Answer:
u = -3
Step-by-step explanation:
Solve for u:
u - 5 = -8
Hint: | Isolate terms with u to the left hand side.
Add 5 to both sides:
u + (5 - 5) = 5 - 8
Hint: | Look for the difference of two identical terms.
5 - 5 = 0:
u = 5 - 8
Hint: | Evaluate 5 - 8.
5 - 8 = -3:
Answer: u = -3

C. The total amount spent on drinks by Andrew.

Answer:
x=8
A = 192
Step-by-step explanation:
The perimeter is the sum of the outer lengths
17.9 + 22.6 + 3x = 64.5
Combine like terms
40.5 +3x = 64.5
Subtract 40.5 from each side
40.5 +3x -40.5 = 64.5 - 40.5
3x =24
Divide each side by 3
3x/3 = 24/3
x = 8
The area of a triangle is given by
A = 1/2 bh
The base is 3x = 3(8) =24
and the height is 2x = 2(8) =16
A = 1/2 (24) * 16
A =192
