Answer:

Step-by-step explanation:

As you are looking for 1.75 minutes (or 105 seconds), the best thing to do is to find how many words she can type in 0.25 minutes (this is a quarter, and you can divide 1.75 by this). To find a quarter, you have to divide by 4, 120/4= 30. Therefore, every 15 seconds, Dorothy can type 30 words. As you've got 105 seconds, divide this by 15, and this gives you 7. Then multiply 30 by 7, and this gives you 210.
Dorothy can type 210 words in 1.75 minutes
Hope this helps :)

Answer:
Step-by-step explanation: My variables are
d=big number q=small number
My equations are 6=3q2d+3=qI
will solve for q in first equation 6/3 = 3q/32=q
Now I will pluck back in to get d2d+3=(2) -3 -32d=-12d/2=-½d=-1/4 So the solution is(-1/4, .2)
