Answer:

(5, 1).

Step-by-step explanation:

2x+5y=15

5x+10y=35          

Multiply the first equation by -2:

-4x - 10y = -30

Add this 2 second equation:

x = 5.

Plug x = 5 into the first equation:

10 + 5y = 15

5y = 5

y = 1.

Hi!

If we multiply the top equation by (-2), then we can cancel out the y's.

-2(2x + 5y = 15)

-4x - 10y = -30

Now we add the second equation and our new equation together, and get:

x = 5

Now, we plug this in to one of the other equations

2(5) + 5y = 15

distribute

10 + 5y = 15

subtract 10 from both sides

5y = 5

divide both sides by 5

y = 1

Therefore, your answer is (5, 1)

Have a great day! :D

At one farmer’s market, bananas cost $0. 80 per pound. At another farmer’s market, bananas are sold in 5-pound bags for $4. 50 p
Minchanka [31]

To find the better buy divide 4.50 by 5 to find the unit rate for the 5-pound bag, and compare that number to $0. 80 per pound.

<h3>What is cost price per pound?</h3>

The cost price per pound is the amount of money required to buy one pound of a brand or goods.

To find the cost price per pound, divide the total amount of cost of the goods to the total number of goods.

At one farmer’s market, bananas cost $0.80 per pound.

At another farmer’s market, bananas are sold in 5-pound bags for $4. 50 per bag. To compare it with first market price, divide the 5 pound bags with $4.50.

The cost of one bag in this market is,

C=\dfrac{4.50}{5}\\C=0.5625

As this cost is less, thus, the cost of this market for one banana is less than the first market and so this is the better buy.

Hence, to find the better buy divide 4.50 by 5 to find the unit rate for the 5-pound bag, and compare that number to $0. 80 per pound.

Select the correct answer. Shape 1 and shape 2 are plotted on a coordinate plane. Which statement about the shapes is true? A. S
IceJOKER [234]

Answer:

Since I cant say which answer due to no graph, I'll tell you How to do so.

Step-by-step explanation:

if it is A, then the there is at least one angle or line length that is not the same. To find the area of a grided shape, use the traingle theorm of a^2+b^2=c^2.

if it is B, that meants moving the shape to the other will result in a perfect fit. Be sure to find if all side lengths are the same as that means that the shape IS congrouent, as equal side length means equal angles. However, it will not be this choice if the shape is mirrored to the other

A rotation and tranlastion means it is flipped either upside down or up and moved to the shape.

D, a reflection, which means its the opposite. Like a mirrored shape. Then you move it.

FINAL DUE IN 30 MINUTES: the equation 2y + x = 0 is shown on the graph below as a
julia-pushkina [17]

Answer:

Red line

Step-by-step explanation:

2y+x=0

2y=-x

y=-x/2

Put the equation into y=mx+b so you would need to subtract the x to put it on the right side so then you’ll have 2y=-x+0 then divide by 2 to get the y by itself then you’ll have y=-2x+0 that means the line would be negative and the y-intercept is 0 and the only line that follows that is the red line.
