A. f(x) = 0.75xb. g(x) = x - 5c. $88.75d. Yes, if you do f(x) before g(x) or g(x) before f(x), you get different final prices.
Answer:
n = 20
Step-by-step explanation:
The problem says that there is a number (n) that is added to 1/5 of itself ((1/5)*n), and that sums is equal to 24, so the equation that models the problem is:
n + (1/5)*n = 24
Taking the least common multiple in the left side, which is 5:
(5n + n)/5 = 24
6n = 120
n = 120/6
n = 20
Pls. see attachment. I created that table for easy monitoring and understanding.
Yellow cells are sums that are even.
Orange cell are sums that are multiples of 3.
Yellow cells w/ orange texts are sums that are both even and multiples of 3.
By looking at the units they use in the situation like if it ha m, k, mph
Answer:
∠AEX = 70°
Step-by-step explanation:
From the diagram
AX ≅ BX
BY ≅ CY
AZ ≅ CZ
∠XAE = 20°
A circumcenter has equal distant from vertices of the triangle since radii of circles are congruent.
For the given figure, the midpoints is at Z, X, Y
And the perpendiculars also occur at Z, X, Y
∠Z = 90°
∠X = 90°
∠Y = 90°
∠XAE ∠AXE +∠AEX= 180° (sum of angles in a triangle)
∠AXE = ∠X = 90°
20° + 90° +∠AEX= 180°
110° +∠AEX= 180°
∠AEX = 180°-110°
∠AEX = 70°
