Answer:b and c
Step-by-step explanation:
First you have to find a common denominator which is 8.
1/2 =4/8
7/8 - 4/8 = 3/8
So the answer is 3/8.
Answer:
The smallest value of the three numbers would be 9.
Step-by-step explanation:
In order to find this, set the smallest number as x. Then you can set each of the next integers as x + 1 and x + 2. Now we can total all three numbers and set equal to 30 to solve for x.
x + x + 1 + x + 2 = 30
3x + 3 = 30
3x = 27
x = 9
0.18 miles per hour or mph
It seems you tried to write √(-20)
use the fact tha -1 = i^2
Then, √(-20) = √(20i^2) =(√20) i = (√(5*4))i = 2√5 i = 2i√5, which seems to be what you tried to write in the option B.
