Answer: t = 77
Step-by-step explanation:
To solve for t, we will simplify and isolate the variable.
Given:
65 = t - 5 - 7
Combine like terms:
65 = t - 12
Add 12 to both sides of the equation:
77 = t

Answer:
x = 11√2
Step-by-step explanation:
We can notice the triangle given is a special triangle, a 45°- 45°- 90° triangle. The hypotenuse of a 45°- 45°- 90° is √2 times the length of a side. We can set up the equation(using x as the side):
x * √2 = 22
We can divide by √2 on both sides to get:
x = 22 / √2
To rationalize the denominator, we multiply by √2 / √2 on the right side:
x = 22√2 / 2
This simplifies to:
x = 11√2
Answer:
x=20
Step-by-step explanation:
10x-60=140
10x=140+60
10x=200
x=20
I think what you need to do is make B = -5
3a = -2(-5) - 7
3a = 10 - 7
3a = 3
a = 1
