How do I work this problem out?

This is asking for the cube root of 64. Another way of phrasing this is "What number cubed is equal to 64?" We know that 2³ is 8, so it must be a number greater than 2. 3³ is 27, it must be larger. 4³ is equal to 64, so 4 is your answer.

Answer:

y+22

Step-by-step explanation:

I think you meant the variable as lower case, sorry if I misinterpreted, but...

Increased by just means addition. so y increased by 22 would translate to y+22.

using the LCD method.... well, there are a couple of ways, but let's simply add them up.

well, the denominators are 5x and 2x... so the only LCD will just be 10x, since it's divisible by both, so let's use that one.

$\bf \cfrac{2}{5x}+\cfrac{7}{2x}=1\implies \stackrel{\textit{LCD of 10x}}{\cfrac{(2)2~~+~~(5)7}{10x}}=1\implies \cfrac{4+35}{10x}=1\implies \cfrac{39}{10x}=1 \\\\\\ 39=10x\implies \cfrac{39}{10}=x\implies 3\frac{9}{10}=x$
