Answer:
THE FIRST OPTION
Step-by-step explanation:
X=12 because 73-3x=61-2x so add 3x to both to make 73=61+X then subtract 61 from both to get 12=X
Answer:
1200 ml per hour
Step-by-step explanation:
To compute what rate is 300 ml over 15 mins as a rate of ml per hour, we do a rule of 3, using a variable x as that amount of ml we don't know yet. We should have everything in the same units, so instead of writing 1 hour we write 60 minutes:
Now we solve for x:
And so, now that we know the value of x, the rate we wanted to find is
Which is just 1200 ml per hour.
Answer:
70 miles
Step-by-step explanation:
128-65/.9=m
128-65=63

70<or equal to m
Answer:
A. 2x + 1
Step-by-step explanation:
6x³ - 15x² - 9x
3x (2x² - 5x - 3)
3x (2x² + x - 6x - 3)
3x (x (2x + 1) - 6x - 3)
3x (x (2x + 1) - 3 (2x + 1))
= 3x <u>(</u><u>2</u><u>x</u><u> </u><u>+</u><u> </u><u>1</u><u>)</u> (x - 3)
one of the factor of the complete factorization is <u>A</u><u>.</u><u> </u><u>2</u><u>x</u><u> </u><u>+</u><u> </u><u>1</u>
