X^2 and 5x both have x in common to factor out. To add or subtract them, 5x^2 is the least common denominator .
Answer:
For #2: It's C. 17 nickels and 15 quarters.
Step-by-step explanation:
17*5= 85
15*25= 375
375+85= 460
add in the decimal:
17* 5 cents= $.85
15* 25 cents= $3.75
$3.75+ $.85= $4.60
This is really up to you. Also you Didn’t provide the assignment so this is impossible to answer, I can put anything in there. Just think about what you did and answer the questions yourself.
Answer:
210
Step-by-step explanation:
For getting this answer we need to find the minimum common multiplier, this is, the smaller number that is multiple of all 5, 6 and 7.
For example, 30 is multiple of both 5 and 6, son in 30 days two suppliers will come, but not the third, as 30 is not a multiple of 7.
Let's try with the next multiple of 5 and 6, this is 60, but is not a multiple of 7.
The next is 90, but again not multiple of 7. Niether are the next: 120, 150, 180.
But when we arrive to 210 we see that, as we are going from multiples of 5 and 6, and 210/7=30, 210 is also multiple of 7.
So, the answer is 210.
95% of 600 is 570. When solving a percentage problem like this, simply convert the percentage into decimal form (.95) and that multiply that by the main number (600).
