1/4 = 0.25
2/3 = 0.666666667
0.25(0.666666667) = 0.166666667 =

Answer:
x = 4
, y = −
2
Step-by-step explanation:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
Answer:
p=2
Step-by-step explanation:
−4p=11−19
−4p=−8
then you divide both sides by -4 and two negatives make a positive.
(2.5 x 10^-8)(9 x 10^-10) = (2.5 x 9) x (10^(-8 + (-10))) = 22.5 x
10^(-8 - 10) = 2.25 x 10^1 x 10^-18 = 2.25 x 10^(1 + (-18)) = 2.25 x
10^(1 - 18) = 2.25 x 10^-17
