Answer:
(B)-16+40
Step-by-step explanation: -8(2x-5)
-8*2=-16
-8*-5=40(positive because a negative multiplied by a negative is postive)
add the x to the answers...Then its -16x+40

A group of seven golfers paid $345 to play a round of golf. Of the golfers, one is a member of the club and six are nonmembers. Another group of golfers consists of two members and two
nonmembers. They paid a total of $140. What is the cost for a member to play a round of golf, and what is the cost for a nonmember?
Answer:
member = 15
nonmember = 55
Step-by-step explanation:
m = member, n= nonmember
1m+6n=345
2m + 2n =140 (divide all by 2 )
m + n = 70
m= 70 - n
70-n + 6n =345
70 + 5n = 345
5n = 345-70
5n = 275
n = 275÷5
n = 55
m = 70 - 55 = 15
m=15
The area of a square room is 125 square feet. To the nearest foot, what is the length of one side of the room?
Answer:
Side = [tex]5\sqrt5\ \text{feet}[/tex]
Step-by-step explanation:
Given that,
Area of a square room is 125 square feet
We need to find the length of one side of the room.
The area of a square shaped room is given by :
[tex]A=x^2[/tex]
Where, x is side of the square room
[tex]x=\sqrt{A} \\\\x=\sqrt{125}\\\\x=\sqrt{5\times 5\times 5}\\\\x=5\sqrt5\ \text{feet}[/tex]
So, the side of the room is [tex]5\sqrt5\ \text{feet}[/tex].

How do I find all of the angles for this and what equations would I use to find angle 2,3,4,5,7, &8?
Answer:
<2 = supplementary angle=180-110=70
<3 = supplementary angle=180-110=70
<4 = opposite angles=110
<5 = 110 (corresponding angle)
<7 = 70 (corresponding to angle 3)
<8 = 110 (corresponding to angle 4)
Step-by-step explanation:
<2 = supplementary angle=180-110=70
<3 = supplementary angle=180-110=70
<4 = opposite angles=110
<5 = 110 (corresponding angle)
<7 = 70 (corresponding to angle 3)
<8 = 110 (corresponding to angle 4)
You don't need to solve for x to find any of those angles. If you want to anyway:
4x+10=70
4x=70-10
4x=60
x=60÷4
x=15

Homework #1-18: Answer yes or no, if no give the reason
1) Is A ⊆ B given A = silver, B = {gold, silver, diamond}
A is not a set, so it can’t be a proper subset.
Answer: no, because A is not a set
3) Is C ⊆ D given C = {Phoenix}, D = {Phoenix, Glendale, Peoria, Scottsdale}
I need two rules to work.
C is a set so rule 1 is satisfied.
Every element of C is also an element of D, so rule 2 is satisfied.
Answer: yes
5) Is A ⊆ B given A = {2,3} , B = {1,2,3,4,5}
I need two rules to work.
A is a set so rule 1 is satisfied.
Every element of A is also an element of B, so rule 2 is satisfied.
Answer: yes
7) Is A ⊆ B given A = a, B = {| }
A is not a set, so it can’t be a proper subset.
Answer: no, because A is not a set
9) Is A ⊆ B given A = { }, B = {1,2,3,4,5}
Answer yes: the empty set is a subset of every set.
11) Is S ⊂ T given, S= ∅, T = {1,2,3,4,5}
Answer yes: the empty set is a subset of every set.
13) Is A ⊂ B given A = {1,2,3}, B = {3,2,1}
This is not a true statement. The sets are equal and this symbol does not allow sets to be equal.
Answer: no, sets are equal
15) Is C ⊂ D given C = {1,2,3,4,5}, D = {1,2,3,4}
Answer: no, C is not contained in D, so this is not true
17) Is A ⊂ B given A = {4,3,2,1 }, B = {1,2,3,4,5}
A is a set so rule 1 is satisfied,
A is contained in B so rule 2 is satisfied
A is not equal to B so rule 3 is satisfied
Answer: yes (all 3 rules are satisfied)
Homework #19 – 34: Determine which of these are true. (Choose every answer that is true, in

A = B, A ⊆ B, B ⊆ A, A ⊂ B, B ⊂ A, or none of these
19) A = {Trix, Captain Crunch, Rice Krispees} B = {Rice Krispees}
B is contained, but not equal to A. B is both a subset and a proper subset of A.
A is not contained in B
The sets are not equal.
Answer: B ⊆ A, B ⊂ A

5x + 10 > 35
How do you work this out?
Answer:
[tex]x > 5[/tex]
Step-by -step explanation:
Solving inequalities is similar to solving equations.
[tex]5x + 10 > 35[/tex]
Subtract 10 from both sides.
[tex]5x > 25[/tex]
Divide by 5 from both sides to isolate the x.
[tex]x > 5[/tex]
Step-by-step explanation:
[tex]5x + 10 > 35 \\ \: 5x > 35 - 10 \\ 5x > 25 \\ x > 5[/tex]

For which intervals is the function increasing? Select each correct answer.
Answer:
The answer is (2, ∞).
Step-by-step explanation:
The answer is (2, ∞) because both sides of the line will never meet and will forever increase on the [tex]y-axis^{}[/tex].
For (2, ∞) intervals is the function increasing in the graph.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
A function is increasing on an interval if for every point on that interval the first derivative is positive.
So we need to find the first derivative and then plug in the endpoints of our interval.
For interval (2, ∞) the function is increasing because both sides of the line will never meet and will forever increase on the y axis.
Hence, for (2, ∞) intervals is the function increasing in the graph.

When Joe started his job at the laundromat five years ago, his wage was $6.00 an hour. Today, his wage is $8.50 an hour. If Joe started his job in the base year, and his real wage is the same as when he started, what is the Consumer Price Index (CPI) today
Answer:
142
Step-by-step explanation:
The computation of the Consumer Price Index (CPI) today is shown below:-
Real Salary today / Real Salary 5 years ago = CPI today ÷ CPI 5 years ago
CPI today ÷ 100 = 8.50 ÷ 6
= 142
Therefore for computing the Consumer Price Index (CPI) today we simply applied the above formula and the same is to be considered

Ten oranges are to be shared between two boys in the ratio 1:4 how many will each boy get
Answer:
2 and 8
Step-by-step explanation:
Well. Boy A gets 1 orange, so the other must get 4. So say boy A gets 2 oranges now, so the other must get also double the amount of oranges, which is 8.
1:4
If you changed the 1 to a 2, you have x2 (you can only x or ÷, in ratio) on the other side. Whatever you do to this side, you do to the other side. So it becomes
2:8
Add the numbers together to find the total number of parts. You get 10 in this ratio, so it must be the answer.

Answer:B have it ✅
Step-by-step explanation:
The value of x for the given equilateral triangle is 28.
What is an equilateral triangle?A triangle having all sides equal and each angle measures 60° is called
an equilateral triangle.
Given that, the measure of each angle in an equilateral triangle is represented by the expression 2x + 4.
We know that each angle in an equilateral triangle measures 60°
Therefore, 2x+4= 60
2x = 56
x = 28
Hence, the value of x is 28.
