The answer is 9.5. Hope that helps!
3(2t+5)=5t+25
Multiply the bracket with 3
(3)(2t)(3)(5)=5t+25
6t+15=5t+25
Move 5t to the other side. Sign changes from +5t to -5t
6t-5t+15=5t-5t+25
6t-5t+15=25
Move +15 to the other side. Sign changes from +15 to -15
6t-5t+15-15=25-15
6t-5t=10
1t=10
divide by 1
1/1t=10/t
t=10
Answer: t=10
Break it off where the triangle goes into a square/ rectangle
<h2>Answer</h2>
Or as ordered pairs:
<h2>Explanation</h2>
Lets solve our system of equations step by step
equation (1)
equation (2)
1. Solve for in equation (2)
equation (3)
2. Replace equation (3) in equation (1) and solve for
or
3. Replace the values of in equation (3) and solve for
- For
or
- For
or
So, the solutions of our system of equation are:
I believe the second one right, because if I remember two opposite angles of an outside angle = the outside angle.
