let's say the bill without the tip is "x" amount, so that'd be the 100% of the bill, but we also know that 4.50 is the 18% of "x".
so if 4.50 is the 18% of "x", how much is "x"?
Answer:
20 centimeters
Step-by-step explanation:
27 / x = 12
x = 2.25 times
width would be 45 / 2.25 = 20 centimeters
Answer:
=7
Step-by-step explanation:
−7+11−(−3)
=4−(−3)
=7
From the expression 5x^23, we identify the terms as follows:
5 = <span>coefficient
</span>x = <span>variable
</span>23 = exponent
x = base
The coefficient is the constant in the term, the variable is any letter in a term, the exponent is the the number of times a number is being multiplied by itself in a power and the base is <span>the number being multiplied in a power.</span>
