Valentin [98]3 years ago

Answer:

x = 4

Step-by-step explanation:

Sum of angles (in degrees) in a triangle = 180

so

60 + 70 + 12x + 2 = 180

Add like terms

132 + 12x = 180

subtract 132 from both sides

12x = 48

divide both sides by 12

x = 4

What is the simplified form of the equation 4/5n - 3/5 = 1/5n?
Oksi-84 [34.3K]

Answer:

n = 1 if you meant "(4/5)n - (3/5) = (1/5)n"

Step-by-step explanation:                                                                              

There's some ambiguity here.  Did you mean (4/5)n or did you

              4

mean --------- ?  Please use parentheses to eliminate this ambiguity.

              5n    

I'm going to assume that you meant to type in (4/5)n - (3/5) = (1/5)n.

Then we have (3/5)n = 3/5, or n = 1

The owner of a convenience store keeps track of how many customer buy lunch food during the "noon rush" each day for four days a
alexdok [17]

Answer:

c) 62.

Step-by-step explanation:

Let x represent number of customers came in on the fifth day.

We have been given that the mean number of customers for those four days is 52. So total number of customers on 4 days would be 4 times 52 that is 208 customers.

We know that mean of a data set is equal to sum of all data points divided by number of data points.

Total number of customers on 5 days would be 208+x and total number of days is 5.

Since we need a mean of 54, so we can set mean of 5 days equal to 54 as:

\frac{208+x}{5}=54

Multiply both sides by 5:

\frac{208+x}{5}*5=54*5

208+x=270

208-208+x=270-208

x=62

Therefore, 62 customers must come in on the fifth day to make the five-day mean 54 and option 'c' is the correct choice.
