The variable in the equation 26 = 1 – 3r is r. Remembering the form ax + b = c, what are the values of the constants, a, b, and c in the equation?

Answers

The value of the constant a, b and c in the equation are -3, 1 and 26 respectively.

What is variable?

Variable are numbers represented by letters in a mathematical equation. Therefore,

26 = 1 - 3r

Using the form ax + b = c, where a, b and c are constant.  

The value of a, b and c in the expression 26 = 1 - 3r can be solve as follows:

-3r + 1 = 26

Melanie can run around the track 9 times in 28 minutes. At this rate, how many laps can she run in 1 hour and 15 minutes?

Answers

Step-by-step explanation:

First step is to identify what the problem is asking for and what is given.

9 laps in 28 minutes

Searching for number of laps in 1 hour and 15 min.

1 hour + 15 min. = 75 minutes convert to minutes

9 laps / 28 minutes = x laps / 75 minutes create an equation

9/28 = x/75

9*75 = 28x cross multiply

675 = 28x

x = 675/28 = 24.12 simplify

Melanie can run 24 complete laps in 1 hour and 15 minutes.

Brayden is working two summer jobs, making $21 per hour tutoring and making $10 per hour landscaping. In a given week, he can work a maximum of 12 total hours and must earn no less than $170. If xx represents the number of hours tutoring and yy represents the number of hours landscaping, write and solve a system of inequalities graphically and determine one possible solution.

Answers

Answer:

2 hours.

Step-by-step explanation:

Money earned for 14 hours of life-guarding = 14*18 = $252.  If he worked another 5 hours  to make the maximum of 19 he would earn 252 + 5*9

= $297  but he wants to work a minimum of hours for  a minimum of 270.

Thus we have the inequality:

252 + 9x ≤ 270

9x  ≤  18

x  ≤ 2.

So the number of hours he must do clearing tables = 2.

Answer:

The set of two or more inequalities in one or more variables is referred to as a system of inequalities, and the further discussion can be defined as follows:

System of inequalities:

Get y alone on one side of a linear inequality with 2 variables (x,y). Consider the equation that results when the inequality sign is changed to an equality sign. This equation has a line as its graph. A dashed line is drawn if the inequality is strict.

From the question, we know

[tex]21 x+10y \geq 170[/tex]  money

[tex]x+y \leq 12[/tex]           hours

so

Inequality [tex]1 : y\geq - \frac{21}{10} x+17\\\\[/tex]

Inequality [tex]2 : y\leq -x+12\\\\[/tex]

and [tex]x=0, y= 0[/tex]

For example

[tex]y = 2 \ \ \ x=10[/tex]
