How to Find x value: 9-0.75(x+8)-5=-6.5

Mathematics
1 answer:
Dahasolnce [82]3 years ago
8 0
Here's how to find the value of x:

<span>9 - 0.75 ( x + 8 ) - 5 = -6.5      find the difference of 9 - 0.75

</span><span>8.25 ( x + 8 ) - 5 = -6.5           add 5 to both sides
</span>
8.25 ( x + 8 ) = -1.5                distribute 8.25 to x and 8

8.25x + 66 = -1.5                    subtract 66 from both sides

8.25x = -67.5                          divide both sides by 8.25

x = 18.18181818......            the value of x is 18 2/11

hope this helps

Alfredo's painting his storage shed. He won't paint the top or bottom of the shed so he needs to calculate the lateral surface a
slavikrds [6]

Answer:

He is not painting the bottom or top meaning that he will paint 4 sides total,   when there is a rectangular prism there are 6 sides and 3 pairs of 2 equal sides, so since there is a wall that is 9ft x 7 ft there is two of those, and since there is a wall that is 12 ft x 7 ft there are two of those as well. meaning that (7x9)·2=126 and (12x7)·2=168 when added we get 294. meaning that he needs to paint an area of 294 ft

3. What are the identification numbers for ten students chosen at random from a population of 78 students based on the following
Naya [18.7K]

Answer:

27 67 16 01 27 35 21 37 74 10

Step-by-step explanation:

Starting from the left, you pick two numbers together and skip two numbers if it is greater than 78.

Meaning:

27816 78416 01822 73521 37741 016312 68000 53645 56644 97892 63408 77919 44575

You pick [27] and leave 81 since it is greater than 78, the population number.

Then you pick [67] and leave 84 as it is also greater than 78.

Then you pick [16] and [01] but leave 82, as it is greater than 78.

Then pick [27], [35], [21], [37], [74] and [10] since they are all less than 78.

At this juncture, you have identified 10 numbers: 27 67 16 01 27 35 21 37 74 10

I need help fast with this! please (14 points)
sveta [45]

Answer:

<em>Part 1 : Equation: ( 3x - 9 ) + 30 + 24 = 180,</em>

<em>Part 2 : Value of x ⇒ 45°,</em>

<em>Part 3 : Measure of Angle U ⇒ 126°</em>

Step-by-step explanation:

~ Part 1 ~

We know that ∑ of angles in a triangle is 180;

m∠ U + m∠ V + m∠ W = 180°,

<em>Equation: ( 3x - 9 ) + 30 + 24 = 180</em>

~ Part 2 ~

Now let us simplify the equation above to solve for x;

3x - 9 + 30 + 24 = 180,

3x - 9 = 126,

3x = 135,

x = 45 degrees ( ° ) ⇒

<em>Value of x ⇒ 45°</em>

~ Part 3 ~

If it is known that m∠ U ⇒ 3x - 9;

m∠ U = 3 * ( 45 ) - 9,

m∠ U = 135 - 9,

m∠ U = 126 degrees ( ° ) ⇒

<em>Measure of Angle U ⇒ 126°</em>

Find sec Θ if the terminal side of Θ in standard position contains the point (4, -3)
CaHeK987 [17]
If we plot that point we find ourselves in QIV.  The distance along the x axis is 4, and the distance down from that point is -3.  If we create a right triangle with that segment, that segment serves as the hypotenuse of the triangle.  We need its measure.  Using Pythagorean's theorem, 4^2+-3^2=c^2 and 16+9=c^2.  We see that c = 5.  We need now to find the secant of that right triangle.  Secant if the co-identity of cosine which is side adjacent over hypotenuse.  That means that secant is the hypotenuse over the side adjacent.  So our secant theta = 5/4
