(You might consider this dumb.) I have been struggling with maths lately and I feel like I can't do the simplest of problems, and my mother won't help me as she just thinks I'm being lazy. I'm really struggling with a lesson. I'm in 7th grade. Can someone tell me how to combine like and unlike terms with fractions that have variables? I just can't figure it out and no one can really help me right now.

well to combine like terms you just add up all the numbers with the same variables /letters for example: 3/4y + 3/4y = 1   1/2y

Step-by-step explanation:

the circle one

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
