Answer:
Assuming they bought the same shoes, $82.5
Step-by-step explanation:
80% of Original Shoe price = $82
Divide by 0.8 to find the original price.
82 / 0.8 = 102.5
102.5-20=82.5
Answer:
Step-by-step explanation:
9 + 4x = 52
4x = 43
x = 10.75
4(10.75) = 43
Hey there, Byanatwin2!
To solve this inequality, we need to isolate x, like any other equation or inequality.
So, to isolate x we need to divide both sides by
NOTE: We are dividing by a number less than 0, or a negative number so
the sign > will change to <
Now, to divide a fraction, we need to do the reciprocal and then multiply. The reciprocal of
is
Then, we multiply 8 times
and we get a total of -12
So the answer should be x < -12

Answer:
$212.5
Step-by-step explanation:
x= 100*170/80
x= 17000/80
x= 212.5
Answer:
A rational number can expressed as a whole number, integer, square root, fraction, and more as long as it's not imaginary. However, the number has to be clean like 1/2=0.5, 1/3=0.333, -1, 200. If it is a number that goes on forever and is not repeated like 1.22222, then it's an irrational number like pie-3.14159..., 5/0, 2.201845. If you have an imaginary number- 6i, then this would be considered as non real numbers like x+2, red, wind, and y/7.
