Answer:

The associative property will be:

(14\textbf{.}\frac{1}{7})\frac{2}{5}

So, Option C is the correct option.

Step-by-step explanation:

We need to write the expression that uses the associative property to make it easier to evaluate: 14(\frac{1}{7}\textbf{.}\frac{2}{5}  )

The associative property of multiplication states that: a(b\textbf{.}c)=(a\textbf{.}b)c

So, For the given expression:

14(\frac{1}{7}\textbf{.}\frac{2}{5}  )

The associative property will be:

(14\textbf{.}\frac{1}{7})\frac{2}{5}

So, Option C is the correct option.

Find the output of the function y = x - 16 if the input is -28.<br> Help please
Serhud [2]

Answer:

-44

Step-by-step explanation:

If the input is -28, that means x = -28, so we plug -28 in for x and solve for y, which is the output:

y = x - 16

y = -28 - 16 = -44

The answer is thus -44.

A hardware store clerk mixed nuts worth $1.32 per kilogram with bolts worth $1.20 per kilogram. If he made 108 kilograms of a mi
AlladinOne [14]

Answer:

the way to work these types of problems is to create a table. The table will have three rows and three columns.

The table:

Let x represent the kilograms of nuts, then 138 - x will represent the kilograms of bolts.

Product     Amount        Cost            Total

--------------------------------------------------------

  Nuts          x               .60         .60 * x

  Bolts      138 - x          .66         .66 * (138 - x)

  Mix          138             .65         .65 * (138)

Step-by-step explanation:

The equation:

The nuts plus the bolts must equal the mix or:

.60 * x + .66 * (138 - x) = .65 * 138

I do not like to work with decimals, so multiply each term by 100:

60 * x + 66 * (138 - x) = 65 * 138

Remove the parenthesis and combine like terms:

-6x = -66 * 138 + 65 * 138

-6x = -138

Divide both sides by -6:

x = 23

Solution:

The mixture contains 23 kilograms of nuts.

The mixture contains 138 - 23, or 115 kilograms of bolts.
