Answer:
7 1/8 or 7.125
Step-by-step explanation:
first subsitute z for 4
28/4 - 4/4 + 1 1/8
then do 28/4 - 4/4 which is 6,
add that to 1 1/8
and get 7 1/8
Answer:
3/8 = 9/24
1/3 = 8/24
3/8 > 1/3
Step-by-step explanation:
3/8 = 9/24 (multiply both numerator and denominator by 3)
1/3 = 8/24 (multiply both numerator and denominator by 8)
9/24 > 8/24
The x^2 over the x is like subtracting x from x^2, so the new equation would be 9-x/-3. You divide 9 by -3 to get the final answer of -3-x, or -x-3, which is E.
