She has 4 groups all together. 3 groups with ten rocks each and 1 group with 8 rocks(8/10).
Step one rewrite: -46-8x>22
Add 46 to both sides: -8x>68
Divide both sides by -8 to isolate x<-8.5
(remember to flip the inequality sign when multiplying or dividing by negative numbers in inequality problems)
So the correct answer is B. x < -8.5
Answer:
C. HL
Step-by-step explanation:
The two triangles shown are right triangles.
The hypotenuse of one is congruent to the hypotenuse of the other. Also, the length of one of the legs of one triangle is congruent to the corresponding leg of the other triangle.
Based on true HL Congruence theorem, both triangles are congruent to each other.
Therefore, the congruence correspondence that will prove both triangles are congruent is: HL
Answer:
k+1/2 =4
subtract 1/2 from both sides
= k = 3.5 or 3 1/2
