Justin is taking a taxi cab to pick up his car from the auto shop. The taxi charges an initial fee of $5.00 and additional $2.50 for each mile the taxi drives. Write an equation using x as the number of miles, to determine how many miles the taxi drove if Justin spent $25.00. Use your equation for the number of miles. (Define the variable please, write an equation, and solve & label:))
Answer:
x = 8
Step-by-step explanation:
Given the initial fee of $5.00, and the additional cost of $2.50 for every mile the taxi drives:
We can establish the following cost function:
C(x) = 2.50x + 5.00
Where:
C(x) = total cost of taxi fare (same as the variable, "y" in linear equation)
x = number of miles driven
$5.00 = initial or flat fee (same as the y-intercept, "b," in linear equation).
We can find out the number of x miles the taxi drove for the $25.00 total cost that Justin paid for the fare:
C(x) = 2.50x + 5.00
$25 = 2.50x + 5.00
Subtract 5.00 from both sides of the equation:
$25 - 5.00 = 2.50x + 5.00 - 5.00
$20 = 2.50x
Divide both sides by 2.50 to solve for x:
[tex]\frac{20}{2.50} = \frac{2.50x}{2.50}[/tex]
8 = x
Justin spent $25 for a taxi ride that travelled for 8 miles.

Find the graphed solution to the inequality. 3(x-9) < -18
Answer:
[tex]x<3[/tex]
Step-by-step explanation:
[tex]3\left(x-9\right)<-18[/tex]
Divide both sides by 3
[tex]\frac{3\left(x-9\right)}{3}<\frac{-18}{3}[/tex]
[tex]x-9<-6[/tex]
Add -9 to both sides:

“To find 623, I can just take the value of 613 then either multiply it by 12 or divide it by 2.” Do you agree with her? Explain why or why not.
Step-by-step explanation:
613 and 623 are very close values.
multiplying by 12 or a division by 2 changes the starting value drastically.
so, this cannot be right.
and dividing 613 by 2 also makes it even smaller. but to get 623 we need to make it bigger.
so, therefore, even without actually calculating the numbers, the statement is proven false.
. Imagine you are a restaurant owner. You are trying to set the menu price for the seared scallops with rice and mango salsa. Your item food cost is $6.78 and you set your food cost percentage to 33%. What would you set the price to be on the menu? *
1 point
$16
$18
$20
$21
The price of the food on the menu will be set at $21.
Cost of food item = $6.78
Food cost percentage = 33%
Let the price on the menu be represented by x.
Therefore, based on the information given, the equation to solve the question will be:
= 33% × x = $6.78
33/100 × x = $6.78
0.33 × x = $6.78
0.33x = $6.78
x = $6.78/0.33
x = $20.54
x = $21 approximately
Therefore, the price of the food on the menu will be set at $21.

The waves will cover a circular area of 7542.96 miles.
What is the area of the circle?The circle is defined as the locus of the point traces around a fixed point called the center and is equidistant from the outer trace. The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
Given that a radio station sends out radio waves in all directions from a tower at the center of the circle of broadcast range. The circle has a diameter of 98 miles.
The area of a circle is calculated by the formula below:-
Area = ( π / 4 ) d²
Area = ( π / 4 ) ( 98 )²
Area = 7542.96 square miles
Therefore, the waves will cover a circular area of 7542.96 miles.

A triangle has sides with lengths of 17 inches, 20 inches, and 28 inches. Is it a right triangle?
Answer:
no
Step-by-step explanation:

the hypotenuse side is always the longest so its 28
:
