Answer:
450-3x
Step-by-step explanation:
He starts with a container filled with 450 grams. Each day, he removes 3 grams to make a cup of tea. In other words, every day, he subtracts 3 grams from the total 450 grams.
450-3x
This would be our expression. He starts with 450, and every day, x, removes 3 grams.
Just substitute their values into the expression:
= -8 + 9 + 5z + 7x
= -8 + 9 + 5(3) + 7(5)
= 1 + 15 + 35
= 51
In short, Your Answer would be 51
Hope this helps!
Answer: look up alaskan pipeline
Step-by-step explanation:
Though we cannot exactly find PT, we can find it in terms of TQ.
Multiply the second equation by 7/6 to get 7TQ/6=7x-7/3. Subtracting 65/3 from both sides, we get 7TQ/6-65/3=7x-24. Since the right side is equal to PT, PT=7TQ/6-65/3.
Let x units be the length of the shortest side of the triangle.
Perimeter of triangle = 2(x + 1) +x = 3x + 2
Perimeter of square = 4(x - 2) = 4x - 8
Equating the two expressions for perimeters, we get:
3x + 2 = 4x - 8
The solution is: x = 10
The answer is 10 units.
