Y<1-6x
Insert the values of
x
=
x
=
and
y
=
y
=
into the equation to find if the ordered pair is a solution.

Divide each term by

OK so each block is 3cm tall and 3.5cm wide (because 2 are 7cm wide)
so to measure the perimeter count all the side values for example:
the 5 squares at the bottom which measure 3.5cm each adds up to a total of 17.5cm then if you add the top 2 flat sides that's another 2, 3.5cm which adds up to 7cm. 17.5cm + 7cm = 24.5cm then their are 3 walls on each side measuring 3cm each so 3cm * 6 = 18
24.5cm + 18cm = 42.5cm (I think this is correct)
Answer:
-7x+11 is simplified version of -3x-4x+11
Answer: 6.4 degrees
Step-by-step explanation:
a= 5 degrees temperature difference to the north gives the opposite of the triangle,
b = 4 degrees temperature difference to the west gives the adjacent,
c = temperature difference of 1 mile to the south east gives the hypotenuse.
Therefore,
Using Pythagoras equation,
c² = b² + a²
c = sqrt( 5² + 4²)
c = sqrt(41) = 6.4 degrees
Therefore, there will be 6.4 degrees temperature difference 1 mile to the south east
