T1 + d = 9/2
t5 = t1 + 4d = 6
Now we have two simultaneous equations:
t1 + 4d = 6 ............(1)
t1 + d = 9/2 ...........(2)
Subtracting (2) from (1) gives:
3d = 3/2
So the common difference d = 1/2
and by substitution in (1) we find t1 = 4
Therefore the 3rd term = 4 + (2 * 1/2) = 5
Answer:
$210
Step-by-step explanation:
A week is 7 days, if the doctor makes 30 dollars a day it would be 30x7 which = 210
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)
Answer:
p because variables are shown by letters not numbers

Step-by-step explanation:
Answer: 51.5 inches
Step-by-step explanation: The high jumper will be making seven jumps, increasing by 1/2 inch each time. In order to calculate how much it will be moved up from the original position we need to multiply 1/2 x 7 jumps = 3.5 inches. In order to calculate how high the bar will now be, we need to add together the original 48 inch height plus the 3.5 inches that it was been raised, so they total is 51.5 inches high.
