-9 is a negative number, so plus 25, it would be 16. The minus sign and the negative sign of -10 cancel out, so it is plus 10, ending up with 26. Finally, the + and - becomes negative (positive times negative equals negative), so it is -6 and you’ll end up with a final answer of 20.
Answer:
C
Step-by-step explanation:
-4+9=5
$135 + $15x is greater than or equal to $300
Alright, so the money you make is automatically -1500 for the tools, so it's -1500. Next, the materials cost 200 dollars for each scooter, s, so we have -1500-200s. After that, we have 300 dollars for the sale of each scooter, so we have -1500-200s+300s. Adding -200 and 300 together, we have -1500+100s. To make a profit, that means 100s -1500 > 0. Dividing by 100, we have
s -15 >0 and s>15, so if you sold 16 scooters you'd make a profit. That profit would be 100*16-1500=1600-1500=100 dollars
Answer:
4x-5, x= 5/4
Step-by-step explanation:
Basically factor the top part and see if you cancel bottom!
16x^2 -25 , you'll realize it's a difference of squares,
Hence, factored form would be like this:
(4x+5)(4x-5)
Hence, (4x+5) cancels out and your answer is 4x-5
x= 5/4
