Tell whether the equation has one, zero, or infinitely many solutions.9(x − 3) + 15 = 9x − 11.
Answers
Answer:
Zero solutions; there are no variables and thus there are no solutions
Step-by-step explanation:
We start out with the equation 9 (x - 3) + 15 = 9x - 11
Which simplifies to 9x - 27 + 15 = 9x - 11
The 9x terms cancel each other out, and we're left with 15 - 27 = -11
And we end up with -12 = -11, which is not true.
This tells us that the equation has zero solutions, because no matter what value we substitute for x, the equation will not be true.
Answer:
No solution
Step-by-step explanation:
9(x-3)+15= 9x-11
9x-27+15=9x-11
-15 on both sides
9x-27=9x-26
add 26 on both sides
9x -1=9x
add 1 on both sides
9x=9x+1
divide 9 on both sides
x=x+1/9

What is the equation of line?The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.
Given that,
The point,
x = 8 and y = 2
We have to check all the given options,
1. y = 1/4x
y = 1/4 × 8

In 2011, a professional climber scaled the outside of the Burj Khalifa, making it all the way to 828 meters (the highest point on which a person can stand) in 6 hours.
Answers
Answer:
276 meters in the first 2 hours
Step-by-step explanation:
Given that,
Professional climbers climb 828 meters in 6 hours.
Let us assume we need to find how far did they climb in the first 2 hours.
6 hours = 828 m
⇒ 1 hour = 138 m
So, in 2 hours,
2 hours = 138 × 2 m
= 276 m
So, the climber climb 276 meters in the first 2 hours

A field is in the form of a rhombus having each side 81 m and altitude 25 m. What is the side of a square
field which has the same area as that of the rhombus?
Answers
Answer:
the side of a square is 45 m
Step-by-step explanation:
The computation of the side of the square field that contains the similar area as compared with rhombus is given below:
As we know that
Area of rhombus = Base × Altitude
= 81 × 25
= 2025
And, area of Square = Side × side
2025 = side^2
side = √2025
= 45m
Hence, the side of a square is 45 m

Step-by-step explanation:
amount of discount = $10
percentage discount = $10/$39.99 ≅ 0.25 = 25%
amount of sales tax = $1.95
sales tax rate = $1.95/$29.99 ≅ 0.065 = 6.5%
cost of jeans × 1.60 = $39.99
cost of jeans = $39.99/1.60 ≅ $24.99
discounted selling price = $29.99
markup = $29.99/$24.99 ≅ 1.20 = 20%

The cost of a house is 13% in one year. The original price was 75,000. Find the cost of one year later
Answers
Answer:
The cost of the house after one year = 84,750 rupees
Step-by-step explanation:
Explanation:-
Given that the cost of house = 13% in one year
Given that the house original price = 75000
We have to find that the house cost after one year
Solution:-
The cost of a house increase 13% per year
= 75000 X 0.13
= 9750
The total cost = 75000+9750
= 84,750 rupees
Final answer:-
The cost of the house after one year = 84,750 rupees

349 + 4.80n
3
135
Step-by-step explanation:
1
For this, use the equation I gave you above to find the costs.
2
First, the cost of the printer will NOT change, for the number of printers Eddie needs to buy does not change, he only needs one. This already helps you figure out that 349 is not a coefficient to the variable, n. However, when it comes to the number of blank shirts Eddie needs to buy, the number of he gets does change, this is the dependent variable that makes the cost vary. Using the equation above, you can plug in any number.
For example, 20.
349 + 4.80(20) = 445
3
For this final part, I just kept using the equation until I got the closest number that is lower than 1000. In this case, 135 got me 997, and 136 was just a few decimals away from 1000, but it was still over.

Two trains, Train A and Train B, weigh a total of 379 tons. Train A is heavier than Train B. The difference of their weights is 255 tons. What is the weight of each train?
Answers
Answer: A = 317
B = 61
Step-by-step explanation:
The following equation can be gotten from the question given. This will be:
A + B = 379 ........ i
A - B = 255 ........ ii
From equation i, make A the subject of the formula
A = 379 - B ...... iii
Put the value of A in iii into equation ii
A - B = 255
(379 - B) - B = 255
379 - B - B = 255
379 - 2B = 255
2B = 379-255
2B = 124
B = 124/2
B = 62 tons
Since A + B = 379
A + 62 = 379
A = 379 - 62
A = 317 tons

Amanda bought tickets for a concert for $218. Jamie bought tickets to the same concert but paid 14% less than Amanda. What were the price of Jamie's tickets?
Answers
Answer:
Jamie's tickets = $187.48
Step-by-step explanation:
The amount for which Amanda bought tickets = $218
Jamie bought tickets to the same concert but paid 14% less than Amanda.
Jamie's tickets = [tex]218-14\%\ of\ 218[/tex]
We can solve it as follows :
[tex]218-14\%\ of\ 218=218-\dfrac{14}{100}\times 218\\\\=218-30.52\\\\=\$187.48[/tex]
So, the price of Jamie's tickets is $187.48.
How long does it need to keep $600 in an account that pays 2.75% annual simple interest to earn $264?
Answers
Answer:
16 years
Step-by-step explanation:
Principal amount (P) = $600
Rate of interest (R) = 2.75%
Simple interest (S.I.) = $264
Let t denotes time period.
[tex]S.I.=\frac{PRT}{100}[/tex]
[tex]264=\frac{600(2.75)t}{100} \\\\t=\frac{264(100)}{600(2.75)}[/tex]
[tex]t=16[/tex] years.
Therefore,
interest of $264 will be earned in 16 years.
