How many different ways can you write a fraction that has a numerator of 2 as a sum of fractions

At least you can write it as the sum of half of it twice, that is:
2/x = 1/x + 1/x
whatever x number you have, for example:
2/5 = 1/5 + 1/5

But then, you can express a fraction in many different ways, for example again:
2/5 = <span>1/5 + 1/5 = 2/10 + 2/10
</span>= 1/10 + 1/10 + 1/10 + 1/10
so there are an infinite ways of expressing such a fraction.

Yuki888 [10]

Answer: p*$4 + d*$3 ≥ $24

Step-by-step explanation:

The price P of popcorn is P = $4, the pricec of a drink is D = $3

He only has $24

The equation that represents the number of popcorns and drinks he can buy us:

p*$4 + d*$3 ≥ $24

This means that the maximum amount of money he can spend is $24.

In this equation you can give the value of p or d, and then find the maximum possible value for the other variable.

Find the inverse Laplace transform of F (s)=2/s^3
IceJOKER [234]

Recall that for integers <em>n</em> > -1,

L_s\left\{t^n\right\} = \dfrac{n!}{s^{n+1}}

Then

\displaystyle L^{-1}_t\left\{\frac2{s^3}\right\} = L^{-1}_t\left\{\frac{2!}{s^{2+1}}\right\} = \boxed{t^2}

Which set of side lengths shows similar triangles?
lbvjy [14]
The correct answer is D or the last choice. First, Pair up the values of both triangles in descending order then divide it. Having the equal answer will conclude that both triangles are similar.

A.(32/30) = (32/16) = (20/16)
    1.067 = 2 = 1.25 = false
B. (110/8) = (80/6) = (60/5.5)
     13.75 = 13.33 = 10.90 = false
C. (50/12.5) = (40/10) = (20/10)
    4 = 4 = 2 = false
D. (60/30) = (30/15) = (30/15)
      2 = 2 = 2 =True

ABC and CBH are right angles

DBC = 90 - 37 = 53
CBJ = 90 - 31 = 59

HBD = 180 - 37 = 143
or
HBD = 31 + 53 + 59 = 143 :)
