Do a proportion
60/100= x/54
Cross multiply and divide
54 x 60= 3,240
3,240 divided by 100 is 32.4
Now subtract
54- 32.4= 21.6
Answer is $21.6
Answer:
aquí está
Step-by-step explanation:
- 7x+3-6x=6x-3-6x
- x+3=-3
- x+3-3=-3-3
- x=-6
The answer would be 3x+3 equals 6x << answer :)

Answer:
<h2>
b) y = -3x - 7</h2>
Step-by-step explanation:
3x + y = 5 {subtract 3x from both sides}
y = -3x + 5 ← slope-intercept form
y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂
{Two lines are parallel if their slopes are equal}
y = -3x + 5 ⇒ m₁ = -3 ⇒ m₂ = -3
(-1, -4) ⇒ x₁ = -1, y₁ = -4
The point-slope form:
y - (-4) = -3(x - (-1))
y + 4 = -3(x + 1)
y + 4 = -3x - 3 {subtact 4 from both sides}

Answer:
(5/6, 8/5)
Step-by-step explanation:
We multiply the second equation by 2, and then add the equations together.
12x+15y=34
-12x+10y=6
------------------
25y=40
We divide by 25 on both sides, and get that y = 8/5. We substitute y into either of the equations.
-6x +5(8/5)=3
Do the multiplication.
-6x+8=3
Subtract 8 from both sides.
-6x=-5
Divide by -6 on both sides.
x=5/6.
