Meredith bought 2/5 kg of shrimps.
Ghella [55]

Answer:

Step-by-step explanation:

if Meredith bought 20 kg and Courtney bough 10 kg less you'd do 20-10 to find how much Courtney bought, hopefully that makes sense.  We are going to do the same thing here.

That means 2/5 - 1/10.  To subtract fractions you need common denominators, like 5/6 - 1/6 = 4/6.  The bottom numbers need to be the same.  So how do we do that?  Well, that 4/6 can be rewritten as 2/3, they are the same number.  So we want to do the same with either 2/5 or 1/10... or maybe both.  Well 4/6 becomes 2/3 because 4/2 = 2 and 6/2 = 3, so we need to use that thinking.

in 2/5 - 1/10, do you see something we can multiply by to make the bottom numbers the same?  What if you multiplied 2/5 by 3 on the top and bottom?  that would get us 6/15.  Well that's too high, maybe we try 2 then.  4/10.  And hey, that got us a 10, so we idn't have to change 1/10.  Now we can do the problem.

2/5 - 1/10 = 4/10 - 1/10 = 3/10.

So Courtney bought 3/10 kg

To find the total weight we add.  So now we have a similar problem.

2/5 + 3/10  Well we know what to change 2/5 to to get a 10 at the bottom.  

2/5 + 3/10 = 4/10 + 3/10 = 7/10.

So in total they bought 7/10 (seven tenths) of a kilogram.  

Let em know if something didn't make sense.

Write an equation for the line in slope-intercept
Lemur [1.5K]

Answer:

  • y = 3x + 5

Step-by-step explanation:

<u>Slope-intercept form:</u>

  • y = mx + b, where m is the slope, b is the  y-intercept

<u>Take two points from the graph:</u>

  • (-2, -1) and (0, 5)

<u>Find the slope:</u>

  • m = (5 - (-1))/(0 - (-2)) = 6/2 = 3

The y-intercept is b = 5

<u>The line is:</u>

  • y = 3x + 5
