Hey!
So the number between needs to be the same number away from 23 and 49. 18 is less than 23 and 49 but we need a number between 23 and 49, so thats a no. same with 72.
Now we are left with 36 and 29.5.
well 29.5 is 6.5 points away from 23 but it is 19.5 points away from 49. So thats a no too because the difference is not the same.
now 36 is 13 away from 23 and also 13 away from 49 and the difference is the same 
So the answer is C!
Hope this helps!

Answer:

HL, LL, SSS, SAS

Step-by-step explanation:

HL is the hypotenuse-leg theorem.  It states that if the hypotenuse and leg of one triangle are congruent to the hypotenuse and corresponding leg of another triangle, the triangles are congruent.  We have that both legs of the triangles are congruent as well as the hypotenuse, so the HL theorem applies.

LL is the leg-leg theorem.  It states that if both legs of one right triangle are congruent to both legs of the second triangle, the triangles are congruent.  We have that both legs are congruent; this is the LL theorem.

SSS is the side-side-side theorem.  It states that if all three sides of one triangle are congruent to the three sides of another triangle, then the triangles are congruent.  All three sides of both triangles are congruent, so this is the SSS theorem.

SAS is the side-angle-side theorem.  It states that if two sides and an included angle of one triangle are congruent to the corresponding two sides and included angle of another triangle, then the triangles are congruent.  We have JL≅QS, ∠L≅∠S and LK≅SR.  This is the SAS theorem.

-7x-6y=-1
Xelga [282]
Cancel something
we cancel x's

multiply 1st equation by 5 and 2nd by 7 and add them
-35x-30y=-5
<u>35x-28y=7 +</u>
0x-58y=2

-58y=2
divide both sides by -58
y=-1/29
sub back
5x-4(-1/29)=1
5x+4/29=1
minus 4/29 from both sides
note, 1=29/29
5x=25/29
divide bot sides by 5 (or times 1/5)
x=5/29


(5/29,-1/29)
