Solve for x.
- 1 /2 (x + 5) = -10

Answers

Answer 1

Answer: -1/2(x+5=-10
multipl yboth sides by -1 since I don't like negatives
1/2(x+5)=10
multiply both sides by 2/1 to clear fraction
x+5=20
subtract 5
x=15

Answer 2

Answer: ANSWER: x=15

ORIGINAL EQUATION:
-1/2(x+5)= -10

Simplify by multiplying (x+5) by (-1/2)
-0.5x+(-2.5)= -10

Add 2.5 on both sides
-0.5x= -7.5

Divide by -0.5 on both sides
x=15

Tania is going to make soup. She combines 225 grams of water with 300 grams of condensed soup. Tania then adds 50 grams of celery and 10 grams of carrots. How much soup does Tania have before she warms it on the stove?

Answers

Answer:

375 grams of soup sir I hope this helps

Final answer:

Tania has a total of 585 grams of soup before she warms it on the stove. This is found by adding the weight of all the ingredients she used: water (225g), condensed soup (300g), celery(50g), and carrots(10g).

Explanation:

The subject of this question is about adding quantities, which falls under Mathematics. Tania combines multiple ingredients to make soup. She uses 225 grams of water, 300 grams of condensed soup, 50 grams of celery and 10 grams of carrots. To find out the total amount of soup she has before warming it up, you simply need to add up all these amounts. So, 225g (water) + 300g (condensed soup) + 50g (celery) + 10g (carrots) = 585 grams. Therefore, Tania has 585 grams of soup before she warms it up on the stove.

(25 points)Which statement best describes the graph of x^3 - 3x^2 - 4x + 12?

It starts down on the left and goes up on the right and intersects the x-axis at x = -2, 2, and 3.
It starts down on the left and goes up on the right and intersects the axis at x = -2, 4, and 3.
It starts up on the left and goes down on the right and intersects the axis at x = -2, 2, and 3.
It starts up on the left and goes down on the right and intersects the axis at x = -2, 4, and 3.

Answers

The answer is A.

The 0's of the function are -2, 2, and 3.

The graph starts from the bottom left and it keeps going to the top right.

x³ - 3x² - 4x + 12=(x³ - 3x²) - (4x - 12)=x²(x-3)-4(x-3)= (x-3)(x²-4)=(x-3)(x-2)(x+2)
equation cross x-axis in point x=-2, x=2, x=3

On a vacation to Puerto Rico Rose jumped off a cliff into a river in Elion forest preserve her height as a function of time to be modeled by the function HFT equal 16 T squared +16 T +480 where T is the time after jumping in seconds and H is the height in feet how many seconds it take Rose to hit the water round your answer to the nearest hundredth

Answers

To solve for t, you will use the equation given: -16t^2 + 16t + 480 = 0. First, simplify the equation by dividing everything by 16: -t^2 + t + 30 = 0. Then complete reverse FOIL: (-t + 6)(t + 5) = 0. Next, set each of these equations to 0 separately, and solve for t. You will get t = 6, and t = -5. Since time can't be negative (Rose can't have hit the water after a negative number of seconds), the answer is 6.

Explain why you cannot use mass or volume alone to identify substances.

Answers

That is because mass and volume depend on the size of the sample. The same substance can come in different sizes in which its mass and volume would be different.
