HOw do I solve 2m/7+3m/14=1 step by step

1 answer:

5 0

To add 2m/7 and 3m/14 you must make sure that their denominators are the same. To do this you must rewrite 2m/7 as 4m/14. They are both equal.

4m/14 + 3m/14 = 1

Add like terms.
7m/14 = 1

Multiply by 14 on both sides.
7m = 14

Divide by 7 on both sides.
m = 2

m = 2

HELP!!!!!

frosja888 [35]

Answer:

I think it is 350(1.2)^t because you take the starting amount (350) and then multiple it by the growth rate (which is 20%, but when added to 100 and the put into a decimal is 1.2) raised by the number of hours (t).

I hope this helps.

Suppose that the speeds of cars travelling on California freeways are normally distributed with a mean of miles/hour. The highwa

Answer:

the standard deviation of the speeds of cars travelling on California freeways is 6.0 miles per hour

Step-by-step explanation:

The computation of the standard deviation of the speeds of cars is shown below;

The z score for the top 1% is 2.326

So,

= (75 - 61) ÷ standard deviation = 2.326

Standard deviation is

= 14 ÷ 2.326

= 6.0 miles per hour

Hence, the standard deviation of the speeds of cars travelling on California freeways is 6.0 miles per hour
