The first one is 24, and the second one is 12
I would estimate it as (300 x 7) = 2100
Then I would subtract (11 x 7) + 77 from that to get the exact answer of 2023
~~~~~~~~~~
I didn't use a calculator or paper. The 'trick' is to notice that 289 = (300 - 11)
Answer:
D
Step-by-step explanation:
- ÷ + = -
AND 64/4 IS 16
SOO -16 IS THE CORRECT ANSWER
Answer: D
Step-by-step explanation:
The key to finding the line perpendicular to the one given is teh slope. The slope is the opposite reciprocal of the original line.
m=3
perpendicular m=-1/3
Now that we know the slope, we can see which of our answer choices have -1/3 as the slope. We can see D is the only option that has -1/3 for slope.
