Answer:
<u>denominators</u>
Step-by-step explanation:
This is vocabulary term definition (for "least common denominator"). This missing word is "denominators."
You collect the “like terms” and simplify which would bring you down to 1789b which is equivalent to 1345b. Then you move the “variable” to the “left-hand” side and change its sign which would give you 1789b-1345b=0. Then again collect the “like terms” which would bring you 444b=0. Then you divide the both sides of the equation by 444 and it would mean b=0. So your answer is b=0
Complete question :
A restaurant customer left $0.90 as a tip. The tax was 8% and the tip was 10% of the after tax cost. Which information is not needed to compute the bill after tax and tip? What was the total bill?
Answer:
The tax percentage
9.9
Step-by-step explanation:
Guven that :
Amount of tip left = 0.90
Tip left = 10% of after tax cost
Tax % = 8%
If tip left = 10% of after tax cost; then ;
If after tax cost = x
10% of x = 0.90
0.1x = 0.9
Hence the percentage tax isn't needed :
To obtain the total bill:
Let total bill = y
y = after tax cost and tip
Hence,
y = x + tip
y = x + 0.9
From : 0.1x = 0.9 ; x = 0.9/0.1 = 9
Hence,
Total bill:
y = 9 + 0.9
y = 9.9
Your answer will be y=-3x+2
