1week = 7days so
4weeks = 28 days
So 28 x 640 = 17920
1000grams = 1kg
17920 divide 1000 =17.92
Lee uses 17.92kg in those 4weeks
To solve for y you have to simplify both sides of the equation, then isolating the variable which equals to...
y = -4x/3 + 4
Next, you have to move all terms that don't contain y to the right side and solve.
y = 10 + 2x/3
____
Now we solve the first variable in one of the equations, then substitute the result into the other equation.
Point Form: (-3,8)
Equation Form: x = -3, y = 8
____
Leaving it to be the only choice which is 'D.) 8', I hope this helps, as always. I wish you the best of luck and I hope you have a nice day..
