Matthew has two kinds of rice show i this table. 8 7/8 and 6 3/4. How much more brown rice than white rice does Matthew have?
Serjik [45]

let's firstly convert the mixed fractions to improper fractions and then get their difference.

\stackrel{mixed}{8\frac{7}{8}}\implies \cfrac{8\cdot 8+7}{8}\implies \stackrel{improper}{\cfrac{71}{8}} ~\hfill \stackrel{mixed}{6\frac{3}{4}}\implies \cfrac{6\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{27}{4}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{71}{8}-\cfrac{27}{4}\implies \cfrac{1(71)~~ -~~2(27)}{\underset{\textit{using this LCD}}{8}}\implies \cfrac{71-54}{8}\implies \cfrac{17}{8}\implies 2\frac{1}{8}

Answer:

(a) Output = 37

(b) Input = 9

Step-by-step explanation:

Given

y =x5 - 3

Solving (a): Output, when input = 8

This means that, we solve for y when x = 8

So, we have:

y =x5 - 3

y =8*5 - 3

y =40 - 3

y = 37

Solving (b): Input, when output = 42

This means that, we solve for x when y = 42

So, we have:

y =x5 - 3

42 = x5 - 3

Collect like terms

x5 = 42 + 3

x5 = 45

Divide both sides by 5

x = 9
