96.5 times 2.54
the answer is 245.11
Answer:
See below
Step-by-step explanation:
5x + y = 9 re-arrange to y = 9-5x
use this value of 'y' in the second equation:
10x - 7(9-5x) = - 18
solve for x = 1
sub in this value of 'x' into one of the equations to compute 'y'
5 (1) + y = 9
y = 4
Answer:
when opening the bracket remember that the value outside the bracket will be used to multiply the value inside the bracket
The distance formula is d=\sqrt{(x_{2}, x_{1})^{2} +(y_{2}, y_{1})^2
7=x1
4=y2
-8=x2
4=y2
Just plug in the missing values into the equation and solve the equation :)
