Answer:
x= -15 or (7x+5)
Step-by-step explanation:
Simplifying
4x + 10 = 3x + -5
Reorder the terms:
10 + 4x = 3x + -5
Reorder the terms:
10 + 4x = -5 + 3x
Solving
10 + 4x = -5 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
10 + 4x + -3x = -5 + 3x + -3x
Combine like terms: 4x + -3x = 1x
10 + 1x = -5 + 3x + -3x
Combine like terms: 3x + -3x = 0
10 + 1x = -5 + 0
10 + 1x = -5
Add '-10' to each side of the equation.
10 + -10 + 1x = -5 + -10
Combine like terms: 10 + -10 = 0
0 + 1x = -5 + -10
1x = -5 + -10
Combine like terms: -5 + -10 = -15
1x = -15
Divide each side by '1'.
x = -15
Simplifying
x = -15
326/1000
AND
0.3260
IN THE FIRST ONE I HUST CONVERTED IT INTO A FRACTION AND IN HE SECOND ONE ,i' not sure if it's right. but I hope that the first one helps
Amount paid for the first book is $17.
Amount paid for the second book is 0.75 x 8 = $6
Total amount paid = $17 + $6 = $23
Total full cost of the two books = $17 + $8 = $25
Amount of discount = $25 - $23 = $2
% reduction =

Therefore, the <span>percent of the total cost of the two books reduced during the sale</span> is 8%
2x²-2x-12=0
simplify it into x²-x-6=0
factored form: (x-3)(x+2)=0
solutions: x-3=0 or x+2=0
x=3 or x=-2
Not sure how to explain "what the solutions mean for the equation". One thing you can say is that the solutions mean the equations have two roots/two zeros: 3 and -2, or the graph of 2x²-2x-12 intersects the x axis at (3,0) and (-2,0).
Seems like you could just find the speed of the plane with (720*2)km/10hr.
