Answer:
Issac's dog weighs 19 pounds
Step-by-step explanation:
Let x be Issac's dog's weight
- Translate the problem into an algebraic expression: x + (x + 12) = 50
- Simplify: 2x + 12 = 50
- Subtract 12 from each side, so it now looks like this: 2x = 38
- Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 19
I hope this helps!
Answer:
c) Length = 12, width = 8 and height = 23.
Step-by-step explanation:
Let the length be x, then the width = x - 4 and the height = 2x - 1.
a) The polynomial is x(x - 4)(2x - 1)
b) x(x - 4)(2x - 1) = 2208
c) x(x - 4)(2x - 1) - 2280 = 0
2x^3 - 9x^2 + 4x - 2280 = 0
I'll use graphical software to find a solution for this. Its easily obtained online.
There is one real root and its x = 12.
So the dimensions of the box are L = 12, W = 8 and H = 23 inches.
Answer:
<h2>x < - 3</h2>
Step-by-step explanation:
Move 7 to the other side of the inequality
Divide both sides by - 5
Reverse the sign
We have the final answer as
<h3>x < - 3</h3>
Hope this helps you
