Nomber15:851-215=636

15. Since p=215. 851-p would be 851-215 which equals 636

18. Since a=6 and b=5 and c=3, ab/2 would be 6x5/2 which equals to 30/2. Now, you must add 30/2 to 4c. And again since c=3, it would be 4x3 which equals to 12. So now the equation would be 30/2+12. You must now turn the fraction into a whole number by 30÷2 which is 15. The question would now ask 15+12 so the answer would be 27

aleena has a watering can. she uses 3/8 gallonto water her roses and1/3 gallon to water the geraniums . How much water did. Alee
WINSTONCH [101]
The answer is simple to work out you  do 3/8 + 1/3

but the denominators are different so you find the lowest common multiple in this case 24 .
the frection is now 9/24 + 8/24 this is 17/24
I changed the fraction by doing this 24(common multiple) divided by 8 (denominator) that's how I got it if you don't understand just ask me

WINSTONCH [101]

Answer:

32 people

Step-by-step explanation:

If 3/4 equals 24, we need to find the other fourth. We can divided the total number of people by the numerator. 24/8, then add 8, which equals 32.

8w-15=57 two step equations
insens350 [35]

Answer:

w=9

Step-by-step explanation:

Our equation is: 8w-15=57

Add 15 to both sides

-15 is now gone because we added 15 so it would be zero

and we have 72 because 15 plus 57 is 72

Now we have:

8w=72

Divide by 8 on both sides

8w cancels out to just w

and 72 divided by 8 is 9

And you're left with:

w=9
