Answer:
$2,000
Step-by-step explanation:
Since B sold the article to C at a gain of 20%, 2,640 must be 120% or 1.2 times the price that B paid.
To find the price that B paid, we just need to divide 2,640 by 1.2, as the original price multiplied by 1.2 = a 20% increase.
2,640/1.2= 2,200
The price B paid for it must have been 2,200.
Now we know that 2,200 was the price sold by A to gain 10%, therefore it is 110% or 1.1 times the original price A paid for it. Therefore, once again to find the original price, we just need to divide it by 1.1:
2,200/1.1 = 2,000
The original price it cost A was $2,000.
Hope this helped!

8x+5y=-13, 3x+4y=10 solve by elimination
8x+5y=-13
3x+4y=10
*4 on top
*5 on buttom
32x + 20y = - 52
15x + 20y = 50
subtraction
32x - 15x = - 52 - 50
17x = - 102
x = - 6
and then
3 * (-6) + 4y = 10
4y = 28
y = 7

Kendra bought 10 gallons of gasoline at $3.26 per gallon.
How much did she pay for the gasoline?
Answer:
Kendra paid $32.60 for gas.
Step-by-step explanation:
If the price of one gallon of gas is $3.26, then we should multiply that price by 10 gallons:
[tex]10(3.26)=32.6[/tex]
In context, that is a total of $32.60.
Answer: $32.60
Step-by-step explanation:
Price per gallon: $3.26
amount of gas: 10 gallons
3.26 dollars times 10 gallons = $32.60 total

Consider the trinomial x2 – 9x + 18. Which pair of numbers has a product of ac and a sum of b? What is the factored form of the trinomial?
Answer:
(x-6)*(x-3)
Step-by-step explanation:
a*c
1*18=18
Factors of 18 are:
1, 2, 3, 6, 9, 18
The equation has +18 meaning both signs must be the same; - - or + +
The only two factors that work are -3 and -6
The factored form will be (x-6)*(x-3)

ABCD is a rectangle AB=2x+4 AD=4x-2 DC=3y BC=y solve for x and y
The values of x and y in the rectangle ABCD are 1 and 2 respectively.
Properties of a rectangleOpposite sides are equal.Opposite sides are parallel.
Therefore,
AB = DC
AD = BC
2x + 4 = 3y
4x - 2 = y
Hence,
2x - 3y = -4
4x - y = 2
multiply equation(i) by 2
4x - 6y = -8
4x - y = 2
-5y = - 10
y = -10 / -5
y = 2
Therefore,
2x - 3(2) = -4
2x - 6 = -4
2x = -4 + 6
2x = 2
x = 1

Answer:
Can I get equation for this too?
Step-by-step explanation:
The dimensions of this figure are changed so that the new surface area is exactly 1/4 what it was originally.
Step-by-step explanation:
I assume the changes to the dimensions were made by using the same factor for each dimension, right ?
so, what do we need to do or calculate ? what is the desired result ?
the surface areas ? the new dimensions ? the volume ?
or only the factor of how much the dimensions changed, when the surface area was changed to 1/4 ?
????
I assume the last one, because there is so little information about what to do.
the surface area is calculated based on the areas of the various rectangles in the surface of the object.
each rectangle area is the result of multiplying 2 dimensions.
as the whole surface area shrinks by the factor 1/4, it means that every rectangle on the surface also shrinks by the factor 1/4.
and this factor 1/4 is the result of multiplying 2 dimensions. each dimension was changed by multiplying it with the same factor as every other dimension.
so, factor×factor = 1/4
factor² = 1/4
factor = sqrt(1/4) = 1/2
so, yes, in order to shrink the surface area to 1/4 of the original size, all the dimensions need to be cut in half (multiplied by 1/2).
Jared wants a quick trip by bus or train to New York. The bus’s average speed is shown in the graph. The train’s average speed is shown in the table. Which form of transportation travels a greater distance per hour?
Train
Time (hours) Distance (miles)
2 90
3 135
6 270
Bus
A graph has time (hours) on the x-axis, and distance (miles) on the y-axis. A line goes through points (0, 0) and (5, 300).
CLEAR CHECK
The train travels 5 miles more per hour than the bus.
The train travels 30 miles more per hour than the bus.
The bus travels 15 miles more per hour than the train.
The bus and train travel the same distance per hour.
Answer:
The bus travels 15 miles more per hour than the train
Step-by-step explanation:
If you look at the graph and how much the train goes per hour, it shows that in a less amount of time than the train the bus gets further. The only answer with the bus traveling further is 15 miles. Therefore, the bus travels 15 miles further per hour than the train!

Write the next three terms of the arithmetic sequence.
4, 3 3/4, 3 1/2, 3 1/4 ,__, __, __
Use the formula for an arithmetic sequence: [tex]a_{n}=a+(n-1)d[/tex]
[tex]a_{n}[/tex] = nth term
a = the first term in the sequence
n = term you are looking for
d = common difference between the terms
Answers
1. I'm assuming you meant to type 0.2, 0.6, 1, 1.4...
In that case, it is increasing by 0.4, so the next three would be:
0.2 + (4-1)(0.4) = 1.8...
=> 1.8, 2.2, 2.6.
2. Here it's reducing by 0.25, so start with:
4 + (5-1)(-0.25) = 3...
=> 3, 2.75, 2.5
The explicit formula for a sequence an = 5 – 7n . What is the value of a12?
Answer: its just 12 because a is just a variable
Step-by-step explanation: so like 5 - 7n its just 5 - 7 which in 2 so 12a is just 12
Answer:
-79
Step-by-step explanation:
an=5-7n This is the given equation
Now, we substitute 12 for n and do the equation
a(12)=5-7(12)
a(12)=5-84
a(12)=-79 This is our answer, negative 79

Ryan works two jobs. He earns $10 per hour working at the hardware store, and he earns $13 per hour working at the shipping
company. If x represents hours at the hardware store and y represents hours at the shipping company, which inequality represents
the situation if Ryan wants to earn a minimum of $300?
A)
10x + 13y s 300
B)
10x + 13y = 300
13x + 10y s 300
D)
13x + 10y = 300
Given :
Ryan works two jobs. He earns $10 per hour working at the hardware store, and he earns $13 per hour working at the shipping.
To Find :
If x represents hours at the hardware store and y represents hours at the shipping company, which inequality represents the situation if Ryan wants to earn a minimum of $300.
Solution :
His total earning is given by :
T = 10( number of hours at hardware store ) + 13( number of hours at the shipping)
T = 10x + 13y
Now, he wants to earn a minimum of $300 i.e T ≥ $300.
So, 10x + 13y ≥ 300
Hence, this is the required solution.
