Formule una propiedad algebraica basica del sistema de numeros reales para justificar cada uno de los siguientes enunciados, donde Y y Z representan numeros reales. a) (y + 2)z+3=(yz+2z)+3 b) (4+7)y=y(4+7) C) (1+4)+3=4+(1+3)
Answer:

Step-by-step explanation:
.
The algebraic properties that can be applied in this case are: distributive property, commutative property, associative property.
What properties can we apply in this situation?a) Distributive Property: (y + 2)z + 3 = yz + 2z + 3. The distributive property establishes that multiplication is distributed over addition or subtraction, allowing us to simplify the original expression by adding the product of y and z to 2z and then adding 3.b) Commutative property: 4y + 7y = y(4 + 7). The Commutative Property of Multiplication states that the order of the factors does not affect the result. Here, 4y and 7y can be rearranged as y(4) and y(7) respectively, keeping the same result.c) Associative Property: (1 + 4) + 3 = 4 + (1 + 3). The Associative Property of Addition states that numbers can be grouped in different ways without changing the sum total. Both sides of the equation group the numbers the same way.Note: The question is in Spanish. Here is the question in English:
Formulate a basic algebraic property of the real number system to justify each of the following statements, where Y and Z represent real numbers. a) (y + 2)z + 3 = (yz + 2z) + 3
b) (4 + 7)y = y (4 + 7)
c) (1 + 4) + 3 = 4 + (1 + 3)

What is the solution to the system -3×+4y+2z=-3 2×-4y-z=0 y=3x-13
Answer:
x=5, y=2, z=2
Step-by-step explanation:
y=3x-13
-3x+4y+2z = -3x + 4(3x-13) + 2z = 9x+2z-52 = -3
9x + 2z = 49 ... (1)
2x-4y-z = 2x-4(3x-13)-z = -10x-z+52 = 0
10x + z = 52 ... (2)
(2)*2-(1): 11x = 55 x = 5
y = 3x-13 = 15-13 = 2 y=2
z = (49-9x) / 2 = 2 z = 2
toni had 5 1/2 kilograms of sugar.how many cakes can he bake if he ise 1/4 hilogram of sugar per cake?
pls i need the answer
Answer:
22 cakes
Step-by-step explanation:
5 1/2kg = 11/2 = 22/4
22/4 is what you have in sugar while you only need 1/4 per cake, so you can make 22 cakes
Answer:
He can makec 22 cakes
Step-by-step explanation:
He use,
[tex] \frac{1}{4} kg = 1 \: \: cake \\ [/tex]
Let's find how many caked will he make from 5 1/2kg
Let the unknown number of cakes be x
[tex] \frac{1}{4} = 1 \\ 5 \frac{1}{2} = x[/tex]
[tex] \frac{1x}{4} = 5 \frac{1}{2} \\ \frac{1}{4} x = \frac{11}{2} [/tex]
Use cross multiplication
[tex]2 \times 1x = 11 \times 4 \\ 2 x= 44 \\ \frac{2x}{2} = \frac{44}{2} \\ x = 22[/tex]

You can use the method of calculating the percentage of an amount to find out the discount amount.
The discount price for the given condition was $205.2
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is [tex]\dfrac{a}{100} \times b[/tex]
How to find the discount price?First we will find the marked price since the discount price was calculated on the marked price.
Since marked price was 150% of the cost price $456, thus,
[tex]\text{Marked price} = \dfrac{456}{100} \times 150 = \$684[/tex]
Thus, the marked price of the furniture was $684
Now, since the discount offered on the price was 30%, thus,
[tex]Discount = \dfrac{\text{Marked price}}{100} \times \text{Discount percent} =\dfrac{684}{100} \times 30\\\\Discount = \$205.2[/tex]
Thus,
The discount price for the given condition was $205.2

Is (3,-10) a solution to the function y = - 4x + 2? Answer "yes" or "no". Then explain why it is or
is not a solution
Need ASAP
Answer:
Yes
Step-by-step explanation:
( x, y ) = ( 3, - 10 )
Here,
x = 3
y = - 10
y = - 4x + 2
- 10 = - 4 ( 3 ) + 2
- 10 = - 12 + 2
- 10 = - 10
LHS = RHS
Therefore,
( 3, - 10 ) a solution to the function y = - 4x + 2.
