Answer:
9.2
Step-by-step explanation:
a^2 + b^2 = c^2 (pythogoras theorem)
7^2 + 6^2 = 85
Square root of 85 = 9.2 ( nearest tenth)
I think this is right if not srry :(
-10 + a = 6a - 7a
Rearrange the left hand side
a - 10 = 6a - 7a
Simplify 6a - 7a
a - 10 = -a
Add a on both sides
2a - 10 = 0
Add 10 on both sides
2a = 10
Divide by 2 on both sides
a = 5
