Answer:
True
Step-by-step explanation:
6x² - 4y - 3x + 6x² + 8x = 12x² + 5x - 4y
Regroup terms on left
6x² + 6x² - 3x + 8x - 4y = 12x² + 5x - 4y
Combine like terms
on left
12x² + 5x - 4y = 12x² + 5x - 4y True
Answer:
3 minutes; 27 minutes; 30 minutes
Step-by-step explanation:
Let the common multiplier of the given ratios be x. So, the ratios 1: 9 : 10 will become x, 9x and 10x respectively.
Therefore,

Thus, 1 hour in the ratio 1 : 9 : 10 can be divided as:
3 minutes; 27 minutes; 30 minutes
You do 65+90=155
then 180-155=25 to get the angle next to w
w=155
Answer
1.56
Step-by-step explanation:
You must find the unit rate. To do so, you must divide 3.90 by 15. That will give you 0.26. After, times 6 and .26 to get your answer. Hope this helps.
3 tens is 3 * 10 = 30
9 ones is 9 * 1 = 9
