Answer:

The Substitution Property of Equality allows you to say that if 7j + 14k = 28, and j = 2, then k = 1 .

Step-by-step explanation:

As the expression is given in the question be as follow .

7j + 14k = 28

As given the value of j = 2 .

Put the value of j in the equation 7j + 14k = 28 .

7 × 2 + 14k = 28

14 + 14k = 28

14k = 28 - 14

14k = 14

$k = \frac{14}{14}$

k = 1

Therefore the Substitution Property of Equality allows you to say that if 7j + 14k = 28, and j = 2, then k = 1 .

Is rolling doubles a simple event or compound event? Explain.<br><br><br> (rolling double dice)

nexus9112 [7]

You have to consider the sample space. In this example the sample space

is {1,2,3,4,5,6}

A simple event can be defined as a SINGLE outcome : Example getting a 3 OR 5 OR any other number from the sample space.

Now if you roll 1 dice & you want to get an even number (2,4,6) then you have chosen from the sample space 3 outcome & this is a compound event

Equally if you roll 2 dice and want to get "one" and/or "three" this is a compound event since you have chosen 2 outcome from the sample space.

Mind you, if you want 5 And 5 when rolling two dice it's a simple event because you have chosen ONE outcome from the sample space.

Hope this will help you to understand this kind of problem

<h3>What is Algebra?</h3>

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

Frances bought 144 shares of Dwyn horticulture for $7.73 apiece. her broker charged her a commission of $46.15 for the purchase.

Then the total amount spent by the company will be

→ 144 × $7.73 + $46.15 = $ 1159.27

If the yearly dividend on Dwyn horticulture is 61 cents per share, then the annual yield on Frances’s stock will be

$\Rightarrow \dfrac{0.61 \times 144}{11592.27} \\\\\Rightarrow 0.07577$
