Answer:

x y

2 13

4 9

5 7

6 5

Explanation:

[i] y = 17 - 2x

y = 17 - 2 × 2 = 13

[ii] y = 17 - 2x

y = 17 - 2 × 4 = 9

[iii] y = 17 - 2x

y = 17 - 2 × 5 = 7

[iv] y = 17 - 2x

y = 17 - 2 × 6 = 5

Explain how you can find the missing number and 3 4/5 divided by something equals 2 5/7 then find the missing number

enyata [817]

let's firstly, convert the mixed fractions to improper, and then do equation.

$\bf \stackrel{mixed}{3\frac{4}{5}}\implies \cfrac{3\cdot 5+4}{5}\implies \stackrel{improper}{\cfrac{19}{5}}
~\hfill
\stackrel{mixed}{2\frac{5}{7}}\implies \cfrac{2\cdot 7+5}{7}\implies \stackrel{improper}{\cfrac{19}{7}}
\\\\[-0.35em]
\rule{34em}{0.25pt}$

$\bf \cfrac{~~\frac{19}{5}~~}{x}=\cfrac{19}{7}\implies \cfrac{~~\frac{19}{5}~~}{\frac{x}{1}}=\cfrac{19}{7}\implies \cfrac{19}{5}\cdot \cfrac{1}{x}=\cfrac{19}{7}\implies \cfrac{19}{5x}=\cfrac{19}{7}
\\\\\\
\stackrel{}{\cfrac{7}{5x}=\cfrac{19}{19}}\implies \cfrac{7}{5x}=1\implies 7=5x\implies \cfrac{7}{5}=x\implies 1\frac{2}{5}=x$
