Answer:
<h2>(4x+z)=13000------1</h2><h2>(4x+z)13000=503000----2</h2>
Step-by-step explanation:
let x be the number of seats in A,
y be the number of seats in B, and
z be the number of lawn seats.
y=3x
the total number of seats is given by
(x+y+z)=13000
put y=3x
(x+3x+z)=13000
(4x+z)=13000------1
also
(4x+z)13000=503000----2
hence the systems of equation is
(4x+z)=13000------1
(4x+z)13000=503000----2
Answer:
x=2
Step-by-step explanation:
First multiply both sides by 2:
6x-10=4-x
Move the variable to the left-hand side and change its sign:
6x-10+x=4
Move the constant to the right-hand side and change its sign:
6x+x=4+10
Collect like terms:
7x=14
Divide both sides of the equation by 7:
x=2
Answer:
3x + y - 3
Step-by-step explanation:
<u>Like Terms</u>: In algebra, like terms are terms that have the same variables and powers.
To simplify this expression and get an expression that is eual to 5x + 3y - 2x - 2y - 3 I used <em>like terms</em> :
(5x - 2x) + (3y - 2y)
(5x - 2x = <em>3x</em>) + (3y - 2y = <em>1y or y</em>)
3x + y
Then we add the <em>- 3 </em>at the end giving us:
<u><em>3x + y - 3</em></u>
Answer:
y = 3x - 14
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 = 3x - 4 is in this form with slope m = 3
• Parallel lines have equal slopes, hence
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (4, - 2) into the partial equation
- 2 = 12 + c ⇒ c = - 2 - 12 = - 14
y = 3x - 14 ← equation of parallel line
-15 is already rational itself, but it as a fraction:
-15/1
