It takes a word processor 22 minutes to word process and spell check 4 pages. Find how long it takes her to word process and spe

krek1111 [17]

We are given

It takes a word processor 22 minutes to word process and spell check 4 pages

so, firstly we can find rate

total time =22 min

number pf pages =4

processing rate = ( number of pages)/( total time)

So, processing rate is

$=\frac{4}{22}$

$R=\frac{2}{11}$ page /min

now, we are given total number of pages =26

Time = (total number of pages)/( processing rate)

so, time is

$=\frac{26}{\frac{2}{11}}$

now, we can simplify it

$=\frac{26}{\frac{2}{11}}$

$=143$

So, the time taken to word process and spell check 26 pages is 143 min........Answer

What is the equation if x=1 and y=16/3

GaryK [48]

There may be more than one way in which to answer this question. I will assume that the "equation" is a linear one: f(x) = mx + b.

Then (16/3) = m(1) + b
This is one equation in two unknowns, so it does not have a unique solution. Was there more to this problem than you have shared?

If we assume that the y-intercept (b) is zero, then y = mx, and

16/3 = 1m, so that m = 16/3, and so y = (16/3)x.
