Answer:
x=4
Step-by-step explanation:
2x-3=5
Add 3 to both sides
2x=8
divide both sides by 2
x=4
11w times 6x
240w times 18y
you always use the last numbers and that would equal...
____________________________________________________________
66x times 4320y=
285120 divide it by 6= 47520
then by 12
47520 divided by 12=
3960-80= 3880
3880 divided by 16 times 4
your answer is 970y
A) T(m) = -0.16m +331.3
B) T(2015) = 8.9 . . . seconds
_____
The linear regression function of a graphing calculator can find the equation of the line easily. Or, you can use the 2-point form of the equation of a line.
.. T(m) = (10.5 -14.5)/(2005 -1980)*(m -1980) +14.5
.. T(m) = -0.16(m -1980) +14.5
Please Rewrite you question so it makes sense.
Good Luck :D
