I believe the answer is A because a reflection over the y-axis and one over the x-axis is the same as a reflection over the origin<span />
X/5 - 3 < 5....add 3 to both sides
x/5 < 5 + 3
x/5 < 8....multiply both sides by 5, eliminating the 5 on the left side
x < 8 * 5
x < 40 ...... ur solution
* and just so u know, x/5 is the same as (1/5)x....in case u wanted to solve it a little different........1/5x < 8...u would divide both sides by 1/5.....x < 8 / (1/5).....x < 8 * 5/1......x < 40....u will still get the same answer
The length of the unknown leg of the triangle is 15 m.
<u>Step-by-step explanation:</u>
Length of one leg = 20 m
Length of the hypotenuse= 25m
As it is a right angled triangle we can use pythogoras theorem.
Let the unknown length be y
(20) (20) + y(y) = (25) (25)
400 + y(y) = 625
y(y) = 225
y = √225
y = 15
The length of the unknown leg is 15 m.
Answer : D
Cross multiply:
9n + 63 = 8n + 40
Subtract 63 from both sides:
9n + 63-63= 8n + 40-63
Simplify:
9n=8n-23
Subtract 8n from both sides:
9n-8n= 8n-23-8n
Simplify:
n=-23
