Answer:
t = 74 / 9
Step-by-step explanation:
-9(t - 2) = 4(1 - 15)
-9t + 18 = 4 - 60
-9t + 18 = -56
-18 -18
-9t = -74
/-9 /-9
t = 74 / 9
t = 8.22
The answer to the question is b
Answer:
Is this a problem? ( Math )
Step-by-step explanation:
First, we write the first equation where the left side contains x and y in the right side. We do as follows:
x = 2y + 6
You, then substitute the equation to the second one.
3(2y + 6) + y = 8
6y + 18 + y = 8
7y = -10
y = -10/7
x = 22/7
Answer:
(√77) / 22
Step-by-step explanation:
