13. 3(x-6)-8=-2 (you have to plug in x-6 as x in the equation

3x-18-8=-2 (distribute 3)

3x-26=-2 (combine like terms)

3x=24 (subtract 26 to both sides)

x=8 (divide 3 to both sides)

14. -2(3(5y+5)=-4

-2(15y+5)=-4

-30y-10=-4

30y=6

y=1/5

15. (3x-5) +2x = 90

16. Let m be the number of minutes

0.75m+32 = 47

Using this equation you can find the number of minutes.

0.75m = 15 ( subtract 32 to both sides)

m= 20 (divide 0.75 to both sides)

Vera called 20 minutes beyond her allowed minutes.


Here I hope that this helped you out hon :)

Given : A metallurgist wants to study four different fluxes, two different base metals, and three different amounts of energy input.

i.e. 4 different choices for fluxes.

2 different choices for base metals.

3 different choices for amounts of energy input.

If each run of the experiment involves a choice of one flux, one base metal, and one amount of energy input.

Then , the number of runs are possible :-

A city has 20 radio stations including 5 college stations. What is the probablility that a randomly chosen radio station in this
densk [106]

Answer:

1/4

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

the probability that a randomly chosen radio station in this city is a college radio station = number of college stations / total number of city radio stations

= 5/20

To transform to the simplest form. divide both the numerator and the denominator by 5

= 1/4
