Alright to solve this problem you must start by distributing the -1 to everything in the parenthesis. To distribute, multiply both the m variable and the 3 by a -1.
This simplification results in:
34 = -m - 3

Next, isolate your -m. To do this, add 3 on both sides of the equal sigh to keep everything balanced.
This gives you:
37 = -m

Since you want to find the value of m and not -m, flip the sign of the value in your answer by moving the negative parenthesis to the integer rather than the variable.
Like this: -(37) = m

Then, distribute the negative to your integer value.
Your simplified equation now looks like this:
-37 = m

This leaves your final answer value for m as a -37.

I hope this is correct and helpful to you! :)

Answer:

Sample response: The negative sign outside the parentheses represents –1. Distribute the –1 to everything inside the parenthesis. Use the addition property of equality first to add 3 to both sides. Then use the division property of equality to divide both sides by -1.

Step-by-step explanation:

I just completed the test. I hope this helps you :)

The half life of a certain tranquilizer in the bloodstream is 37 hours. How long will it take for the drug to decay to 86% of th
nata0808 [166]

Answer:

  8.1 hours

Step-by-step explanation:

A model of the fraction remaining can be ...

  f = (1/2)^(t/37) . . . . t in hours

So, for the fraction remaining being 86%, we can solve for t using ...

  0.86 = 0.5^(t/37)

  log(0.86) = (t/37)log(0.5)

  t = 37·log(0.86)/log(0.5) ≈ 8.0509 ≈ 8.1 . . . hours

It takes about 8.1 hours to decay to 86% of the original concentration.

Sara, Mark and Caroline share £102 in a ratio 1:3:2. How much money does each person get?
V125BC [204]

Answer:

Sara- 17

Mark- 51

Caroline- 34

Step-by-step explanation:

1) start by adding the ratios together, so 1+3+2= 6. Due to the order of the ratio, Sara, gets 1 art of the money, Mark gets 3 parts and Caroline get 2 parts.

2) take the total amount of money (102) and divide it by (1+3+2). 102/6 is 17.

3) divide the money by the amount each person gets. Sara only has one part, so she has £17, Mark gets 3 parts so he gets £51, and Caroline gets 2 parts, so she ends up with £34.

4) do 17+34+51 to check it equals 102. ( it does ;D)
