Answer:
Step-by-step explanation:
Okay this is an odd question, but what i'm thinking is that
first you have
5x+5
To actually be able to solve we have to move the 5 to the other side.
To do this we subtract it.
Making the equation
5x = -5
Then you need to isolate the variable (X)
So divide 5X by 5, and then divide -5/5
Which leaves you with:
x=-1
Answer:
65 miles
Step-by-step explanation:
There are two simultaneous equations
. Remeber that v=d/t, 1hour = 60 minutes.
1. 40 = (d+15)/(t+0.5)
2. 50 = d/t
solving: d= 25 miles and t=0.5 hours.
The distance traveled is:
D=d+d+15
D=65 miles
the answer will be 20 times 3 that is 60
Answer:
(1, 5), (3, 19) (-1, -9)

Answer:
B 12
Step-by-step explanation:
- manuel ate 1/3X
- His brother ate 1/4X
- leftover is 5
- total is X
manuel+brother+leftover=X
x/3+x/4+5=x
7x+60/12=x
7x+60=12x
60=12x-7x
60=5x
x=60/5
x= 12
