Answer:
this is the graph to the equation :) hope this helps in all ways possible:)
Step-by-step explanation:
The answer would be 15 but i am not sure what the problem says her answer is. if it is not 15 then her answer is wrong
112 dallors interest beca0.02x + 0.04(800) = 112 0.02x + 0.04(x + 800) = 112 0.04x + 0.02(x + 800) = 112 use
83.3
Just add up all the numbers and divide by 6, as there are six numbers in this set of numbers
-3w= -7w-7 =
-3w+7w = -7w+7w - 7 =
4w= -7
4w/4 = -7/4 =
w = -7/4
