Y varies inversely with x, if y = -12 when x = 8 what is x when y = -9

Answers

Answer 1

Answer:

either 5 or 11

Step-by-step explanation:

(8, -12)

(5, -9) or (11, -9)

If y varies consistently with x then it would copy what happens, in a manner of speaking.

In this case, y increases by three, x would either add 3 or subtract 3

I am not completely sure on this.

Do these ratios form a proportion 12/16 and 15/20

Answers

Answer:

This is a proportion

Step-by-step explanation:

Cross multiply:

12 * 20 = 16 * 15

Simplifying:

12 * 20 = 16 * 15

Multiply 12 * 20

240 = 16 * 15

Multiply 16 * 15

240 = 240

Add '-240' to each side of the equation.

240 + -240 = 240 + -240

Combine like terms: 240 + -240 = 0

0 = 240 + -240

Combine like terms: 240 + -240 = 0

0 = 0

Solving

0 = 0

Jim is making salsa. His recipe calls for 3 1 3 cups of tomato sauce for every 1 6 cups of cilantro. If Jim has 1 cup of cilantro, how many cups of tomato sauce will he need?

Answers

Answer: 20 cups of tomato

Step-by-step explanation:

From the question, we are informed that Jim is making salsa and that his recipe calls for 3 1/3 cups of tomato sauce for every 1/6 cups of cilantro.

If Jim has 1 cup of cilantro, thus simply means that he has multiplied the previous cup of cilantro by:

= 1 ÷ 1/6

= 1 × 6/1

= 6

Therefore, we would also multiply the cups of tomato by 6. This will be:

= 3 1/3 × 6

= 10/3 × 6

= 20 cups of tomato

the sum of two and a number is less than five

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the English statement

''The sum of two and number is less than five''.

Let us breakdown the statement.

Let 'n' be the number. The sum of two and number = 2 + n

We know that the less than symbol is denoted by '<' which is used for comparison.

Thus, the statement 'The sum of two and a number is less than five' is algebraically represented as:

2 + n < 5

Let us solve the algebraic expression.

[tex]2+n<5[/tex]

Subtract 2 from both sides

[tex]2+n-2<5-2[/tex]

Simplify

[tex]n<3[/tex]

Thus, the solution is:

[tex]2+n<5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:n<3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:3\right)\end{bmatrix}[/tex]

Answers

Answer:

16 1/2 gallons of water.

Step-by-step explanation:

Since 4 bottles can hold 8 gallons, and you need to know how much 10 can hold, you can multiply 4 and 8 times 2 so you get 8 and 16, and then if you choose 10 instead of 8 instead you would get the result of 10 bottles being able to hold 16 1/2 gallons of water.

The park covers over one million acres. The park is open year-round and more than two million people visit each year. The terrain in the park varies from tall mountains to flat prairies. The mountains in Glacier National Park are part of the Rocky Mountain range. They were formed long ago when tectonic plates below the earth's surface collided and caused the land to rise. These mountains are now home to animals such as bighorn sheep, marmots, and mountain goats. There are numerous types of trees near the base of most of the mountains, but the numbers and types of trees decrease as the elevation of the mountains increases. Visitors to the mountains can hike on the trails in the summertime and cross-country ski on the slopes in the wintertime. In contrast to the high mountaintops, the prairies in Glacier National Park are found in low to mid-elevation areas. These wide, open spaces contain a variety of plants and animals. Wildflowers dot the landscape. Elk and prairie dogs roam the land. Visitors can go on a horseback ride or stay overnight at a campground. A photovoltaic cell produces electricity when the sun shines.
