Answer:
The wording seems a bit off, I usually see it as deductive reasoning but yes, you take what you know and use that to "deduce", or find out something
If you plug in the respective numbers (x,y) you'll get the answer choice C. 19=4(4)+3 : 19=19
The lines are proven to be parallel so that executes the two perpendicular choices, so I'm assuming it is 'The lines are parallel because the slopes are the same'...
Answer:
16 km
Step-by-step explanation:
Given:
Distance from Washington to Stamford = distance from Washington to Salem + distance from Salem to Stamford = 10.3 km + 11.9 km = 22.2 km
Distance from Washington to Oakdele = 6.2 km
Required: the difference between the distance from Washington to Stamford and from Washington to Oakdele
Solution:
Distance from Washington to Stamford = 22.2 km
Distance from Washington to Oakdele = 6.2 km
The difference = 22.2 km - 6.2 km = 16 km
Therefore, from Washington, it is 16 km farther to Stamford than to Oakdele.
Teds minimum grade he needs on his third test is 65
85 + 60 + 65 = 210
210 divide by three (as there are three tests) = 70
