algebra applications: find the value of x and y ​

How many squares make up the surface of a cube?

O A. Seven

O B. Five

● C. Six

D. Eight

Answer:

Step-by-step explanation:

[tex]\frac{8x}{7}=8[/tex]

Multiply both sides by 7

[tex]7*\frac{8x}{7}=8*7\\\\8x=8*7\\[/tex]

Divide both sides by 8

[tex]\frac{8x}{8}=\frac{8*7}{8}\\[/tex]

x = 7

Answer:

-The value of [tex]x[/tex]:

[tex]x = 7[/tex]

Step-by-step explanation:

-Solve for the value of [tex]x[/tex]:

[tex]\frac{8x}{7} = 8[/tex]

-Multiply both sides by the denominator, which is [tex]7[/tex]:

[tex]7\cdot \frac{8x}{7} = 8 \cdot 7[/tex]

[tex]8x = 56[/tex]

-Divide both sides by 8:

[tex]\frac{8x}{8} = \frac{56}{8}[/tex]

[tex]x = 7[/tex]

So, the value of [tex]x[/tex], would be [tex]x = 7[/tex].

Answer:

[tex]\dfrac{\pi}{10}[/tex].

Step-by-step explanation:

All coterminal angles of an angle [tex]\theta[/tex] are defined as

[tex]\theta +2n\pi[/tex] or [tex]\theta + n360^{\circ}[/tex]

where, n is an integer.

The given angle is

[tex]\theta=-\dfrac{19\pi}{10}[/tex]

So, all coterminal angles of an angle [tex]\theta[/tex] are

[tex]-\dfrac{19\pi}{10}+2n\pi[/tex]

For n=1,

[tex]\Rightarrow -\dfrac{19\pi}{10}+2(1)\pi[/tex]

[tex]\Rightarrow -\dfrac{19\pi}{10}+2\pi[/tex]

[tex]\Rightarrow \dfrac{-19\pi+20\pi}{10}[/tex]

[tex]\Rightarrow \dfrac{1\pi}{10}[/tex]

Since,  [tex]\dfrac{\pi}{10}[/tex]  between 0 and 2π, therefore,  the required coterminal angle is [tex]\dfrac{\pi}{10}[/tex].

Answer:

40 adults and 140 kids

Step-by-step explanation:

40 adults

pairs of adults= 20

20 x 7kids= 140 kids

40 adults plus 140 kids = 180 total

Answer:

40 adults and 140 kids

Step-by-step explanation:

for every 9 people there are 2 adults and 7 kids

so if there are 180 people in total we would

180 / 9

180 / 9 = 20

so there are 20 groups of 2 adults and 7 kids

40 adults and 140 kids

Answer:

We have been given the equation: x+y+z. Now these are variables. Thus, we have to fill in the values given: where x = 18, y = 6 and z = 1. Let's fill these values in.

x+y+z

= 18+6+1

= 18+(7)

= 25

Hope it Helps. Good luck on your assignment! (brainliest if possible)

Answer:

[tex] = 25[/tex]

Step-by-step explanation:

[tex]x + y + z[/tex]

Given that,

[tex]x = 18 \\ y = 6 \\ z = 1[/tex]

Let's solve

[tex]x + y + z \\ 18 + 6 + 1 \\ 24 + 1 \\ = 25[/tex]

Value of blank 1 is 2

Value of blank 2 is 10

Step-by-step explanation:

We are given that a and b are the lengths of legs of right angle in right angled triangle .

b = 3

We are also given that c is the hypotenuse

c = hypotenuse = 7

To find the value of 'a' we will use Pythagoras theorem

[tex]Hypotenuse^2 = perpendicular^2 +base^2\\c^2=a^2+b^2\\7^2=a^2+3^2\\7^2-3^2=a^2\\\sqrt{7^2-3^2}=a\\\sqrt{40}=a\\2\sqrt{10}=a\\[/tex]

Value of blank 1 is 2

Value of blank 2 is 10

Step-by-step explanation:

2( a + 3)    if   (a = 3)

then now is 2( 3 + 3 )

3+3 = 6........6  times 2 = 12

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

❌: 2(3) = 2 x 3 = 6  ←← not 12

❌: 5(3) = 5 x 3 = 15 ←← not 12

❌: 2(3)+3 = 2 x 3 = 6.... 6 + 3 = 9 ←← not 12

✅: 2(3)+6 = 2 x 3 = 6.... 6 + 6 = 12 ←← its 12

The next three terms of the arithmetic sequence 5, 9, 13, 17 is 21, 25, 29.

Given that,

Based on the above information, we can see that

There is the addition of 4 in each next number i.e.

5 + 4  = 9

9 + 4 = 13

13 + 4 = 17

17 + 4 = 21

21 + 4 = 25

25 + 4 = 29

Therefore, the option d is correct

Hence, the other options are incorrect.

Therefore we can conclude that the next three terms of the arithmetic sequence 5, 9, 13, 17 is 21, 25, 29.

Answer:

y = x + 4

I graphed all the points, and the line that goes through AB is y = x - 6. The bases of a trapezoid are parallel, so the slope on the line CD has to be the same. I graphed the point C and just tried different y-intercepts to see which line would go through C.

Answer:

251.2 m

Step-by-step explanation:

Circumference = 2 x π x r

C = 2 x 3.14 x 40

C = 251.2

Circumference of a circle

The path or the boundary that encircles any shape is defined by its circumference. In other words, the perimeter is another name for the circumference, which makes it easier to determine how long a shape's outline is. The circle's perimeter is measured in this way. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it.

We take radius of the circle and pi to calculate the circumference of circle.

The formula of circumference of circle is 2πr.

R is radius of the circle and π is mathemetical constant which value approx 3.14

In the question it is given that the diameter of a wheel is 80m. So, radius is half of diameter, 40m.

So, the circumference = 2πr

                                     = 2 × 3.14 × 40 = 251.2m

Rider has to travel 251.2m to cover one complete rotation.

Answer:

The top of the ladder touches the tree 14 ft above the ground.

Step-by-step explanation:

The Pythagorean Theorem incorporates the ladder length (17.5 ft), the distance of the base of the ladder from the base of the tree (10.5 ft), and the point where the ladder touches the tree (x ft):

x^2 + 10.5^2 = 17.5^2, or

x^2 + 110.25 = 306.25.  Then x^2 = 196, and x = +14  (Answer C)

The top of the ladder touches the tree 14 ft above the ground.
