20 POINTS!! What would be the first step to solve this equation?
Anettt [7]

Answer:

C. Add 13 to both sides of the equation.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, m. Add 13 to both sides of the equation:

m - 13 = 24

m - 13 (+13) = 24 (+13)

m = 24 + 13

m = 37

The distance that light travels in 1 second is 186,000 miles. How far will light travel in 1 year? (There are approximately 31,5
Alchen [17]
Light travels 186,000 miles per second.....1.86 x 10^5
31,500,000 seconds per yr....3.15 x 10^7

how far will light travel in 1 yr...
(1.86 x 10^5)(3.15 x 10^7) =
(1.86 * 3.15)(10^5 * 10^7) =
5.859 x 10^12 miles in 1 yr <===
(5,859,000,000,000 miles)....whoa....a lot of traveling...thats like 5 trillion + miles

What do you do when the x is a negative but the answer for x is a positive?
Alecsey [184]
Just switch the negative sign over to the answer. so if you had -x = 6, then just switch the sign over to the 6. You would have the answer of x=-6, which is the same thing as -x=6

During an experiment, a spinner landed on green 9 times, which resulted in an experimental probability of StartFraction 1 over 6
ANTONII [103]

Answer:

Mary is incorrect

Step-by-step explanation:

We are given the following in the question:

Number of times the spinner landed on green color = 9

P(Green) =

\dfrac{1}{6}

Mary claimed that there must be 45 trials.

\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}

P(Green) =

\dfrac{\text{Number of times spinner landed on green}}{\text{Total number of trials}}\\\\\Rightarrow \dfrac{9}{x}=\dfrac{1}{6}\\\\\Rightarrow x  = 9\times 6 = 54

There are 54 trials in the experiment and not 45 trials. Thus, Mary is incorrect.
