Multiplication is when you times two different numbers together where its negative or postive(you can multiple pretty much anything together)but combining like terms are number or letters thats the same. For instance, say if i have 4x+7-2x+3, i would combine each term that has something in common with it,like, 4x and 2x because both has X and i will combine 7 and 3 because those two are regular numbers and does not have an X like the others. I Hope That helps!

Answer:
Venus fly trap = 12
Bonsai tree = 17
Step-by-step explanation:
Given that :
Venus fly trap = $3per plant
Bonsai tree = $5 per plant
Number of plants sold = 29
Total cost of plant sold = $121
Let venus fly trap = x ; bonsai tree =y
x + y = 29 ___ (1)
3x + 5y = 121 ____(2)
From (1) :
x = 29 - y
In (2):
3(29 - y) + 5y = 121
87 - 3y + 5y = 121
87 + 2y = 121
2y = 121 - 87
2y = 34
y = 34/2
y = 17
x = 29 - 17
x = 12
Hence,
Venus fly trap = 12
Bonsai tree = 17
Answer:
59/ 60
Step-by-step explanation:
1.9 can be expressed as 19/10
Thus, our equation becomes
19/10 -11/12.
This becomes (228 -110) / 120
= 118 / 120
Simplify by 2 to get
59/60
