Jessica lived in Spain and Colombia for a total of 18 months in order to learn Spanish.She learned an average of 160 words per m
Whitepunk [10]

Answer:

Jessica lived 10 months in Spain and 8 months in Colombia.

Step-by-step explanation:

Let x be the months Jessica spent in Spain, and y the months she spent in Colombia:

   1. x + y = 18

Using the information of words per month learned in each country, we can also write the equation:

    2. 160 * x + 200 * y = 3200

So now we have a system of <u>two equations and two unknowns</u>.

First we <u>express y in terms of x, in the first equation</u>:

  • x + y = 18
  • y = 18 - x

We <u>replace y in the second equation</u>:

  • 160 * x + 200 * (18 - x) = 3200

And <u>solve for x</u>:

  • 160x + 3600 - 200x = 3200
  • -40 x = -400
  • x = 10

Finally we <u>use that value of x in the first equation and solve for y</u>:

  • 10 + y = 18
  • y = 8

Jessica lived 10 months in Spain and 8 months in Colombia.

7/20 * 2/3 divided by 21/4
Viktor [21]
7/20 * 2/3 = 14/60 = 7/30

= 7/30 * 4/21 = 28/630 = 14/315

In short, Your Answer would be 14/315

Hope this helps!
