Numerical expressions contain numbers, while algebraic expressions contain variables and numbers.
<u>Numerical Expression</u>
"Difference" indicates that we'll be subtracting 13 from 48.
48 - 13 = 35
<u>Algebraic Expression</u>
Variables represent the unknown number, in this case the difference between 48 and 13. Let d represent the difference between the two.
48 - 13 = d
35 = d
16 x w x 8 = 1664
<span>w = 1664 / 16*8 = b) 13 cm</span>
1.
7x - y = 5
Isolate y
Add y
7x = y + 5
Subtract
y = 7x - 5 2.
5x - 3y = 0
Isolate y
Add y
5x = 3y
Divide
y = 1.66x 3. v=iwh
Isolate w
Divide h
v/h = iw
Divide I
v/hi = w
It’s $5,520
you would do 92,000 x 0.06 to find the answer
