Tara has a magnet collection from places she visited. She measures the length of the magnets to the nearest half inch and record

gregori [183]

Answer:

there are more magnets that longer than 2 1/2

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

From the photo, we can see that:

Length of the magnet:

1 inch there is 1 magnet
$1\frac{1}{2}$ inches there are 2 magnets
2 inches there are 3 magnets
3 inches there are 4 magnets
$3\frac{1}{2}$ there is 1 magnet
4 inches there are 2 magnets

=> the total number of magnets that longer than 2 1/2 are: 4+1+2 = 7

=> the total number of magnets that shorter than 2 1/2 are: 1+2+3 = 6

Hence, there are more magnets that longer than 2 1/2

Hope it will find you well.

What is x-2y=-1 and 2x+y=4 using elimination step by step

otez555 [7]

Answer:

x = 7/5 , y = 6/5

Step-by-step explanation using elimination:

Solve the following system:

{x - 2 y = -1 | (equation 1)

2 x + y = 4 | (equation 2)

Swap equation 1 with equation 2:

{2 x + y = 4 | (equation 1)

x - 2 y = -1 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{2 x + y = 4 | (equation 1)

0 x - (5 y)/2 = -3 | (equation 2)

Multiply equation 2 by -2:

{2 x + y = 4 | (equation 1)

0 x+5 y = 6 | (equation 2)

Divide equation 2 by 5:

{2 x + y = 4 | (equation 1)

0 x+y = 6/5 | (equation 2)

Subtract equation 2 from equation 1:

{2 x+0 y = 14/5 | (equation 1)

0 x+y = 6/5 | (equation 2)

Divide equation 1 by 2:

{x+0 y = 7/5 | (equation 1)

0 x+y = 6/5 | (equation 2)

Collect results:

Answer: {x = 7/5 , y = 6/5
