Consider this option:
1. rule: the equation will be the same if the both its parts are multiplied by one number ('0' is not included!).
2. using the rule, described upon:
-3x-2y=-7 (*(-1));
6x+4y=14 (*2);
-6x-4y=-14 (*(-2)).

Note, that not all the ways are described.

Rita and Tina each make $11 an hour working as cashiers at a supermarket. Last week, Rita worked r hours while Tina worked t hou
Hoochie [10]

Answer: Rita and Tina's total weekly wages can be represented as  11r + 32 + 11t or 11( r + t ) + 32

Step-by-step explanation:

Since, For Rita,

Charges per hour =  $ 11

Working time = r hours,

Overtime charges for a week = $ 32,

Thus, her weekly charges = 11 r + 32

Now, For Tina,

Charges per hour  = $ 11

Working time = t hours,

Thus, her weekly charges = 11 t

Hence, the combined weekly wages of both Rita and Tina = 11 r + 32 + 11 t

= 11( r + t ) + 32

Which is the required expression.

Which answers are examples of deductive reasoning?
Mariulka [41]

Answer:

The fair charges $5 for admission. Tom is going to the fair today. Therefore, Tom will spend $5 for admission to the fair today.

The radius of a circle is one-half the length of the diameter of a circle. The diameter of a circle is 10 ft. Therefore, the radius of the circle is 5 ft.

Step-by-step explanation:

Deductive reasoning or deduction, is one of the two basic types of logical inferences. A logical inference is a connection from a first statement to a second statement for which the rules of logic show that if the first statement is true, the second statement should be true. Basically one logical statement defines the base of the argument to reach the conclusion.

Here we can see that in first case:

The fair charges $5 for admission, so we know the fact that it charges $5 for the admission, now whoever goes to the fair will have to spend $5 to get in. Tom is going to the fair so Tom will spend$5 for admission to the fair. Therefore, this statement is deductive reasoning.

Case 2:

The radius of a circle is one-half the length of the diameter, this sentence is a fact. Now the diameter of a circle is 10ft so it is obvious that based on the previous sentence we will calculate the radius of the circle that is half of the diameter.

So only these two examples are based on deductive reasoning.
