20=5t because you subtract 3t from 8t and you get 5t. then you add 14 to 6 and get 20. so you get 20=5t
4x + 3y = 5
4x - 4x + 3y = -4x + 5
3y = -4x + 5
3 3
y = -1¹/₃x + 1²/₃
y - y₁ = m(x - x₁)
y - (-1) = ³/₄(x - (-6))
y + 1 = ³/₄(x + 6)
y + 1 = ³/₄(x) + ³/₄(6)
y + 1 = ³/₄x + 4¹/₂
- 1 - 1
y = ³/₄x + 3¹/₂
7/12.
If you make 1/3, 5/12, and 1/2 the same denominator, it will be:
4/12,5/12,and 6/12.
you can see that these fractions are increasing 1/12 for each day. so on the forth day, it will be 7/12.
9+2j=-9-j
+j
9+3j=-9
-9 -9
3j=-18
/3j /3j
j=-6
but in words that would be 9+2j=-9-j plus the j over to the 2j that becomes 3j then minus the 9 over and you get -18 so now you you have 3j=-18 divide by 3 and you get -6
