term by the first term's coefficient, and then find two factors that multiply to that product, and sum to the middle coefficient.

1 * 19 = 19

there are no factors that will multiply to 19 and sum to 11. thus, this polynomial is prime.

What is another way to write the expression t. (14--5) ?
melomori [17]

Answer: Second option.

Step-by-step explanation:

It is important to remember the Distributive Property in order to solve this exercise.

The Distributive property states that:

a(b+c)=ab+ac\\\\\\a(b-c)=ab-ac

In this case you have the following expression provided in the exercise:

t(14-5)

Then, in order to write this expression in another way, you can apply the Distributive property. Multiply each number inside the parentheses by "t".

Applying this procedure, you get:

t(14-5)=(t14)-(t5)

Notice that this expression matches with the one shown in the the second option.

Answer:

They are only equal on day 0, both having 10 population.

Step-by-step explanation:

Given the bacteria on the counter is initially measured at 5 and doubles every 3 days we can generate the following geometric equation:

f(x)=10*2^{\frac{x}{3} }

Given the bacteria on the stove is measured at 10 and doubles every 4 days we can create another equation:

f(x)=10*2^{\frac{x}{4} }

To find how many days it will take for the bacteria population to equal the same lets set both equations equal to eachother:

10*2^{x/3}=10*2^{x/4}

Divide both sides by 10

2^{x/3}=2^{x/4}

Since both exponents have the same base we can set the exponents equal to eachother and solve for x:

\frac{x}{3}=\frac{x}{4}

Multiply both sides by 3 to isolate x on the left side

x=\frac{3x}{4}

Multiply both sides by 4 to remove fraction

4x=3x

Subtract 3x to isolate x on the left side

x=0

Plug x into one of our original equations

f(0)=10*2^{0/3}

Solve

f(0)=10
