Answer:
w = - 
Step-by-step explanation:
3 1/4 = 1/2 + w
Cross Multiply
31(2 + w) = 4
Divide both sides by 31
= 
(simplify) -> 2 + w =
Subtract 2 from both sides
2 + w - 2 + - 2 (simplify) -> -
w = -
Answer:
The other length is 9cm
Step-by-step explanation:
Area of rhombus is Base x height
Base is one length
Height is another
A = bh
144 = 16h
h = 144/16 = 9cm
remember, you can do anything to an equation as long as you do it to both sides
we can do a subsitution
y=x+6
y=-7x-10
since y=x+6, we can subsitute x+6 for y in the other equation
y=-7x-10
x+6=-7x-10
add 7x to both sides
8x+6=-10
minus 6 from both sides
8x=-16
divide both sides by 8
x=-16/8=-2
the valu eof x that satisfies both equations is x=-2
Answer:
$219.98
Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:
Height of the Willis Tower in Chicago = 1,454 feet
Scale of the model = 2 inches : 45 feet height
2. How tall is the height?
For answering that question, we will use the following expression:
Height of the model = Height of the Willis Tower in Chicago/Scale in feet * Scale in inches
Replacing with the real values, we have:
Height of the model = 1,454/45 *2
Height of the model = 32.31 * 2 = 64.62 inches
64.62 inches/12 = 5.39 feet
The model is 64.62 inches of height or 5.39 feet
