Answer:
y = 3
Step-by-step explanation:
-3(2/3) + 5= y
-3 * 2/3 = -2
-2 + 5 = 3
So the answer is y = 3

The bids in an online auction are represented by the arithmetic sequence shown below: right on explicit formula to represent the bids as an arithmetic sequence. What is the tenth bid
Answer:
10th bid is 292
Step-by-step explanation:
Here, as we can see, we have an arithmetic sequence and we want to calculate its 10th term
From the question, we can see that the first term a is 193
The common difference is 204-193 = 11
The formula for the nth term of a sequence is;
a + (n-1)d
In this case, n = 10
so we have ;
193 + (10-1)11
= 193 + 99 = 292

A general arranges his students to form a perfect square.He finds that in doing so 60 soldiers were left out if total number of soldiers be 8160 find the number of soldiers in each row
Answer:
90
Step-by-step explanation:
Given that :
Number of soldiers = 8160
Number left out = 60
Result of arrangement gives a perfect square ;
Hence, the number of soldiers which makes up the arrangement will be ;
Total number of soldiers - number left out
8160 - 60 = 8100
Hence 8100 soldiers were used to form a perfect square ;
Number of soldiers in a row :
√8100 = 90
Hence, we have 90 soldiers in a row

Step-by-step explanation:
5 - 4 + 7x + 1 = 7x + 2.
If there are no solutions, then it is of the form 7x + c, where c is any real number besides 2.
If there is 1 solution, then it is of the form mx + c, where m is any real number besides 7 and c is any real number.
If there are infinitely many solutions, then it is of the form 7x + 2.

find the value of x in each of the given triangles.
Answer:
x= 12°
Step-by-step explanation:
The angle measures in the triangle are given as;
A = 4x
B= 5x
C= 6x
The sum of angle measures in a triangle add up to 180°
Applying the statement in an equation as;
4x + 5x + 6x = 180°
15x = 180°
x= 180° / 15
x = 12°
The distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter represents 20 kilometers. What is the actual distance between these two cities in kilometers?
Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.
Answer:
70 km
Step-by-step explanation:
[tex]\frac{3.5 cm}{x km}[/tex] = [tex]\frac{1cm}{20km}[/tex]
x = (3.5 cm × 20 km) ÷ 1 cm = 70 km
Answer:
70 km
Step-by-step explanation:
Enter the x coordinate of the solution to this system of equations.
- 2x + y = 5
– 5x + y = – 4
Answer:
x = 3
Step-by-step explanation:
Given the 2 equations
- 2x + y = 5 → (1)
- 5x + y = - 4 → (2)
Multiply (2) by - 1 then add to (1) to eliminate y
5x - y = 4 → (3)
Add (1) and (3) term by term to eliminate y
3x = 9 ( divide both sides by 3 )
x = 3

A park has a 3m tall tetherball pole, and a 6.8m tall flagpole. The lengths of their shadows are proportional to their heights.
Complete question is;
A park has a 3 meter tall tether ball pole and a 6.8 m tall flagpole. The lengths of their shadows are proportional to their heights.
Which of the following could be the lengths of the shadows?
Choose 2 answers from the options attached.
Answer:
Options B & D
Step-by-step explanation:
From the question, the proportional relationship between the height and shadow length is a direct proportionality. This means that an increase in the height, leads to an increase in the length of shadow and vice versa. Thus, the height to shadow length ratio is a constant.
Now, if we use x and y to denote length of shadow of tether ball pole and length of flagpole receptively, we will have;
3/x = 6.8/y
Let's make y the subject.
y = 6.8x/3
Looking at the options;
Option A: When x = 1.35 m, we have;
y = (6.8 × 1.35)/3 = 3.06 m
For Option B:
When x = 1.8 m,
y= (6.8 × 1.8)/3 = 4.08 m
For Option C:
When x= 3.75 m,
y = (6.8 × 3.75)/3 = 8.5 m
For option D:
When x = 0.6
y = (6.8 × 0.6)/3 = 1.36 m
For option E;
When x = 2,
y = (6.8 × 2)/3 = 4.533 m
From our calculations, the only values of y that correspond with the given value of y in the options are Options B & D

Calculate the marked price of a sweater purchased at Rs. 1075 allowing 14% discount. ( please do proper answer )
Answer: $1225.50
Step-by-step explanation:
Purchase price = $1075
Discount Percent = 14%
Discount = 14% × $1075
= 0.14 × $1075
= $150.50
Marked price = Purchase price + Discount
= $1075 + $150.50
= $1225.50

New York and Denver are in different time zones. When it is noon in New York, it is 10:00 a.m. in Denver. At 2:00 p.m. in New York, a train departs, and it arrives in Denver 45 hours later. What time is it in Denver when the train arrives?
Answer:
9:00 AMStep-by-step explanation:
Time in New York = noon = 12:00 PMTime in Denver = 10:00 AMTime difference = -2 hours
Train departs at 2:00 PMTravel time = 45 hoursTrain arrival time:
2:00 PM + 45 hours = 2:00 PM - 3 hours (plus 2 days) = 11:00 AMConverting to Denver time:
11:00 AM - 2 hours = 9:00 AMAnswer:
9:00 AM
Step-by-step explanation:
Un camión admite en su interior 68,25 toneladas de patatas. Se cada caja de patatas pesa 22,75 Kg, ¿cuántas cajas de
patatas lleva el camión?
Answer:
El camión lleva 3000 cajas de patatas
Step-by-step explanation:
Proporciones
La capacidad de carga de un camión es de 68.25 Toneladas de patatas.
Como 1 tonelada es equivalente a 1000 Kg, expresamos la capacidad en Kg:
68.25 * 1000 = 68250 Kg
Cada caja de patatas pesa 22.75 Kg, luego el número de cajas que caben en el camión son:
68250/22.75 = 3000 cajas
El camión lleva 3000 cajas de patatas
help me find the answer lol
Answer:
First/Top graph.
Step-by-step explanation:
First, we need to solve the inequality for n:
-6n + 5 < 11 (Given)
-6n < 6 (Subtracted 5 on both sides)
n > -1 (Divided -6 on both sides)
NOTE: Whenever you multiply or divide by a negative number when dealing with inequalities, the sign switches.
Now that we know that n > -1, we need to look for a graph that has an open circle on the point -1 and goes in the right direction.
Therefore, the first graph is the correct answer.

A ,B and C average is 45 ,b and C average is 40 then find b
This question is incomplete
Complete Question
The average weight of A, B and C is 45 kg. If the average weight of A and B be 40 kg and that of B and C be 43 kg, then the weight of B is :
Answer:
31 kg
Step-by-step explanation:
From the above question:
A ,B and C average is 45.
Hence, the total values of A, B, C is calculated as:
A + B + C /3 = 45
A + B + C = 45 × 3
A + B + C = 135
Also,
B and C average is 43
The total values of B, C is calculated as:
B + C /2 = 43
B + C = 43 × 2
B + C = 86
A and B average is 40
The total values of A, B is calculated as:
A + B /2 = 40
A + B = 40 × 2
A + B = 80
Hence:
A + B + C = 135
B + C = 86
A + B = 80
Hence, we can solve for A, we substitute 80 for A + B
80 + C = 135
C = 135 - 80
C = 55kg
B + C = 86
B + 55 = 86
B = 86 - 55
B = 31 kg

Enjal paid Rs 15,255 for smart phone with 10% discount and 13% vat. Find marked price of that smart phone.
Answer:
The marked price of the smart phone is Rs 15,000.
Step-by-step explanation:
We proceed to explain step by step how to determine the marked price of the smart phone:
1) Divide the resulting price by the VAR factor:
[tex]C' = \frac{C''}{1 + \frac{r}{100} }[/tex] (1)
Where:
[tex]C''[/tex] - Resulting price, measured in rupees.
[tex]C'[/tex] - Price of the product after discount, measured in rupees.
[tex]r[/tex] - VAT rate, measured in percentage.
If we know that [tex]C'' = 15,255\,INR[/tex] and [tex]r = 13[/tex], then the price of the product after discount is:
[tex]C' = \frac{15,255\,INR}{1+\frac{13}{100} }[/tex]
[tex]C' = 13,500\,INR[/tex]
2) Divide the price of the product after discount by the discount factor:
[tex]C = \frac{C'}{1-\frac{r'}{100} }[/tex] (2)
Where:
[tex]C[/tex] - Marked price of the product, measured in rupees.
[tex]r'[/tex] - Discount rate, measured in percentage.
If we know that [tex]C' = 13,500\,INR[/tex] and [tex]r' = 10[/tex], then the marked price of the product is:
[tex]C = \frac{13,500\,INR}{1-\frac{10}{100} }[/tex]
[tex]C = 15,000\,INR[/tex]
The marked price of the smart phone is Rs 15,000.
