The absolute value notation will be |x - 12| = 6
What is an absolute function?The absolute function is also known as the mode function. The value of the absolute function is always positive.
The absolute function is given as
f(x) = | x |
All numbers x is at a distance of 6 from the number 12. Then the equation will be
|x - 12| = 6
Simplify the equation, then we have
For x ≥ 0, then the value of x will be
x - 12 = 6
x = 18
For x < 0, then the value of x will be
- x + 12 = 6
x = 6
The absolute value notation will be |x - 12| = 6

A "size 7" shoe is about 1.4 x 10-¹ meters long. The circumference of the earth is about meters 1.06 x 10^7 around the equator. How many shoes, end-to-end, would it take to wrap around the equator? Show how you expanded and used the Giant One.
Answers
Number of shoes needed to wrap around the equator = 7.57 x10⁷
The length of a size 7 shoe = 1.4 x 10-¹ m
The circumference of the Earth around the equator = 1.06 x 10^7 m
We know that here, the circumference around the equator will be equal to the number of shoes times the length of each shoe.
So to find the number of shoes, we should divide the circumference of the Earth by the length of one shoe.
Hence, number of shoes end-to-end needed to wrap around the equator = 1.06 x 10⁷ / 1.4 x 10-¹
= 7.57 x10⁷

7) (x, TU, TB) = (4, 8, 13)
9) (x, RS, MN) = (8, 41, 41)
11) (AB, BC, AC) = (42, 42, 84)
What are the values of the variable x and the lengths of the line segments?
In this question we have three cases of colinear line segments, each of them can be solved by using definitions from Euclidean geometry and algebraic handling:
Case 7 - TU = 2 · x, UB = 3 · x + 1, TB = 21
TB = TU + UB
21 = 2 · x + 3 · x + 1
21 = 5 · x + 1
5 · x = 20
x = 4
Then, the lengths of each line segment are:
TB = 21
TU = 2 · 4
TU = 8
UB = 3 · 4 + 1
UB = 13
The solutions are (x, TU, TB) = (4, 8, 13).
Case 9 - RS = 3 · x + 17, MN = 7 · x - 15
RS = MN
3 · x + 17 = 7 · x - 15
4 · x = 32
x = 8
And the lengths of each line segment are:
RS = MN = 41
The solutions are (x, RS, MN) = (8, 41, 41).
Case 11 - AB = 2 · x - 8, BC = x + 17
AB + BC = AC
AB = BC
2 · x - 8 = x + 17
x = 25
And the lengths of each line segment are:
AB = 2 · 25 - 8
AB = 42
BC = AB
BC = 42
AC = 42 + 42
AC = 84
The solutions are (AB, BC, AC) = (42, 42, 84).

Rory has 3 pounds of ground turkey to make meatballs.He uses 3/8 pound per to make 6 meatballs. How many 1/8 pound meatballs can Rory make with the remaining turkey?
Answers
He can make 2 meat balls from the remaining turkey.
Total pounds of ground turkey available = 3 pounds.
Turkey used to make 6 meat ball = 3 / 8 of 3 pounds = 9 / 8 pounds
Turkey used to make 1 meat ball = 9 / 8 ÷ 6 = 3 / 16
1 / 8 meat = 1/ 8 of 3 = 3 / 8 pound of meat.
Number of meatballs made = 3 / 8 × 16 / 3 = 2
Therefore, he can make 2 meat balls from the remaining turkey.

The term 13(p+4) represents the (select)
The expression 27p +13(p+4) represents the (select)
Answers
Answer:
The term 27p represents the total cost in dollars of pants
The term 13(p+4) represents the total cost in dollars of shirts
The expression 27p+13(p+4) represents the overall cost in dollars of the shirts and pants Christ buys
Step-by-step explanation:
Disclaimer: if the owner can include the options, I can give a better answer.
We know each pair of pants is $27. Since each pair of pants costs $27, we can say the total cost in dollars of pants is equal to 27*P. For each pair of pants Chris buys, he buys 4 shirts. P+4 is the total number of shirts Chris will buy. The price of these shirts in dollars is $13. So we can assume the total cost in dollars of shirts will be 13(P+4). The total expression is the total amount in dollars Chris spends.
Find the area of the region enclosed by the curves y = 7 sin x and y = sin(7x) , 0 < x
Answers
The area of the region enclosed by the curves y = 7sin x and y = sin(7x) , 0 < x < π is 13.7 square units.
Given the equation of the curves:
y = 7sin x and y = sin(7x)
Now, we have to find the area between the curves .
Area between y = 7sin x and y = sin(7x) ,
A = ∫[7sin(x) - sin(7x)]dx
⇒ A = [-7cos(x) + 1/7 cos(7x)]
⇒ A = [-7cos + 1/7 cos(7)] - [-7cos(0) + 1/7 cos(0)]
Since cos(π) = -1 ; cos(7) = -1 ; cos(0) = 1
⇒A = [-7(-1) + 1/7 * (-1)] - [-7 * 1 + 1/7 * 1]
⇒A = 7- 1/7 + 7 - 1/7
⇒A = 14 - 2/7
⇒A = 96/7
