Answer:

x < -3/2 OR x > 9  3/5

Step-by-step explanation:

12x+7<−11 OR 5x−8>40

Solve the inequalities separately

12x+7<−11

Subtract 7 from each side

12x+7-7<−11 -7

12x < -18

Divide each side by 12

12x/12 < -18/12

x < -3/2

Then solve the other inequality

5x−8>40

Add 8 to each side

5x-8+8>40+8

5x>48

Divide each side by 5

5x/5 >48/5

x > 9  3/5

Put them back together with the OR in the middle

x < -3/2 OR x > 9  3/5

Write the sentence as an equation The product of -2 and -30 gives 60
slega [8]

<em><u>The equation for the product of -2 and -30 gives 60 is:</u></em>

-2 \times -30 = 60

<em><u>Solution:</u></em>

Given that, The product of -2 and -30 gives 60

We have to write the sentence as equation

It includes operations such as addition, subtraction, multiplication and division.

From given statement,

The product of -2 and -30 gives 60

Here, "product" means multiplication

Therefore, -2 multiplied with -30 gives 60

Which is written as equation as,

-2 \times -30 = 60

Thus the given sentence is translated into equation

Answer: Circle.

Depending on the angle and the place of intersection, when a plane intersects a cube, the sections created may be a square, a pentagon, a trapezoid, a triangle or a rectangle (even you can obtain an octagon), but you will never get a circle.

Given the regular octagon shown below, what is the measure of angle x?
vladimir1956 [14]

Answer:

x=45°

Step-by-step explanation:

The angle shown in the figure is known as an external angle.

Also, <u>in a regular polygon (like the regular octagon) the sum of all the exterior angles is the same regardless of the number of sides of the figure</u>:

360°

And to find the measure of a single external angle (such as the angle x shown in the figure) we must <u>divide 360 ° by the number of sides n:</u>

\frac{360}{n}

and for the regular octagon, since it has 8 sides:

n=8

so the value of x is:

x=\frac{360}{n}\\ \\x=\frac{360}{8}\\ \\x=45°

the measure of angle x is 45° which is the second option
