Answer:-7/4
Step-by-step explanation:
2(x-2)=6x+2-2(-2x-4)
Open brackets
2x-4=6x+2+4x+8
Collect like terms
-4-2-8=6x+4x-2x
-14=8x
Divide both sides by 8
-14/8=8x/8
-7/4=x
x=-7/4
Answer:
Fran's upstream speed (against the current):
2.9 km/hr - 0.1 km/hr = 2.8 km/hr
Fran's downstream speed (with the current):
2.9 km/hr + 0.1 km/hr = 3.0 km/hr
Using the distance formula for calculating time:
rate x time = distance
time = distance / rate
Fran's upstream time = 9 / 2.8 = 3.21 hrs
Fran's downstream time = 9 / 3.0 = 3.0 hrs
One milion is 1000 thousand or 1,000,000
so million:one is 1,000,000:1
