Answer:132
Step-by-step explanation: 1.25-.50=75 the profit of each apple is 75 cents
99 dollars divided by .75 is 132
5x + 10y = 18
x = y -6, we substitute this into first equation.
5x + 10y = 18
5*(y - 6) + 10y = 18
5y - 30 + 10y = 18
So it the last option from the top.
Answer:
80/2, 120/3, 160/4, 200/5, 240/6, 280/7, 320/8, 360/9, 400/10, 440/11, 480/12, 520/13, 560/14 , 600/15, 640/16, 680/17, 720/18, 760/19, 800/20, 840/21
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
The slope of a line is
m = (y2-y1)/(x2-x1)
= (-2 -4)/(-1 - -4)
= -6/ ( -1 +4)
= -6 /3
=-2
The solution on the graph is (x,y)=(7,25), so x=7.
x=7 in the equation a, so the answer is
A.
