well, let's say 1 meter is the 100%, now, if we know that 1 is 100%, what percentage is 70?

Answer:
No it doesnt because 6 does not equal 2
Factor the expression.
3(128j+3)
This can be solve by first solving the proportionality constant
Number electic outlets rewired is directly proportional to
time spent
4 = (1 ½)a
Let be the proportionality constant
A = 8/3
O = (8/3)(7.5)
o = 20 outlets will jamal rewired if he works for 7.5 hrs
