Answer: D: Corresponding parts of congruent triangles are congruent
Step-by-step explanation:
If two triangle are congruent using postulate of theorems of congruence then their corresponding parts are congruent by CPCTC rule.
The CPCTC rule says that if two triangles are congruent then their each corresponding part whether angles or sides must be equal.
Here if triangle abc= def by side-side-side triangle congruence theorem,
then b=e [which is a corresponding part of both triangles] by Corresponding parts of congruent triangles are congruent.
1.5 hours=90 minutes
Because 90 minutes/ 30 minutes is 3, multiply 3.6 miles by 3 and get 10.8 miles as your final answer
Answer:

Answer:
a) x = -10
b) x = 7
Step-by-step explanation:
a)
2(x + 3) = x - 4
2x + 6 = x - 4
2x - x = -4 - 6
x = -10
b)
4(5x - 2) = 2(9x + 3)
20x - 8 = 18x + 6
20x - 18x = 6 + 8
2x = 14
x = 7
