2A bag contains only red and blue marbles. Yasmine takes one marble at random from the bag. The probability that she takes a red marble is 1 in 5. Yasmine returns the marble to the bag and adds five more red marbles to the bag. The probability that she takes one red marble at random is now 1 in 3. How many red marbles were originally in the bag?
10 red
3 red
5 red
2 red

Answers

Originally, there were
x = 5 red
4x = 20 blue

Now, there are
x+5 = 10 red
4x = 20 blue


A jacket is discounted 30% off. The original was $150.00. What is the new price of the jacket after the discount?

Answers

$105. 30% of 100 is 30 and 30% of 200 is 60 it'd be 45 off because it's the number between the 2. Leaving 150-45=$105
$50. So, first we have to take the original price and divide it. $150.00 divided by 3 equals $50.

Draw a line through each point using the given slope. What do you notice about the two lines? Slope = 1/2Number 3 please

Answers

I believe what it is asking is that you draw a line through one point using the given slope. Then you do the same for the second.

If you did this right you should notice that the lines are parallel die to the fact that they have the same slope.

Final answer:

When you draw a line through each point with a slope of 1/2, the two lines you create will be parallel to each other because they both have the same slope and increase at the same rate.

Explanation:

In mathematics, a slope of 1/2 means that for every 2 units you move to the right (horizontally), you will move up 1 unit (vertically). When you draw a line through each point using this slope, you'll notice that the two lines will be parallel to each other. That's because they both have the same slope, which means they're increasing at the same rate. Therefore, they never intersect and remain an equal distance apart from each other at all points.

Solve for x in the equation:3 over 7 x + 5 = 8
— please help i will give brainliest!

Answers

Answer:

3/7 x +5=8

move 5 to the other side

3/7 x= 8-5

3/7 x= 3

then move 7 to the other side it's sign is ÷ it will be ×

then 3x=3×7

3x=21

then move 3to the other side it's sign is × it will become ÷

x= 21/3

x= 7

Answer:

x=7

Step-by-step explanation:

34 + 6x = 2 + 4(4x - 7)

Answers

x = 6

distribute the bracket on the right side of the equation and simplify

34 + 6x = 2 + 16x - 28

34 + 6x = 16x - 26 ( subtract 16x from both sides )

34 - 10x = - 26 ( subtract 34 from both sides )

- 10x = - 60 ( divide both sides by - 10 )

x = 6
So basically it's a lot of collecting like terms, but x=6

a store owner is arranging clothing on racks. She has 30 sweaters, 45 shirts and 15 pairs of jeans. She wants to put the same number of items on each rack, with only one type of item on each. How many items can she put on a rack?

Answers

I think what the teacher wants is 15  which is the greatest common factor of all three numbers and the factors of 15 are 
1 x 15 and 3 x 5 so the she can put one of each, or she can put 3 of each,
 or she can put 5 of each , or she can put 15 of each.

The problem is unclear however because as worded she could put 2 sweaters, 2 shirts and 2 pair of jeans.  I think the teacher wants all the jeans used.  The number 1,3,5 and 15 will use up all of the jeans.
1 jean on 15 racks
or 3 jeans on 5 racks
or 5 jeans on 3 racks
or 15 jeans on one rack

These are the sort of ambiguous word problems 4th graders are exposed to on a daily basis.  As the gentleman mentioned, the teacher expects 15, the largest common factor but 1 on each rack fits as well. It should have read “what’s the maximum number of the same item can he/she place on the racks?”
