Answer:
81 km
Step-by-step explanation:
Speed = distance / time
speed and time are measured in different units, thus, time has to be converted to seconds
60 second = 1 minute
90 x 60 = 5400 seconds
15 m /s = distance / 5400 seconds
distance = 81,000 metre
1000m = 1 km
81000 / 1000 = 81km
Answer:
an estimate is sufficient
Step-by-step explanation:
Assuming the given numbers represent all of the flour Jasper needs, he can estimate that he will need more than 4 cups and less than 4 1/2 cups. It is unlikely that a package of flour will have the exact amount needed, so this estimate is probably sufficient to determine what to buy.
Answer:
y=-3/2x-5
y=x+5
(-4,1)
y=-3/2x+5
y=1/2x
(6,-4)
Step-by-step explanation:
the graph was a bit blurry but I believe this is right
Answer:
x < 4
Step-by-step explanation:
Step 1: Write inequality
2x < 8
Step 2: Divide both sides by 2
x < 4
We see here that any value of <em>x</em> less than 4 will work. So numbers like 1, 0, -124 or even -14687206589174 would work.
