Step-by-step explanation:
-2x+3x=-21+6
or x=-15
Answer:
x=3
Step-by-step explanation:
-2x-6=3x-21
Add 21 to both sides of the equation
-2x-6+21=3x-21+21-2x+15=3xAdd 2x to both sides of the equation
-2x+2x+15=3x+2x15=5xDivide each side by 5 to isolate x

a train travels 16 miles in 20 minutes how many minutes would 12 miles be
Answer:Then 16x = 240, and x = 240/16 = 15. It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
16 miles = 12 miles
20 mins. how many mins?
16 = 12 cross multiply 16? = 240 divide by 16 240 divided by 16 = 15 miles
20 ? because 15 x 16 = 240
Answer:
It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
Write and solve an equation of ratios:
16 miles 20 min
----------- = -----------
12 miles x
Then 16x = 240, and x = 240/16 = 15.

Step-by-step explanation:
If amount of utility bill is normally distributed with a mean of $105 and a standard deviation of $20. What percentage of your bills would you expect to be between $85 and $125?
Answer:
68% of your bills between $85 and $125
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = $105
Standard deviation = $20
What percentage of your bills would you expect to be between $85 and $125?
85 = 105 - 20
125 = 105 + 20
Within one standard deviation of the mean, so by the Empirical Rule, 68% of your bills between $85 and $125

Answer:
C) 1/3, 2, √7
Step-by-step explanation:
√7= 2.6
1/3= 0.3
2=2
1/3, 2, √7
C.
*if using a calculator*
1/3= .333
square root 7 equals about 2.646
therefore, we know .333 (1/3) is the smallest out of the numbers and 2.646 (sqr root 7) is the biggest.
*if you cannot use a calculator*
We know 1/3 is less than 1 because 3/3 would equal 1 and we only have 1/3.
We don’t know the square root of 7, however we know that it has to be between 2 and 3 because the square root of 4 is 2 and the square root of 9 is 3. 7 is between those two numbers, so therefore we know that the square root would have to be between 2 and 3.
Knowing that, we could figure out that since 1/3 is less than 1 it would be the smallest. Since the sqr root of 7 is between 2 and 3, it would be bigger than 2 and the biggest out of the 3.
Conclusion:
The order is 1/3, 2, sqr root 7

Explain how you change a decimal to a fraction.
Answer:
Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.
