82.5 i believe because the radius is half of the diameter.
2x+23=92
Move +23 to the other side.
Sign changes from +23 to -23.
2x+23-23=92-23
2x=92-23
2x=69
divide both sides by 2 to get x by itself
2x/2=69/2
Cross out 2 and 2, divide by 2 and then becomes 1*1*x=x
Answer:
x=69/2 and x=34.5 and x=34 1/2
Answer:
5. 2√6
6. 4
Step-by-step explanation:
5. x =√[3×(3+5] = √3×8 =√24=2√6
6. x(x+5)=6²
x²+5x=36
x²+5x-36=0
(x+9)(x-4) =0
x=-9 or x=4
Answer:
3t - 16
Step-by-step explanation:
