Well, basically what they are trying to do is isolate the y variable on the left side of the equation in order to get it in slope-intercept form (y=mx+b where "m" equals the slope and "b" is the y-intercept). So, in order to do this they have to do the inverse operations (so if it's adding they subtract, and if it's multiplying they divide.) Anyways, they do this with the intention of getting only the variable "y" on the left side of the equal sign. Once they did all that they got it in slope intercept form, and they know that the coefficient in front of the variable x is the slope.

Henry is up for retirement after 35 long years at his pharmacy. Before retiring, he would like to know how much he would receive
satela [25.4K]

To find how much Henry can expect to receive from Social Security on a monthly basis, we first need to find how much he cant expect to receive from social security per year.

We know form our problem that Henry averaged an annual salary of $45,620, so to find how much can Henry expect to receive from Social Security per year, we just need to find the 42% of $45,620.

To find the 42% of $45,620, we are going to convert 42% to a decimal by dividing it by 100%, and then we are going to multiply the resulting decimal by $45,620:

\frac{42}{100} =0.42

Social security annual payment = (0.42)($45,620) = $19,160.40

Since there are 12 month in a year, we just need to divided the social security annual payment by 12 to find how much he can expect to receive each month.

Social security monthly payment = \frac{19,160.40}{12} = $1.596.70

We can conclude that Henry can expect to receive $1.596.70 monthly from Social Security.

Suppose you have 28 coins that are all dimes and quarters. The total value of the coins is $5.35. Write a system of equations th
Inessa [10]

Answer:

1) The system of equations that models this situation is given as follows

0.1·x + 0.25·y = 5.35...(1)

x + y = 28...(2)

2) The number of dimes = 11 dimes

The number of quarters = 17 quarters

Step-by-step explanation:

1) The given parameters are;

The numbers of quarters and dimes = 28

The total value of the coins = $5.25

Let x represent the number of dimes and y represent the number of quarters, and given that a dime = $0.1 and a quarter = $0.25, we have;

The system of equations that models this situation is given as follows

$0.1·x + $0.25·y = $5.35...(1)

x + y = 28...(2)

2) Making y the subject of both equations gives;

From equation (1), we have;

0.1·x + 0.25·y = 5.35

0.25·y = 5.35 - 0.1·x

y = 5.35/0.25 - 0.1/0.25·x = 21.4 - 0.4·x

y = 21.4 - 0.4·x

From equation (2), we have;

x + y = 28

y = 28 - x

Equating both equations to find the common solution, gives;

21.4 - 0.4·x = 28 - x

x - 0.4·x = 28 - 21.4

0.6·x = 6.6

x = 6.6/0.6 = 11

x =  11

The number of dimes = x = 11

y = 28 - x = 28 - 11 = 17

y = 17

The number of quarters = y = 17.
