Step-by-step explanation:
Given
3 (t + 4 ) = 25.5
t + 4 = 25.5 / 3
t + 4 = 8.5
t = 8.5 - 4
t = 4.5
Hope it helps :)
I would go with option C. x, in the first equation.
The X term has a coefficient of 3, the lowest common factor amongst the 3 terms making for easy isolation of the variable.
Answer:
A, (4,-3), (1, -1), (7,-6)
Step-by-step explanation:
f(x, y) = (y, -x) there is a 90° clockwise or 270° counterclockwise rotation
Answer:
x = 20/9
Step-by-step explanation:
We want to write out all of the mixed fractions into improper fraction form. So -2 and 1/9 becomes -19/9 and -4 and 1/3 becomes -13/3. Then we get (-19/9) - (-13/3). The two minus signs together means a positive/plus sign, so we get -19/9 + 13/3. In order to add, we want the denominator to be the same. A common denominator could be 9, so -19/9 + 13(3)/3(3) = -19/9 + 39/9 = 20/9, which is our final answer
I think the answer is 716.7 not 100% positive
