Answer:
x=-2
Step-by-step explanation:
x-27 = 7x -15
subtract x from both sides
-27=6x-15
add 15 to both sides
-12=6x
divide both sides by 6
-2=x
x=-2
Answer:
x=-2
Step-by-step explanation:
x-27=7x-15(move variable left hand side /change sign)
x-7x-27=-15
x-7x=-15+27
-6x=-15+27
-6x=12
x=-2
How many solutions will this equation have? 2(x + 4) = 2x + 8
Answer:
None
Step-by-step explanation:
This type of equation is a tautology, it will always be true
We want to see how many solutions does the given equation has.
We will see that the equation has infinite solutions.
The given equation is:
2(x + 4) = 2x + 8
To find how many solutions it has, we need to solve it, we first can distribute the product at the left to get:
2(x + 4) = 2x + 8
2x + 2*4 = 2x + 8
2x + 8 = 2x + 8
Note that we have the exact same thing in both sides, so the value of x can be any real number, and the equation will still be true.
This means that there are infinite solutions for the given equation.

SYSTEMS OF EQUATIONS WORD PROBLEM: The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds 500 people. By selling tickets, the members would like to raise $3,350 every night to cover all expenses. Let d represent the number of adult tickets sold at $8.50. Let s represent the number of student tickets sold at $5.50 each. If all 500 seats are filled for a performance, how many of each type of ticket must have been sold for the members to raise exactly $3,350? At one performance there were two times as many student tickets sold as adult tickets. If there were 360 tickets sold at that performance, how much below the goal of $3,350 did ticket sales fall?
first question: Number of student's ticket(s) = 400
And number of adult's ticket(d) = 100
Second question: The goal of $3050 fell by $710

How would I find the perimeter? Thank you!
Answer:
138
Step-by-step explanation:
We will use this multiple times so first note that when two tangents meet at a point, the distance to where they touch the circle from that point is equal.
This means 7y-9=2y+11 so 5y=20 so y = 4
OK = NK = 7y-9 = 7(4)-9 = 28-9 = 19
This means the length ML = OL = 32 - OK = 32 - 19 = 13
JM = JN
5x-8=8x-35
27=3x
x=9
So JM=JN=5(9)-8 = 45 - 8 = 37
Now the perimeter = JM + ML + OL + OK + NK + JN = 37 + 13 + 13 + 19 + 19 + 37 = 138

$2200 at 7.5% for 3 1/4 year what is the interest rate
Answer:
$536.25
Step-by-step explanation:
First you find what 7.5% of $2200 is,
(2200/100)7.5=165
Then, you multiply 165 by 3 1/4 to find how much interest is accumulated over 3.25 years
165)3.25=536.25

plzz fasstttt i need to writw this!!!!!!!!!
Answer:
Step-by-step explanation:
LHS = (Cos9° + Sin9°) / (Cos9° - Sin9°)
Divide by Numerator and Denominator by Cos9°
LHS = (1 + Tan9°) / (1 - Tan9°)
= (Tan 45° + Tan 9°) / (1 - Tan 45° * Tan 9°)
= Tan (45°+9°)
= Tan 54°
= Cot 36°

Solve for x.
Please help !
Answer:
x = 37 1/2x = 2Step-by-step explanation:
Parallel lines divide transversals proportionally. I like to write the proportions so the variable is in the numerator. Then the solution is obtained by multiplying by the denominator of the variable term.
1. x/20 = (46 -16)/16
x = 20(30/16)
x = 37.5
__
2. (x +4)/13.5 = 4/9
x +4 = 13.5(4/9) = 6
x = 6 -4
x = 2
sarah recives an inheritance of 180000.she decided to invest this for the next five years as part of her saving plan for a housing deposit. The first year she puts the money in the bank and earns 5.75% per annum interest.How much does she have at the end of the first year ?
Answer: 10350
Step-by-step explanation:
Amount invested = Principal = 180,000
Interest rate = 5.75%
Time = 1 year
The interest that is earned at the end of the first year will be:
= PRT
= 180,000 × 5.75% × 1
= 180,000 × 0.0575 × 1
= 10350

Can a set of data have more than one line of best fit? Why or why not?
2 Answers. It is certainly possible (in mostly silly cases). For example, suppose you sample the same x value twice and get two experimental y values that differ. One such case might be getting the points (0,−1) and (0,1) if we sample x=0 twice.
Answer:
yes because for data you need more than one line.

What is the surface area for this design?
Answer:
Surface Area = 157 in^2
Step-by-step explanation:
Surface area is the area of each side added together.
