1,0,1,2 is the correct answer I do believe
Answer:
22
Step-by-step explanation:
7(7a-9)>84
first multiple out to get rid of the parentheses
49a - 63 > 84
add 63 to both sides
49a > 147
Divide by 49 and flip the sign because when you divide a inequality you have to flip the sign
a < 3
Add 4 to the right side of the equation to get sex then divide that by 2X and you get 3
Answer: 7.5 miles
Step-by-step explanation:
think of it as a triangle; the bold line is the hypotenuse, or x.
8 |\ x
|_\ it's not a good triangle but you get the point
6
and then get out pythagorean theorem: a^2+b^2=c^2
put the numbers in: 8^2 + 6^2 = x^2
do some math:
64+36=x^2
100=x^2 (and then find square root)
10=x
<u>BUT</u>, it said each unit was 3/4 of a mile, so we must multiply 10 by 3/4 to get the actual distance, which is 7.5
