First you add 3d to d so you gonna have 4d and after that you can add 7 on both sides so you gonna have : 4d = 25/4 + 7 ⇒ 4d = 25/4 + 28/4 ⇒ 4d = 53/4 now you can multiply the both sides by 1/4 so you gonna have : d = 53/16 ⇒ d = 3.31 :))
i hope this is helpful 
have a nice day

3d + d -7 = 25/4

4d - 7 = 25/4  (combined like terms)

4d - 7 + 7 = 25/4 + 7 (add 7 to both sides)

4d = 53/4

d = 53/4  ÷ 4 (did the inverse operation of d)

d = 53/16   or    d = 3.31

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.
