No it's a lot easier to use percent equation because it's easier to correct if wrong and you can get a better understanding of percent equation.
< = less than
> = greater than
57 is less than(<) x minus(-) 19
57 < x - 19
Your answer is the 4th option because:
The 1st option is not the answer because 19 is subtracted by x when it should be x minus 19, and the sign is > when it should be <
The 2nd option is not the answer because it should be x minus 19
The 3rd option is not the answer because the sign is > when it should be <
Answer is
<span>d. Step 3: He should have divided both sides by −5.</span>
3/12 or 1/4 is left of the bread
2*4
-----= 8/12 - i did this for a common denominator
3*4
8 1 9
--- + --- = --- i did this to find the total eaten
12 12 12
12 9 3 1
--- _ --- = --- or simplified as ----
12 12 12 4
the total amount of bread left is 3/12 or 1/4 (simplified)
Answer:
The expression for the given discount on item is 74 - [0.4 × 74 + 1.07 × 74]
Step-by-step explanation:
Given as :
The market price of item = m.p = $74
The discount percentage on item = 40%
The sale tax added = 7%
The selling price = s.p = $74 + 7% of $74
I.e s.p = 1.07 × 74
<u>Now, from discount </u>
d % = 
Or, 40% =
Or, 0.4 = 1 - 
Or, 0.4 × 74 = ( 74 ) - (1.07 × 74)
Or, 74 - (1.07 × 74) - 0.4 × 74 = 0
Or, 74 - 74 (1.07 + 0.4) = 0
Or, 74 - [0.4 × 74 + 1.07 × 74] = 0
Hence, The expression for the given discount on item is 74 - [0.4 × 74 + 1.07 × 74] . Answer
