Answer:
16 - c
Step-by-step explanation:
Becasue she is losing the money so subtraction but the 16 will be first
withdrew 1200
spent 1/5 on travel : 1/5(1200) = 1200/5 = 240
leaving her with : 1200 - 240 = 960
spent 2/3 on hardware : 2/3(960) = 1920/3 = 640
leaving her with : 960 - 640 = 320
320 - lunch = 300.50
320 - 300.50 = lunch
19.50 = lunch <==
Answer:
you can't factor that.
Step-by-step explanation:
whenever we end up with an expression on the left-hand-side that is equal to the equation on the right-hand-side, is a way of saying, the system of equations, contains two lines that are exactly the same thing, but one is in disguise, something like say
9x + 15 = (3x + 5)3
now, if we distribute the 3 on the right-hand-side, we'd end up with the same equaton on the left-hand-side, so both are the same.
graphing wise, a solution is where both graphs intersect, when two equations are equal they'll intersect, well, at every single point, since their graph is really just one graph pancaked on top of the other, since they touch each other at every point, infinitely many solutions.
