Answer: 5

Step-by-step explanation: To solve for <em>x</em> in this equation, we want to get <em>x</em> by itself on the left side of the equation.

Since <em>x</em> is being multiplied by 1.2, to get <em>x</em> by itself, we need to divide by 1.2 on the left side of the equation. Since we divided by 1.2 on the left side, we must also divide by 1.2 on the right side.

On the left side, notice that the 1.2's cancel out so we are simply left with <em>x</em>. On the right side, we have 6 ÷ 1.2 which is 5 so we have x = 5.

Finally, remember to check your answer by substituting a 5 back into the original equation.

So we have 1.2 (5) = 6 which is a true statement so our answer is correct.

Remember to show all your work when solving equations.

suppose that a severe virus in impacting a bee colony and the population of bees has a half life of 5 days What percentage of th
BartSMP [9]
So we want to know what percentage of bees would survive a virus after 19 days of decay if the bee population has a half life of 5 days. So every 5 days 50% of bees die. Lets say that N is the number of bees before the virus. So after 5 days is 50% less bees, so 50% of N remains. After another 5 days again, 50% bees die, and 50% out of 50% is 25%. So after 10 days, 25% of bees remain or 25%N or 0.25*N. After another 5 days its 12.5 % of bees remain or 0.125*N. And after 4 days 40% more bees die. And that is 0.4*0.125*N = 0.05N. 0.05*100% is 5%. So after 19 days, 5% of bees remain and 95% of bees is dead.

Which of the following constants can be added to x^2- 3x to form a perfect square trinomlal?
creativ13 [48]

Answer:

A 21/4

Step-by-step explanation:

When forming a perfect square trinomial you need to "complete the square".

All of the steps to completing the square when solving an equation:

1.  The leading coefficient must be 1.  

2.  Divide b by 2.

3.  Square (b/2)

4.  Add (b/2)^2 to both sides to keep the polynomial balanced.

5.  You can now write the perfect square trinomial and solve.

x^2 - 3x  

-3/2

(-3/2)^2 = 9/4 = 2 1/4
