Answer:
AB = 3
Step-by-step explanation:
Since AB is a perpendicular bisector then Δ is isosceles and AD = AC, that is
4x - 1 = 2x + 3 ( subtract 2x from both sides )
2x - 1 = 3 ( add 1 to both sides )
2x = 4 ( divide both sides by 2 )
x = 2
Hence AB = x + 1 = 2 + 1 = 3
Answer:
the difference between the two fractions is 1/10
Step-by-step explanation:
when solving this problem you must switch the denominators to the same number. in this case thats 30. so 10*3 is 30 and 15*2 is 30. so then we multiply 7*3 to get 21 and 14*2 to get 24. so now we have 21/30 and 24/30, so then we compare. and we end up with 3/30, we simplify the answer to 1/10.
Answer:
1
Step-by-step explanation:
The range is the difference between the largest and smallest values.
range = 9 - 2 = 7
If 2 is replaced by 3 then 3 becomes the smallest value and
range = 9 - 3 = 6
That is the range decreases by 1
Answer:
150 miles
Step-by-step explanation:
We can split 3 hours into six sections of 30 minutes, then multiply those six sections by the 25 miles. 6 times 25 equals 150
