Will the sum of two linear expressions each with an x-term , always,sometimes,or never have an x-term ? Explain your reasoning

Licemer1 [7]

Sometimes it will, and sometimes it won't.

I reason as follows:

(21 + x) + (30 + 2x) = 51 + 3x has an 'x' term

(42 + x) + (30 - x) = 72 has no 'x' term.

To add 20.4 + 3.75 + 4.25, Crystal first added 3.75 and 4.25. Which property did Crystal use to add mentally?

evablogger [386]

Answer:

Associative Property of Addition

Step-by-step explanation:

From the list of given options, option A correctly answers the question and this is because

$a + b + c = a + (b + c)$ --- (1)

$a + b + c = (a + b) + c$ --- (2)

<em>The above illustrations only apply to Associative Property of Addition</em>

In Crystal's case:

$20.4 + 3.75 + 4.25 = 20.4 + (3.75 + 4.25)$

This can be compared to (1) above

Hence;

<em>Option A answers the question</em>

Chin canned a number of quart jars anf a number of pints jars of tomatoes from hid garden. A pint is 16 onces and a quart is 32

ryzh [129]

Answer:

The equation which models the scenario is: 16 p + 32 q = 1280

Step-by-step explanation:

The total number of pints packed = p

The total number of quarts packed = q

The weight of 1 pint jar of tomatoes = 16 oz

So, the total weight of p pints = p x ( Weight of 1 pint) = p x ( 16 oz) = 16 p

The weight of 1 quart jar of tomatoes = 32 oz

So, the total weight of q quarts = q x ( Weight of 1 quart) = q x ( 32 oz)

= 32 q

Now, the TOTAL WEIGHT of p pints and q quarts

= Total weight of { p pints + q quarts} = 16 p + 32 q

Also, chin canned a total of 1280 ounces.

⇒ TOTAL WEIGHT of p pints and q quarts = 1280 ounces

or, 16 p + 32 q = 1280 ounces

Hence, equation which models the scenario is: 16 p + 32 q = 1280
