Number 4 please. its confusing
Deffense [45]

Answer:

63 monocotyledons

Step-by-step explanation:

some abbreviations ill be using:

monocotyledons=m

dicotyledons=d

3m / 4d

x / 84d

you need to figure out what x is

you can divide 84/4 and get 21

now that you have 21, you can multiple that number by 3

21x3=63

therefore, there are 63 monocotyledons

I need help with this question​
Artyom0805 [142]

Answer:

Step-by-step explanation:

It's algebra really, basically make a system of equations.

1b+5j=t

3b+2j=2t

I'm gonna solve the first one for buckets so we have it in terms of jars.

b+5j=t

b=t-5j

Now I plug that into the other equation

3b+2j=2t

3(t-5j)+2j=2t

3t-15j+2j=2t

Now, since it wants how many jars are in one tub, I want to solve it so there's 1t on one side of the equation and all js on the other.  or it other words solve for t.

3t-15j+2j=2t

3t-13j = 2t

3t = 2t+13j

t = 13j

So it takes 13 jars to make one tub, or one jar is 1/13 of a tub.  You could then plug that in to one of the equations and find how much a  bucket is.
