A=-2 and b=5.
To have an infinite number of solutions, the two sides must be identical.
6x+15=-3(ax-b)
Using the distributive property,
6x+15=-3*ax--3*b
6x+15=-3ax+3b
This means -3ax=6x and 3b=15;
-3ax=6x
Divide both sides by -3:
-3ax/-3 = 6x/-3
ax=-2x
Divide both sides by x:
ax/x=-2x/x
a=-2
3b=15
Divide both sides by 3:
3b/3=15/3
b=5
He would have paid 932.53 by 899.75-20+52.78= 932.53
Answer:
10.1
Step-by-step explanation:
S=d/t, so he goes 45 east than 15 west so he went back, we can do 45-15 which is 30, now we know the distances the person traveled, it took him 15 seconds so know we know the distance and time, to calculate the speed we can do S=d/t, the persons speed is 2 Miles Per hour
