Sandra's printer can print 5 pages in 2/3 of a minute (40s). Show different ways to determine how many pages her printer can pri

Ne4ueva [31]

Answer:

$7\frac{1}{2}$ pages

Step-by-step explanation:

Method 1: Working with minutes

Let us assume that, Sandra's printer can print x pages in 1 minute.

Then we can write the equation:

$x:1=5:\frac{2}{3}$

We can rewrite the ratios as a fraction.

$\frac{x}{1}=\frac{5}{\frac{2}{3}}$

This simplifies to

$x=\frac{15}{2}$

$x=7\frac{1}{2}$

Method 2: Working with seconds

If 5 pages corresponds to 40 seconds, then we can write: $5:40$

Let y corresponds to 60 seconds (1 minutes).

Then:

$y:60=5:40$

We rewrite as fraction:

$\frac{y}{60}=\frac{5}{40}$

Multiply both sides by:

$y=\frac{5}{40}\times 60$

$y=\frac{300}{40}$

$y=\frac{15}{2}$

$y=7\frac{1}{2}$

(a) Complete the table of values for y = 6 - 4x. Please help ❤️

shutvik [7]

Answer:

$\boxed{\begin{tabular}{|c|c|c|c|c|c|}\cline{1-6} \bf x & -1 & 0&1&2&3\\\cline{1-6} \bf y & 10& 6& 2&(-2)&-6 \\\cline{1-6}\end{tabular}}$

Step-by-step explanation:

Given equation to us is :-

$\implies y = 6 - 4x$

So , here we can put different values of x in order to get different values of y .

Initial table given to us is ,

$\begin{tabular}{|c|c|c|c|c|c|}\cline{1-6} \bf x & -1 & 0&1&2&3\\\cline{1-6} \bf y & & & 2&&-6 \\\cline{1-6}\end{tabular}$

Put x = (-1) :-

$\implies y = 6 - 4x \\\\\implies y = 6 -4(-1) \\\\\implies y = 6 + 4 \\\\\red{\bf\implies y = 10}$

Put x = 0 :-

$\implies y = 6 - 4x \\\\\implies y = 6-4(0) \\\\\implies y = 6 - 0 \\\\\pink{\bf\implies y = 6 }$

Put x = 2 :-

$\implies y = 6-4x \\\\\implies y = 6 - 4(2) \\\\\implies y = 6 - 8 \\\\\blue{\bf\implies y = (-2)}$

Hence the final table would be :- 

$\begin{tabular}{|c|c|c|c|c|c|}\cline{1-6} \bf x & -1 & 0&1&2&3\\\cline{1-6} \bf y & 10& 6& 2&(-2)&-6 \\\cline{1-6}\end{tabular}$
