These triangles are congruent by
the triangle
congruence
postulate [? ].
A. SSS
B. SAS
C. Neither, they are not congruent

B. SAS

Step-by-step explanation:

There is already a pair of corresponding congruent sides and angles. To continue, the side length in between is shared, so automatically, that is also a congruent side to both triangles. That is because of the reflexive property. So now, in the order that the corresponding congruent sides and angles appear in, the answer is SAS.

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
