The answer is 16/10 = 40/25
You divided 16 by 40 to see what you need to multiply 16 to get 40. When I did that I got 2.5. So I did that to the 10 and got 25 minutes. Hope this makes sense
Answer:
9
Step-by-step explanation:
7r+18=r²
r²-7r-18=0
factorizing
r²+2r-9r-18=0
r(r+2)-9(r+2=0
(r-9)(r+2)=0
r-9=0
r=9
check
(r²)=(9*9)=81
7r+18=7(9) + 8=81
