40.82 kg beacause one kg is 2.20462 pounds so if you add all that together it all adds up to that.

1 kg = 2.2 lb
to set up your proportion
- put your given over one
90lb / 1
then multiply that by you conversion factor which is 1 kg = 2.2 lb
90lb/1   x   1kg/2.2lb
since you have lb on both the top and bottom that unit would cancel out leaving you with kg
if you multiply straight across you get 90 x 1 = 90 and 1 x 2.2 = 2.2
now you just divide the top number by the bottom number 90 ÷ 2.2 = 40.91 kg

Find the value of $x$ so that the ratios are equivalent.<br><br> x:5/2 and 8:10
Scrat [10]

Answer:

x=2

Step-by-step explanation:

Here what we need is that the ratios be equal, which is:

x:(5/2) = 8:10 or, what is the same:

x/(5/2) = 8/10

Lets pick the left term x/(5/2) and multiply both numerator and denominator by 2 to eliminate the fraction on the denominator:

2x/2(5/2) = 2x/5

Now, we would like to make a 10 appear on the denominator. As we already have a five we need to multiply numerator and denominator by the num that, multiplied by 5 gives as 10, this is 2:

2(2x)/2(5) = 4x / 10

So, we transformed x/(5/2)  in 4x/10, and both are the same, so we can replace it on our first equation:

4x/10 = 8/10

As both denominators are equal, we can concentrate only in numerators:

4x = 8

Dividing both sides by 4:

x = 2

So, for x=2 both ratios are equivalents.
