Answer: y - 0.18y
Step-by-step explanation:
From the question, Emerson practice a game that was on sale for 18% off the sales tax in his country.
Let y represent the original price of the game. The be used to determine the final cost of the game will be:
We have to subtract the 18% discount from the original price to get the final cost of the game. This will be:
= y - (18% of y)
= y - (18/100 × y)
= y - (0.18 × y)
= y - 0.18y
The final expression is y-0.18y
Answer:
$9.25
Step-by-step explanation:
let x = the cost of a child ticket
3(x)+2(x+3.50)=35.75
3x+2x+7=35.75
5x=28.75
x=5.75 cost of child ticket
5.75+3.50= 9.25
Answer:
Vertex : 5
Y - intercept : (0,-4)
Step-by-step explanation:
-4 is on the y-axis.
Vertex is the maximum or the minimum point of the parabola.
Answer:
The value of x is 21.
Step-by-step explanation:
Since this is a right angle triangle, you can apply Pythagoras theorem, side² + side² = hypo² :
(x + 3)² + 10² = (x + 5)²
x² + 6x + 9 + 100 = x² + 10x + 25
x² + 6x + 109 - x² - 10x - 25 = 0
-4x + 84 = 0
-4x = -84
4x = 84
x = 84 ÷ 4
x = 21 units
...it’s 0.21 because 21% is 21/100 which makes it 0.21
