Look at that website. The part says that (ab*ad)=(ac*ae)
Doing that, we get
9*(9+11x)=10(10+8x)
81+99x=100+80x
19x=19
X=1
Answer:
63 m
Step-by-step explanation:
We know the rate in 45 m / min
We need to change the time to min
1 min 24 sec
We know that 1 min = 60 sec so 24 seconds is 24/60 ths of a minute
1 min 24/60 min
1 2/5 min
Changing to decimal form
1.4 minutes
Now we multiply by the rate to get the distance
d = r *t
d = 45 m/ min * 1.4 min
d= 63 m
Answer:
15
Step-by-step explanation:
Answer x=1/5
6x-3=-9x
-3=-15x
-3/-15x=1/5
