Let Pencils be P

Let notebooks be N

Let graph paper be G

Let cost be C

(Always write a let statement before you write and algebraic equation)

Answer:

C = 0.25x +1.75y +0.05z in dollars

Step-by-step explanation:

Let 'x' be the number of pencils, 'y' be the number of notebooks, and 'z' be the  number of graph papers bought. Then the total cost 'C' in dollars should be:

C = 0.25x +1.75y +0.05z

What is 72.1 repeating as a fraction? Simplified.
Viefleur [7K]
The answer is quite simple after looking at it. 0.1 is a tenth. 72 is a whole number, so you would have 72 1/10.   1/10 is a tenth and 72 is still the whole number.

The maths question for algebra is
ankoles [38]

Step-by-step explanation:

Let (2n +1) be the larger odd number by definition, where n can be any real integer. Then (2n - 1) is the smaller consecutive odd number.

The product of the 2 odd numbers is (2n + 1)(2n - 1) = 4n^2 - 1 = 2(2n^2) - 1. Since n^2 must be an integer, 2(2n^2) - 1 is odd. (Shown)

                                                        Solutions 

                          g(x) = \frac{1}{3} - \frac{4}{3} x 

                          g(x) = - <span>\frac{4}{3} x + \frac{1}{3} 

                           x = -5 

                           = </span>g(x) = - \frac{4}{3} × (-5) + <span>\frac{1}{3} 
</span>
                           = \frac{20}{3} + <span>\frac{1}{3} 
</span>
                           = \frac{21}{3} 

                           = 7 

(-5,7)
