Answer:
c. w = -1
Step-by-step explanation:
you have to add 2 with -3 and you get -1.
To answer this you will need to determine which area made with the 12 square tiles would give the shortest perimeter.
Think of all the combinations to get 12 square inches
1x12, 2x6, and 3x4. The perimeters of these are 26 in, 16 in, and 14 in.
You should arrange your tiles using the 3 x 4 option. You would need 14 stones.
the answer should be 49mm
28*7 / 4 = 49

Answer:
and
Step-by-step explanation:
Assume that Mike bought only cookies and hot dogs.
The total can be represented as:
--- (1)
And the amount spent can be represented as:
--- (2)
Required
Determine the system of equation
Let c represents the number of cookies and h, number of hot dogs.
implies
And
Cost of cookies = 0.75 * c
Cost of hot dogs = 1.10 * h
So, we have:
Hence, the equations are:
and
Solving for c and h
Make c the subject in
Substitute 5 - h for c in
Collect Like Terms
Solve for h
-- approximated
Recall that:
