Answer:
(x, y) = (-11, 4)
Step-by-step explanation:
You can subtract 3 times the second equation from the first to eliminate y.
(7x +9y) -3(x +3y) = (-41) -3(1)
4x = -44
x = -11
Substituting into the second equation gives ...
-11 +3y = 1
3y = 12
y = 4
The solution is (x, y) = (-11, 4).
Answer:
It will take 4 seconds.
Step-by-step explanation:
It takes the puppy 25 seconds and the cat 20 seconds.
20+25=45
180 divided by 45 = 4
= 4 seconds.
Total = 100.00 * (1 + .06/12)^12*20
Total = 100.00 * (1.005)^240
Total = 100.00 *
