Which equation demonstrates the distributive property? A = 7(1+6)=7(6+1) B = (7x1) x 6 = 7(1x6) C = (7x1) x 6 = 7(6x1) D = 7(1+6) = (7x1) + (7x6) HELP END OF SEMSSTER
Answer:
D. 7(1+6) = (7x1) + (7x6)Step-by-step explanation:
Let A, B and C be any integer or function. According to distributive property;
A(B+C) = AB + AC
From the expression, you can see that A is distributed over B and C during the expansion.
Based on this same concept, the equation that demonstrates the distributive property from the given options is 7(1+6) = (7x1) + (7x6)
From the equation, you can see that 7 is distributed over 1 and 6 to give 7(1) + 7(6).
The remaining options demonstrates the commutative property.

Answer:
-3 < 2x + 5 ≤ 7
Step-by-step explanation:
An inequality is a sentence with <, >, ≤, or ≥ as its verb. ... Similar statements hold for a ≤ b. ... To check, we can graph y1 = 3x - 5 and y2 = 6 - 2x. ... x ≤ 1. The solution set is {x|x ≤ 1}, or (-∞, 1]. The graph of the solution set is shown below. ... The sentence -3 < 2x + 5 ≤ 7 is an abbreviation for the preceding conjunction.

Answer:
$642
Step-by-step explanation:
To calculate sales tax, you multiply the percentage by the price. In this case it would be 600 x 0.07 which is 42. Then you add them together which would be 600 plus 42 which equals 642.
Find all values of x that make the equation true.
3/x-4 = x-5/x
The solution of the given equation are; X = -2 - 2√3 or x = -2 + 2 √3
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We have been given an equation as 3/x-4 = x-5/x
Therefore, 3/x-4 = x-5/x
3 - 4x /x = x² - 5 / x
Cancel out the denominator;
3 - 4x = x² - 5
x² - 5 - 3 + 4x = 0
x² - 8 + 4x = 0
x² + 4x - 8 = 0
For the value of x;
x = 4 + √16 + 32 / 2
x = -2 + 2√3
OR
x = 4 - √16 + 32 / 2
x = -2 - 2√3
Hence, The solution of the given equation are; X = -2 - 2√3 or x = -2 + 2 √3

Two kinds of tickets to an outdoor concert were sold: lawn tickets and seat tickets. Less than 400 tickets in total were sold. Lawn tickets cost $30 each and seat tickets cost $50 each. The organizers want to make at least $14,000 from ticket sales.
Write a system of inequalities to represent the situation. Be sure to define your variables.
Answer:
Tickets to sit on the bench (b) = 150
Tickets to sit on the lawn (l) = 200
Step-by-step explanation:
Tickets to sit on a bench (b)cost $75 each.
Tickets to sit on the lawn (l) cost $40 each
350 tickets had been sold
$19,250 had been raised through tickets sales
This forms a simultaneous equation:
b + l = 350 ... (i)
75b + 40l = 19,250 ... (ii)
Multiplying (i) by 40 and (ii) by 1 we get;
40b + 40l = 14,000 ... (i)
75b + 40l = 19,250 ... (ii)
Subtracting (ii) - (i) we get;
35b = 5250
b = 5250 ÷ 35 = 150

The Rodriguez family's ate 1/3 of a pan of brownies, they will take One part to their block party and the other to share with the co-workers. How much of the whole pan of brownies will each plate get?
Answer:
[tex]\dfrac{1}3[/tex]
Step-by-step explanation:
Given that:
Part of pan of brownies eaten by Rodriguez family = [tex]\frac{1}{3}[/tex]
One part of the remaining pan of brownies will be taken to the block party.
And the other part of the remaining pan of brownies will be given to the co-workers.
To find:
How much of the whole pan of brownies will be in each plate?
Solution:
First of all, let us find the remaining part of brownies after the family ate [tex]\frac{1}{3}[/tex] part of the pan.
Remaining = [tex]1-\frac{1}{3}=\frac{2}{3}[/tex]
Now, from the remaining pan of brownies, they are divided in 2 halves.
These part will be equal to:
[tex]\dfrac{\frac{2}{3}}{2} = \bold{\dfrac{1}{3}}[/tex]
Therefore, the answer is:
[tex]\dfrac{1}3[/tex]

5. What is the next term of the sequence -3, 6, -12, 24,... , and what it's arithmetic sequence?
Answer:
a(5)=-48
Step-by-step explanation:
I think u r confused
this sequence is geometric not arithmetic
HOw we know that ??
when we get a common difference that must Be equal
d=6+3=9 not equal to d=-12-6=-18
So it is not arithmetic
but when we get the common ratio that also must be equal
r=6/-3=-12/6=24/-12=-2 equal
So it is geometric
By using this equation:
a(n)=a*r^(n-1)
and we have a=-3 , r=-2
Then a(n)=-3*(-2)^(n-1)
To get the next term:
a(5)=-3*(-2)^(5-1)
a(5)=-3*(-2)^(4)
a(5)=-3*16=-48
