A washing machine is filling up with water at a constant rate. The rate is Three-fourths of a gallon in StartFraction 1 over 5 EndFraction of a minute. Don calculated the unit rate to be StartFraction 3 over 20 EndFraction of a gallon per minute. What did he do wrong? He added Three-fourths to StartFraction 1 over 5 EndFraction instead of multiplying Three-fourths by StartFraction 1 over 5 EndFraction. He divided Three-fourths by StartFraction 1 over 5 EndFraction instead of multiplying Three-fourths by StartFraction 1 over 5 EndFraction. He added Three-fourths to StartFraction 1 over 5 EndFraction instead of dividing Three-fourths by StartFraction 1 over 5 EndFraction. He multiplied Three-fourths by StartFraction 1 over 5 EndFraction instead of dividing Three-fourths by StartFraction 1 over 5 EndFraction.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
