10 + f = 10
-10 -10
f = 10 - 10
f = 0.
Answer: 4x^2 -13x + 14
Step-by-step explanation:
(x^2 - 8x + 5)-(-3x^2 + 5x-9)
Subtract -3x^2 from x^2
(4x^2 - 8x + 5)-(5x-9)
Subtract 5x from -8x
(4x^2 -13x + 5)-(-9)
Subtract 9 from 5
4x^2 -13x + 14
Answer:
125 seconds
Step-by-step explanation:
We can solve this problem with the help of two methods
We can set up this question as a ratio problem:
360 meters__________15 seconds
3000 meters_________x seconds
We can also solve it as a rate problem and still yield the same answer:
x=125
24% of 80
24/100 = 0.24
0.24 * 80 = 19.2
answer should be 19.20
