9 + 5x- 5 + 3x = 4+8x = 4(1+2x)
2x+9-x+3 = x+12
7x+5-2x+8 = 5x +13
combine like terms and add and subtract
hope this helps XD have a wonderful break
Answer:
Is george included in the 36kg or what. If that is the case.
Step-by-step explanation:
Weight of 2 cats = 36 - 30 = 6
1 cat = 6 ÷ 2 = 3 kg
2005= 18,000
2010= 45,000
1) make 2005 year "0", and 2010 year "5"
2)in order to solve this problem and figure out the rate of change, we must use the equation for exponential functions y=ab^x
3) a= the y- value of y intercept ( what does y equal when x is zero) in this case a population number so, a= 18,000; b= the unknown rate of change; x= time and since we're finding b we can plug in 5 for the time in years; y= the value of y in terms of the x-value, so when x is 5, y is 45,000
4) you end up with something like this
45,000= 18,000b^5
5) in order to proceed to solve you must get b alone
6) divide both sides by 18,000
7) so you no have 2.5= b^5
8) take the fifth root of both sides
9) now you have your answer b=<span>1.20112443398</span>
This is not much of a question, because it doesn't take into account the width of the wood trim.
So you are asked to find the perimeter of the window, ignoring the width of the trim.
P = Perimeter = 2L + 2W.
Here, P= 2(9 1/3 feet) + 2(6 3/4 feet) = 2(28/3 feet) + 2(27/4 feet)
So P = 2[28/3 + 27/4] feet. LCD is 3*4 = 12.
Thus, P = 2 [ 28/3 + 27/4 ] feet. Can you finish? Add together the fractions 28/3 and 27/4.
