Answer:
For 13: 13/30
Step-by-step explanation:
First simplify!
9x - 25 + 21x - 35 + 12 = 0
then simplify some more
9x + 21x = 30x
(-25) + (-35) + 21 + 12 = -13
30x - 13 = 0
now add 13 to both sides, 13 and -13 cancel each other out and it becomes
30x = 13
then you divide by 30 to get x by itself. 30 cancels itself out and you are left with 13/30 which doesn't simplify so that shod be your answer! I couldn't figure out 14 but I hope this helps!!!
Answer:
4 x
)
Step-by-step explanation:
(6 x
) / (1.5 x
)
= (
x
) / (
)
= (
x
) x (
)
=
x 
= 4 x 
This is an odd question because it's a little subjective, but, for me, I would choose x from the second equation because you could simply add 12y to both sides, then divide by 3. It has the added benefit of not having any decimals/fractions, or negative values, which would be nice for substitution.
Answer:
610 seeds
Step-by-step explanation:
b + 5b + 10 = x
- if b = 1 pack of sunflower seeds, then b = 100
- with this in mind, substitute 100 in for b
100 + 5(100) + 10 = x
600 + 10 = x
610 = x
I think it is 380 but I am not sure
