Answer:
2x +2y -8
Step-by-step explanation:
If the equal sides are 'a' and the third side is 'b', then the perimeter is ...
P = a +a +b = 2a +b
The length of the third side is then ...
b = P -2a . . . . . . subtract 2a from both sides
Substituting the given expressions, we find ...
b = (10x +4y -18) -2(4x +y -5)
b = 10x +4y -18 -8x -2y +10
b = 2x +2y -8 . . . . the length of the third side

Answer:
A. car needing both repairs is the intersection, which is P(A) * P(B).
92/200 * 136/200 = 391/1250 = .3128
B. car needing an alternator and not needing new brakes is the union, which is P(A) + P(notB) - P(A and B). We solved for P(A and B) in part A.
P(A) + P(notB) - P(A and B)
136/200 + 108/200 - .3128 = .9072
Answer:
18
Step-by-step explanation:
x-5=(x+8)/2
x-5=x/2+4
add 5
x=x/2+9
subtract x/2
x/2=9
times 2
x=18
