X of 20% = y
x - y = 75
x = total amount
y = discounted amount
x * 20/100 = y
x * 0.2 = y
replace y with 0.2x in other equation
x - y = 75
1x - 0.2x = 75
0.80x = 75
x = 75/.8
x = 93.75
Check:
93.75 * 20/100 = 18.75
93.75 - 18.75 = 75
x = 93.75
y = 18.75
Answer: Total amount without discount is $93.75
//BTW not sure about this, but kind of make sense
Answer:
54
Step-by-step explanation:
To solve this, you have to find the area of the square then the area of the triangle, and add them together.
To find the are of a square you multiply the base by the height.
Example: 6 × 6 = 36
To find the area of a triangle you multiply the base by the height and divide it by 2.
Example: 6 × 6 = 36
36 ÷ 2 = 18
Now we add both areas together.
Example: 36 + 18 = 54
Answer:
x=2
Step-by-step explanation:
divide -5 to both sides to isolate the x. two negatives make a positive therefore x=2.
i hope this helps :)
