Answer:
-1/2
Step-by-step explanation:
Teacher went through it with us in class.
Answer:
Step-by-step explanation:
What we know is that A + S = 111. That is, the miles Andre drove plus the miles Scott drove totalled 111 miles. What we also know is that Scott drove quite a bit more than Andre did. Scott drove 7 miles more that ( +7 ) 3 times the number of miles Andrea drove. That looks like this algebraically:
S = 3A + 7
Now we can sub in that value for S to the original equation:
If A + S = 111 and S = 3A + 7, then
A + 3A + 7 = 111 and
4A + 7 = 111 and
4A = 104 so
A = 26 and
S = 3(26) + 7 so
S = 85 miles.
Scott drove 85 miles.
It would be 910,000 because your rounding up.
Answer:
3(x+y)
Step-by-step explanation:
3(x+y)
distribute
3x+3y
Answer:
Step-by-step explanation:
y=mx+b where m=slope and b=y intercept
m=(y2-y1)/(x2-x1), we have points (0,0) and (4,12)
m=(12-0)/(4-0)=12/4=3
y=3x+b, using point (4,12) we can solve for b
12=3(4)+b
12=12+b
b=0 so the line is
y=3x
