Answer:

This is proved with two property of equality subtraction and multipication property.

Step-by-step explanation:

Given $\frac{x}{6} + 2 = 15$

By subtraction property of equality

$\frac{x}{6} +2 - 2 = 15 - 2$

⇒ $\frac{x}{6} = 13$

Now by multiplication property

x = 13(6) = 78

Hence the result.

$\frac{x}{6} + 2 = 15$ ⇒ Start with equality property

$\frac{x}{6}=13$ ⇒ Using the subtraction/addition property to subtract 2 from both sides

$x = 78$ ⇒ Using the multiplication property (multiply both sides by 6)

x = 78

The number of books borrowed from a library each week follows a normal distribution. When a sample is taken for several weeks, t

Marat540 [252]

$\mathbb P(X>250)=\mathbb P\left(\dfrac{X-190}{30}>\dfrac{250-190}{30}\right)=\mathbb P(Z>2)\approx0.0228$

Or, if you're familiar with the empirical rule and the basic properties of the normal distribution, you can use the fact that approximately $95/%$ of the distribution lies within two standard deviations of the mean, or

$\mathbb P(|Z|$

which means about $5\%$ of the distribution lies outside this interval, or

$\mathbb P((-22))\approx0.05$

Because the distribution is symmetric, you have

$\mathbb P(-22)$
$\implies \mathbb P((-22))=\mathbb P(-22)=2\mathbb P(Z>2)\approx0.05$
$\implies \mathbb P(Z>2)\approx 0.025$

What are the end points of the triangle called? How are they labeled?

horrorfan [7]

For this case we have that by definition:

A triangle is defined by three lines that are called sides, or by three points called vertices.

We know that:

The vertices of a triangle are labeled with capital letters.
The sides of a triangle are written with lowercase letters.
The angles of a triangle are written similarly to the vertices.

Answer:

The end points of the triangle are called vertices.

They are labeled in capital letters.

Solve for x and simplify answer as much as possible

pantera1 [17]

Answer:

$x=-1$

Step-by-step explanation:

$4=6+2x$

Flip the equation:

$2x+6=4$

Subtract 6 from both sides:

$3x+6-6=4-6$

$2x=-2$

Divide both sides by 2:

$2x/2=-2/2$

$x=-1$

frez [133]

Answer:Roast beef- 32 turkey-80 Vegetarian-48

Step-by-step explanation:

This is the answer because if you divide 160 divide by 5 that gives you 32 for the roast beef. For the turkey you divide 160 and 3 that gives you 80. For the vegetarian you have to add 32 and 80 that gives you 112. Then, you subtract 160 and 112 that gives you 48. To check your answer you add 32, 80, and 48 that gives you 160.
