Answer:
4y+5 vegetable seeds.
Step-by-step explanation:
In order to find the total amount of vegetable seeds, you need to add y+3y+5.
You have to combine your like terms.
3y and y are like terms, so you add them to get 4y. 5 and 4y are not like terms, so you just write your expression as 4y+5.
Hope this helps!
Answer:
y = 2/3x + 3
Step-by-step explanation:
y - 5 = 2/3(x - 3)
y - 5 = 2/3x - 2
y = 2/3x - 2 + 5
y = 2/3x + 3
Answer:
The weight of Paula's dog is 36 pounds.
Step-by-step explanation:
SO we would draw one box for the weight of Carla's dog. Then we would draw 3 boxes for the weight of Paula's dog.
To find how much does Paula's dog weigh we divide the total weight of the dogs by the total number of boxes.
So then you would calculate 48 divided by 4.
The weight of Carla's dog is 12 pounds.
Therefore the weight of Paula's dog is 3x12=3x10+3x2=30+6=36 pounds.
In general, nCr = n! / r! (n-r)!
Here, 7C3 = 7! / 3!(7-3)!
=7 x 6 x 5 x 4 x 3 x 2 x 1 /3 x 2 x 1 ( 4 x 3 x 2 x 1)
=7x6x5x4 / 4x3x2
=7x5x6x4 / 24
=35x24 / 24
=35
