Answer:
-1/30
Step-by-step explanation:
find the lcm of 10 and 15
then solve it
You can use a proportion.
4 hours is to 82 miles as 14 hours is to x miles
4/82 = 14/x
Cross multiply to get
4x = 14 * 82
4x = 1148
x = 287
287 miles
Answer:
$176
Step-by-step explanation:
$200 x 12%
12% --> 0.12
200 x 0.12 = 24 --> discounted off amount
200 - 24 = 176
Answer:
Step-by-step explanation:
To solve using completing square, we need to write the equation as x2+3x=17.
The next step is to add a number such that the square can be completed. The number must be equal to (b/2a)^2, so here it will be (3/2)^2 = 9/4
The equation then becomes x2+3x+(9/4)=17+(9/4).
Solving it further will get you the final answer
LCD would be 18
8/9 = 16/18
2/3 = 12/18
1/9 = 2/18
