Answer:
9 people
Step-by-step explanation:
Start by writing an equation.
The total bill is 134.03. The bill is totally paid by Marcus and the other guests. This will go on the other side of the equation.
Since we don't know how many guests there were, we can use variable x to represent the value that we're trying to find.
So here is our equation.
134.04 = 20.45 + 12.62x
Now, just solve for x, or isolate x.
Subtract 20.45 from both sides.
134.04 - 20.45 = 12.62x
Divide both sides by 12.62.
113.59/12.62 = x
Simplify.
x = 9
Since x is 9, we know that there were 9 other people at the dinner party.
The answer is A ratio table.
Answer:
a = 10
b = 6.633
Step-by-step explanation:
x²+ y²= 125.
In this equation, the value of x and y represent the coordinates of x and y respectively of point on which the circle passes.
<u>(a,5)</u>
x²+ y²= 125
a² + 5² = 125
a² + 25 = 125
a² = 125-25
a² = 100
a = √100 = 10
(9,b)
x²+ y²= 125
9² + b² = 125
b² 125 - 81
b² = 44
b = √44 = 6.633
