1) Option C is correct

2) Option B is correct

Step-by-step explanation:

Question no 1:

We need to find the constant of proportionality

The constant of proportionality can be found by using the formula y/x = k, where k is the constant of proportionality.

Finding k:

x = Hot pepper corn

y = chedder corn

So, y/x = 10/4 = 2.5

y/x = 20/8 = 2.5

y/x= 30/12= 2.5

So, Constant of proportionality is k = 2.5

Hence Option C is correct.

Question No 2

Every female rabbit has 5 baby rabbits. We need to find ratio of baby rabbits to female rabbits.

Baby rabbits = 5

female rabbits = 1

Ratio of baby rabbits to female rabbits: 5: 1 or 5/1 = 5

So, ratio of baby rabbits to female rabbits is 5

Option B is correct.

4-[6(3x+2)-x]+4 order of operations
weqwewe [10]

Answer:

-4 - 17x

Step-by-step explanation:

Anything enclosed in parentheses must be done first if possible.  (3x + 2) is inside two sets of parentheses, but nothing can be done with 3x + 2.  

Multiplication must be done next.  [6(3x+2)-x] becomes 18x + 12 - x, or

17x + 12.

Now we have 4 - 17x - 12 + 4.  Combining like terms through addition and subtraction, we get 4 - 12 + 4 - 17x, or -4 - 17x.
