Answer:
On #7.
Step-by-step explanation:
12(3+y)=5(2y+8)=
12y+36=10y+40=
12y-36=10y+40-36=
12y=10y+4=
12y-10y=4
2y=4
2y/2=4/2
y=2
20 hours because 1 mile is 1 hour so 4 miles is 4 hours so if you times the 5 days by the 4 miles/ hours you get 20 hours in 5 days.
ANSWER
I. The GCF of 6 and 16 is 3. FALSE
II. The LCM of 6 and 16 is 48. TRUE
III. 6 and 16 are both composite numbers. TRUE.
EXPLANATION
The GCF of 6 and 16 is not 3.
It is rather 2.
Factors of 6: {1,2,3,6}
Factors of 16:{1,2,4,8,16}
3 is not even a factor of 16.
The LCM of 6 and 16 is 48. This statement is true.
Composite numbers have more than 2 factors.
6 and 16 are both composite numbers.

Answer:
The answer is below
Step-by-step explanation:
Let x represent the amount of iron, y represent the amount of potassium and z represent the amount of mulch.
Since the supplement weighs 16 lb, hence:
x + y + z = 16 (1)
Also supplement contains thirteen times as much mulch as iron. Therefore:
x = 13z
x - 13z = 0 (2)
The supplement also has twice as much potassium as iron, hence:
x = 2y
x - 2y = 0 (3)
solving equations 1, 2 and 3 simultaneously gives:
x = 10.1 lb, y = 5.1 lb, z = 0.8 lb
This means that the soil supplement contains 0.8 lb of mulch
