Answer:
10 minutes
Step-by-step explanation:
Since you can do 6 flyers each minute, the rate would go at 6x, with x being minutes. You initially did 80, so the equation for you would be y=6x+80.
Your friend's equation would be y=4x+100, because he initially had 100 done and is now getting 4 done per minute.
If you put the 2 equations in your calculator, the intersection will happen at x=10, showing that you and your friend will have an equal number of flyers at 10 minutes.
Answer:
7
Step-by-step explanation:
12b -b = 11b
11b = 77
Divide both sides by 11
b = 7
Step-by-step explanation:
1) 2x+3y-3y=1-3y. -x+2y= -4
2x/2=1-3y/2. -(1-3y/2)=-4
x=1-3y/2. -1+3y/2= -4
x=1-3(-2)/2 3y/2= -4+1
x=1+6/2 3y/2×2/3= -3×2/3
x=7/2 y= -2
S.s{ 7/3,-2}
2). -4x-6y+6y=7-6y. 4x+y= -2
-4x/-4=7-6y/-4. 4(-7-6y/4)+y= -2
x= -7-6y/4. -7-6y+y = -2
x= -7-6/4 -5y/5= 5/5
x=-13/4 y= 1
S.s { -13/4, 1 }
