The length is 15 feet.
Write them both as ratios!
6/10=9/x
6x=90
x=15
Answer:
measure of each angle of a regular octagon=360/8=45°
at the point, 60°+x+45=360°
x=255°
Answer:
I have to pay 20% of the regular price.
Step-by-step explanation:
Let the regular price of the item is $x.
Now, I have to pay 25%, if the regular price of the item was 20% taken off the regular price.
So, the price of the item after the 20% price is taken off the regular price is .
So, I have to pay 25% of that price, i.e.
Now, if I have to pay y% of the regular price, then
(Given)
⇒ y = 20%
Therefore, I have to pay 20% of the regular price. (Answer)
Answer:
5x - y = - 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 5x - 12 ← is in slope- intercept form
with slope m = 5
• Parallel lines have equal slopes , then
y = 5x + c ← is the partial equation
to find c substitute (- 2, - 6 ) into the partial equation
- 6 = - 10 + c ⇒ c = - 6 + 10 = 4
y = 5x + 4 ← in slope- intercept form ( subtract 5x from both sides )
- 5x + y = 4 ( multiply through by - 1 )
5x - y = - 4 ← in standard form
