To find the midpoint of a segment you need to use this equation:
(x1+x2/2, y1+y2/2) so if you plug in the numbers its...
9+(-7)/2, 2+(-9)/2
then solve to find x and y coordinate
x= 1 and y= -3.5
so the midpoint of CD is (1,-3.5)
First you know that at 6 it was 75 degrees. Now it’s noon and the temperature is 18 degrees warmer. So when you add 75 and 18 you get 93 degrees. When the storm rolls in at 4 it says that your temperature dropped 21 degrees. So you need to subtract 21 from 93 (93-21) which will get you at 72 degrees at 4pm
The answer is b
If you go backwards on a number line, you are subtracting--which is the same as adding a negative.
First you go backwards 3 numbers, and then to get to -7, you went down (decreased) by 4 more, or subtracted 4 (added a negative 4)
Hello!
To solve this, I would convert to improper fractions. This is done by multiplying the integer with the denominator and adding it to the numerator.
9 3/8: 9*8+3=72+3=75
4 3/8: 4*8+3=32+3=35
So the improper fractions therefore are 75/8 and 35/8.
Now to see what fractions of each other they are, you can just divide the numerators because the denominators cancel each other out.
35/75 = 7/15
So your answer would be 7/15, or B.
Hope this helped!
