If the two triangles are congruent it means that their side lengths are equal, so we can assume that x = 3x - 8 and so 2x = 8 and x = 4. Hope that helps :)
The answer should be x=4/3
Answer:
11 times
Step-by-step explanation:
65-10=55

Step-by-step explanation:
1. add the numbers all together
(of the pets)
= 40 pets total
40 pets =100%
1 pet = 2.5%
percents:
Cat= 10, or 25%
Dog = 15, or 37.5 %
fish=8 or 20%
bird= 7 or 17.5%
angles:
dog= 135
cat= 90
fish= 72
bird= 63
Answer:
The commutative property of addition says that changing the order of addends does not change the sum.
(a+b)+c = a+ (b+c)
( -8 + -7) + 6 = -8 + ( -7 + 6)
-15 + 6 = -8 + -1
-9 = -9
