Answer:
6 days
Step-by-step explanation:
pay 60 = -60
Let d = the number of days
30d - 60 = sister
20d = me
Equation:
30d - 60 = 20d Move 30 to the other side
-30d -30d
-60 = 20d - 30d Combine liked terms
-60 = -10d
-10 -10 Divide
d = 6
Answer:
il faut passer les x de l'autre voter comme x=9+5=14 donc x=14 je pense que c'est ça mais je suis pas sûr et tu fait pareil pour l'autre
33 because the fracture of it is equaling that just get a calculator and divide them by the 12 for each one and you we’ll see
explanation:
Change both equations into slope-intercept form.
5x + 4y = 1
4y = 1 - 5x
y = 1/4 - 5/4x
y = -5/4x + 1/4
4x + 5y = 3
5y = 3 - 4y
y = 3/5 - 4/5y
y = -4/5y + 3/5
The lines are not perpendicular because the slope of the second line is not the opposite of the original line.
Best of Luck!
