Answer:
[tex](14 + 7) + 12 = 14 + (7 + 12)[/tex]
Step-by-step explanation:
Given
[tex](14 + 7) + 12[/tex] --- [Missing in question]
Required
Select equivalent expression
[tex](14 + 7) + 12[/tex]
Associative property states that:
[tex](a + b) + c = a + (b + c)[/tex]
In this case:
[tex]a = 14[/tex]
[tex]b = 7[/tex]
[tex]c = 12[/tex]
So, we have:
[tex](a + b) + c = a + (b + c)[/tex]
[tex](14 + 7) + 12 = 14 + (7 + 12)[/tex]
B. is correct
Calculate the average rate of change for the given function, from x = −3 to x = 7.
Answer:
The average rate of change for the given function, from x = −3 to x = 7 will be:
Average rate = -5Step-by-step explanation:
Given the table
x f(x)
-3 50
3 10
7 0
As the interval is from x = -3 to x = 7.
so
at x₁ = -3, f(x₁) = 50
at x₂ = 7, f(x₂) = 0
Using the formula to determine the average rate of change at which the total cost increases will be:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [0 - 50] / [7-(-3)]
= [-50] / [7+3]
= -50 / 10
= -5
Therefore, the average rate of change for the given function, from x = −3 to x = 7 will be:
Average rate = -5George is given two circles, circle O and circle X, as shown. If he wants to

Answer:
B the division one
Step-by-step explanation:
The solution is, : B.) The correct second step for the given proof is;
C/C' = 2πr/2πr' and, C/C' = r/r'
by the division property of equality.
What is division?Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
Explanation:
We want to find the correct second step for the given proof.
Recall that from division property of equality, when we have;
a=b and c=d, dividing the equations by each other, the equation will still be equal;
a/c = b/ d
For the given Prove;
statement 1 states that the circumference circle 1 and 2 can be expressed as;
C = 2πr and, C' = 2πr'
So, for step 2;
Applying the division property of equality, we have;
C/C' = 2πr/2πr'
which then equals,
C/C' = r/r'
Therefore, the correct second step for the given proof is;
C/C' = 2πr/2πr' and, C/C' = r/r'
by the division property of equality.

A bag contains 7 raspberry candies, 13 caramel candies, and 5
coffee candies. You are going to reach into the bag and pull out
some candies without looking. What is the least number of
candies that you must pull out to be sure that you have
removed at least three coffee candies?
if August 3rd wos four days after one
Answer:
15Step-by-step explanation:
There are total cadies in the bag:
7 + 13 + 5 = 25Probability of pulling a coffee candy is:
5/25 = 1/5So each 5th candy should be coffee candy
Then you need to pull at least:
5*3 = 15 candiesNote:
To ensure 3 coffee candies you would need to pull 25 - 2 = 23 candies

At the neighborhood grocery, 55 pounds of steak cost \$20.60$20.60. How much would it cost to buy 44 pounds of steak?
Answer:
$16.48
Step-by-step explanation:
Create a proportion where x is the cost of 44 pounds of steak:
[tex]\frac{55}{20.60}[/tex] = [tex]\frac{44}{x}[/tex]
Cross multiply and solve for x:
55x = 906.4
x = 16.48
So, the cost of 44 pounds of steak is $16.48
(a) Complete the table of values for the graph x + y = 6
Please help ❤️ complete the table leave the graph bit as I know how to do it
Answer:
(0,6)
(1,5)
(2,4)
(3,3)
(4,2)
Step-by-step explanation:
To solve this table first convert the equation to slope-intercept form (y=mx+b), to do this solve for y in the equation. The slope-intercept form is y=-x+6, where -1 is the slope and 6 is the y-intercept. Then from that, you can get your first point, because you know the y-intercept is 6, therefore when x equals 0 y must be 6. Next, because the slope is -1 that means the y-value decreases by 1 every time the x-value increases by 1. So to find the rest of the y-values simply subtract 1 from the previous y-value.

There are 4 groups
1. Alto
2. Bass
3. Tenor
4. Soprano
The question says "what is the probability that this member comes from the alto section"
Since there are 4 groups, I did 4/8 (since there are 8 people in Alto) and I got 0.5.
Hope I got it right and it helped you
*Note* I most likely got it right I just doubt myself too much lol
But just in case, I hope I got it right.
Answer:
there are 4 parts in that choir and the alto members are 8 in number so we say those in alto divided by the number of parts, we get→ 4÷8 =0.5, that's the ans.

15. Express 2/5 as a percentage
Answer:
[tex]40\%[/tex]
Step-by-step explanation:
[tex] \frac{2}{5} \times 100 = 40\%[/tex]
Divide 2 by 5 to get a decimal, then multiply the decimal by 100 to get a percent.
2/5 = 0.4
0.4x100 = 40
2/5 = 40%

2x-16+24 = 2x+8
2x = -8
x = -4
Hey there!
2(x - 8) + 2(12)
DISTRIBUTE 2 WITHIN PARENTHESES
= 2(x) + 2(-8) + 2(12)
= 2x - 16 + 24
COMBINE the LIKE TERMS
= 2x + (-16 + 24)
= 2x + 8
Therefore, your answer is: 2x + 8

The difference of five times a number and 6 totals 29
Step-by-step explanation:
Let x represent the number.
We have 5x - 6 = 29 or 6 - 5x = 29.
=> 5x = 35 or 5x = -23
=> x = 7 or x = -4.6.
The number can be 7 or -4.6.
We have 5x - 6 = 29 or 6 - 5x = 29.
=> 5x = 35 or 5x = -23
=> x = 7 or x = -4.6.
The number can be 7 or -4.6.

a1 = -70
d = -10
an = - 100
Formula
an = a1 + (n - 1)*d
Solution
-100 = -70 + (n - 1)*-10 Remove the brackets.
-100 = - 70 + -10n + 10 Combine
-100 = -60 - 10n Add 60 to both sides
-100+60 = -60+60 - 10n Combine
-40 = - 10n Divide by - 10
-40/-10 = n
n = 4

Answer:
He would drive 536 miles in 5 hours
Step-by-step explanation:
First set up your equation:
804 = 12x
Divide 804 by 12 and get 67 = x
Since per one hour you drive 67 miles, multiply 67 by 8 and get 536.
So, he drives 536 miles in 5 hours
Answer: I think 402
Step-by-step explanation: I divided 804 to 4 and I got 201 then I added 201+201= 402 and each 4 hours he went 201 miles so if you add 201 and 201 you get 402 miles. Hope it helped!! :)

· The list price of an article is 25% above the selling price and the cost
price is 40% below the list price. Find the rate of discount and profit?
Answer:
p=25%
discount=25%
Step-by-step explanation:
Cost Price = 1.25 x - .4(1.25x)= 1.25x- .5x
Cost Price = .75x
S P = C+P
Profit = Selling price - Cost price
= x - 0.75x
=0.25x
the Profit is 25 %
Discount is 25 %
