On average she can knit 2cm in 35 minutes express this as a rate in mm/minutes
​

17.142858mm Per Minute

Step-by-step explanation:

First divide 2 by 35 to get 0.057148286 which you then divide by 2 because knitting 1cm should take half the time of 2cm to get 0.02857143;

1cm is equal to 10mm SO we multiply the final value of the calculation I shared before by 10 to get 0.2857143 which would be 1/60 of the answer since there are 60 seconds per minute so FINALLY we multiply the 0.2857143 by 60 to find that she can knit 17.142858 mm per minute!

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

2x^2+5x+17

your welcome. : )
