Answer: SR ≅ UT
Step-by-step explanation:
Process of elimination:
1) RT ≅ TR doesn't help because RT and TR are the same line.
2) RU ⊥ TU doesn't help prove that ΔRST ≅ ΔTUR. It only proves that ∠TUR is a right angle (which is already given).
3) SR ⊥ ST also doesn't help prove that ΔRST ≅ ΔTUR. It only proves that ∠RST is a right angle (which is already given).
4) The statement that SR ≅ UT tells us that ΔRST and ΔTUR are right triangles and have a hypotenuse and leg in common (both triangles share a hypotenuse, RT, both triangles have a 90 degree angle, and SR ≅ UT). If SR ≅ UT, we can prove ΔRST ≅ ΔTUR by using the HL triangle congruence theorem.
Answer:
the correct answer is 7
Step-by-step explanation:
-5-(-7) = -5 +
two minus is plus so it is
-5 + 7
Let s be the slow train, and s+22 be the faster one. Then:
976/s+s+22=4
976=8s+88
8s=888
s=111 kph as the slower train
s+22=133 kph as the faster train

Answer:
Per slice it cost $0.46
So for 16 slices it will cost 7.36
Answer:
Step-by-step explanation:
We are asked to find the product of 
and 
.
Upon writing our expression as a product we will get,
Let us convert our given mixed fractions to improper fractions.
Upon cancelling out 3 from our given expression we will get,
Upon dividing -7 by 2 we will get,
Therefore, our expression simplifies to -3.5.
