The old bag of marbles contains 4 blue and 3 red marbles. If you were to double the number of red and blue marbles to create a NEW bag, would the chance of pulling out a blue marble be the same as pulling a blue marble from the old bag? (this is for math class by the way-)

Answers

Answer 1

Answer:

The chance will be the same (4/7)

Step-by-step explanation:

Old bag

p(blue)=4/7

New bag

p(blue)=8/14=4/7

The chance will be the same (4/7) since both the red and the blue marbles are doubled at the same time implying that the ration of red to blue still remails the same.

I hope the explanation is clear. If so rate brainliest please

You decide to buy a custom frame for a painting which measures 4 by 6 inches. If the framing material costs $2 per inch, what is the total cost of framing material?

Answers

Answer:

6 x 4 = 24 x $2 = $48

Step-by-step explanation:

The total cost of the rectangular frame is C = $240.

What is rectangle?

A rectangle is a two-dimensional shape in which the opposite sides are parallel and equal to each other and all four angles are right angles.

Given that, a painting measures 4 by 6 inches, the framing material costs $2 per inch,

We need to find the total cost of framing material

The perimeter is given by:

P = 2x(L + W)

In this case, we know that the frame is 6 inches by 14 inches, then the perimeter will be:

P = 2x(6in + 14in)

P = 2x20in = 40in

Since, the framing material costs $6 per inch, then the total cost of the frame will be:

cost = 40x$6 = $240

2x + 5y = -24
3x - 5y = 14
Solve by elimination
y and x

Answers

Answer:

x = -2

y = -4

Step-by-step explanation:

The way systems of equations  work is that you have to substitute to solve for a variable *(only one of the 2 ways to figure this out)*

so, we will use addition property of equality in a form to add the two equations together, since +5y and -5y added together will cancel out.

that would leave

5x = -10

divide both sides by 5

x = -2

Now that we know x = -2, we can plug in -2 into one of the equations to find y.

2 ( -2)  + 5y = -24

-4 + 5y = -24

-4 + 4 + 5y = -24 + 4

5y = -20

y = -4

x = -2

y = -4
