Answer:
Mr Jackson should get $8.88 back.
Step-by-step explanation:
$50 - $41.12 = $8.88
Answer:
a) (-1,4.5)
b)10.63 units
c)7/8
Step-by-step explanation:
a) To find this, we use the midpoint formula
(x,y) = (x1 + x2)/2 , (y1 + y2)/2
(x1,y1) = (3,8)
(x2,y2) = (-5,1)
(x,y) = (3 -5)/2 , (8 + 1)/2 = (-1, 4.5)
b) To calculate the distance D between two points, we use the formula;
D = √(x2-x1)^2 + (y2-y1)^2
D = √(-5-3)^2 + (1-8)^2
D = √(-8)^2 + (-7)^2
D = √64 + 49
D = √113
D = 10.63 units
C) We use the slope formula here
m = (y2-y1)/(x2-x1)
m = (1-8)/(-5-3) = -7/-8 = 7/8
Answer:
It is 33. Answer B is correct.
Answer:
RS = 20
ST = 40
Step-by-step explanation:
R____S____T
RS + ST = RT
3x - 16 + 4x - 8 = 60
3x + 4x - 16 - 8 = 60
7x - 24 = 60
+24 +24
--------------------------------
7x = 84
/7 /7
---------------------------------
x = 12
Let's use what we got for x to find the length of ST and RS
ST = 4x - 8
= 4(12) - 8
= 48 - 8
ST = 40
RS = 3x - 16
= 3(12) - 16
= 36 - 16
RS = 20
so, RS = 20, ST = 40, and RT = 60
First you subtract 15 from 26 and get 11.
Second you multiply 11 by 2 and get 22.
Therefore your answer is 22.
