As QS bisects <RQT into 2 congruent triangles
therefore, <RQS = <SQT
4x-25= 2x+5
2x= 30
x= 15
<RQS = 4x-25
= 4(15) -25
=60-25
= 35
I just took the test and the correct answer that i got was B
Answer: 19
Step-by-step explanation:
The answer is 19 because, if n=5 then we have to divide 45 by 5. 45 divided by 5 equals 9. and to make sure we can multiply 9 and 5 and that equals 45. So now its saying what is 9 plus 10 and that equals 19. Just to make sure we can subtract 19 by 10 or 9 and if we do eitheer one they both equal 19.
Hope This Helps!
1 1/2 = 3/2
3/2 ÷3/4 = 3/2 * 4/3 = 12/6 = 2
You should find that your system doesn't have solutions. This is also confirmed by the fact that the determinant of the matrix of the coefficient of the variables x, y and z is equal to zero.
