$7x-6>-19$

Step-by-step explanation:

We have to translate the given situation into mathematical form

Let x be the number then

"the product of 7 and a number"

$7x$

"Six subtracted from the product of 7 and a number"

$7x-6$

"is greater than -19"

$7x-6>-19$

Hence, the given scenario in mathematical form is:

$7x-6>-19$

Jamie is x years old. His friend Ana is the same age.

SSSSS [86.1K]

<h3>Answer: 2x</h3>

Explanation:

Each person is x years old. Adding those unknown ages gets us x+x = 2x

We can think of it like x being one box, so x+x represents having two boxes which shortens to 2x.

Need the answer to this

Olegator [25]

Answer:

4.5 per package

Step-by-step explanation:

Though they give us 4 different pairs of values on the table, we only need 1 pair to solve this question. For simplicity, lets chose the pair of whole numbers:

54 : 12

This is the ration of servings to packages, or the servings per package.

To get our answer, we must find how many servings per 1 package, so we need to divide by 12:

$\frac{54}{12} : \frac{12}{12}$

4.5 : 1

This means that there are 4.5 servings per 1 package!

Hope this helps!

Find a vector that is parallel to -9x+2y = 10. Please explain step by step

coldgirl [10]

Answer:

Step-by-step explanation:

Step One: Find the slope of the given Line

2y - 9x = 10 Add 9x to both sides

2y - 9x + 9x = 9x + 10 Combine

2y = 9x + 10

y = 9/2 x + 5

The parallel line has a slope of 9/2

Step Two: Find the magnitude

sqrt(x^2 + y^2) = r You don't have a magnitude. Invent one, r

x^2 + y^2 = r^2 Both sides have been squared

Step Three: Find the change in y / x

y / x = 9/2

Step Four: Find the value of y

y/x = 9/2 Multiply both sides by x

y = 9/2 * x

Step Five: Solve for x

x^2 + y^2 = r^2

x^2 +(9/2x)^2 = r^2

x^2 + 81x^2 / 4 = r^2 Change the 1 to common denominator 1 = 4/4

4/4 x^2 + 81x^2/ 4 = r^2

85 x^2/ 4 = r^2 Multiply both sides by 4/85

4/85 * (85 / 4) x^2 = 4/85 r^2

x^2 = 4/85 r^2 Take the square root of both sides

x = +/- 2/sqrt(85) r Rationalize the denominator

x = (+/- 2 sqrt(85) ) / 85 *

Step Six: Solve for y

y = 9/2 x

y = 9/2 * 2 sqrt(85) / 85 Cancel the 2s

y = +/- 9* sqrt(85)/85

Answer

<2*sqrt(85)/85 , 9 sqrt(85)/85>

You can write the minus answer if you need it. I kind of suspect you won't.
