In May, Liam and Charlie had the same amount of money in their savings accounts. In June, Liam deposited $140 into his account.
romanna [79]
Let's say both had an original amount of "a".

then Liam deposited 140, so it became a + 140.

then Charlie added 5% of "a" to "a", well, 5% of anything is just (5/100)*anything, so 5% of "a" is just (5/100) *a or 0.05a.

then they checked their amounts and both were equal, what the?  let's check.

\bf \stackrel{\textit{Liam}}{a+140}=\stackrel{\textit{Charlie}}{a+0.05a}\implies a+140=1.05a\implies 140=1.05a-a
\\\\\\
140=0.05a\implies \cfrac{140}{0.05}=a\implies \boxed{2800=a}

Solve the double integral of e^y/x dy dx with outer limits as 0 and 2 and inner limits as 0 and x^2.
jek_recluse [69]
<span> lets say integrand is e^(y/x): 
∫(x = 0 to 1) ∫(y
 = 0 to x^2) e^(y/x) dy dx 
= ∫(x = 0 to 1) xe^(y/x) 
= ∫(x = 0 to 1) x(e^x - 1) dx 
= ∫(x = 0 to 1) (xe^x - x) dx 
= (xe^x - e^x) - (1/2)x^2 

= 1/2. </span>
