Answer:
ummmm what did he sayyyyyyyyy
Step-by-step explanation:
In order to find the original price, we need to divide by 4. This is because the price was reduced by 20%, it is 4/5 of the original price.
By dividing by 4, we can see that 90.40 is 22.60.
To find the original price, we add 22.60 (1/5 of the original price), to 90.40 (4/5 the original price) to find that $113 is the original price.
Answer:
(3, 1)
Step-by-step explanation:
(a) Algebraic solution
(1) y = -⅔x + 3
(2) y = 2x - 5
Set Equation (1) equal to Equation (2)
-⅔x + 3 = 2x - 5
Multiply each side by 3
-2x + 9 = 6x - 15
Add 15 to each side
-2x + 24 = 6x
Add 2x to each side
24 = 8x
Divide each side by 3
(3) x = 3
Substitute (3) into (2)
y = 2×3 - 5 = 6 - 5 = 1
The ordered pair that makes both equations true is (3, 1).
(b) Graphical solution
In the diagram below, the red line is the graph of Equation (1). The blue line is the graph of Equation (2). The point of intersection is at (3, 1).
(z+1.2)/5=3.6
quotient: division
The Pythagorean theorem formula for a triangle is A^2 + B^2 = C^2 where A and B are the sides and C is the hypotenuse.
The sides of the triangle shown are AB and BC and the hypotenuse is AC,
so the correct answer would be:
(AB)2 + (BC)2 = (AC)2, because 25 + 144 = 169
