Answer:
x = 83
Step-by-step explanation:
The sum of the angles of a quadrilateral is 360
75+x+97+105 = 360
Combine like terms
x+277=360
Subtract 277 from each side
x+277-277=360-277
x = 83
Hi there!
We know that the formula for the area of a rectangle is height * width. Thus, we can multiply these two expressions together:
Now, we know through the distributive property that we can distribute the 
to everything in the parenthesis. Once this is done, we get:
Now, we know through the power rule that when two exponents are multiplied together with the same base, the exponent can be added together 
. This then would make our equation:
Giving us for our final answer:
Hope this helps!

Answer:
Part A
x = liters (the milk and water)
0.2 x + 1 = x
Part B
0.2 x + 1 = x
0.8 x = 1
x = 1 : 0.8 = 1.25 liters
Milk
1.25 x 0.2 = 0.25
