.............. .......

Answer:

Make x the same in both so

12x+ 4y=72

12x+6y=30

Now the 12x cancel eachother out so

Difference between 6y and 4y is 2y

Difference between 30 and 72 is -42

2y must equal -42

Y = -21

Substitute -21 into the equation

X = 13

Answer: 4x, 2x+2x, x+x+x+x

Step-by-step explanation: all are the same expresions.

Answer:

x = 1

Step-by-step explanation:

If x and 2 are in proportion and x+2 and 6 are in proportion, we can make them equal. We can do that by doing:

[tex]\frac{x}{2} = \frac{x+2}{6}[/tex]

After cross-multiplying, we get 2x+4 = 6x.

Subtract 2x on both sides and we get 4 = 4x

divide 4 on both sides and we get x = 1

The value of x is equal to 1.

The quantitative relation between two amounts showing the number of times one value contains or is contained within the other. for example-"the ratio of computers to students is now 2 to 1"

Given here, x, 2, x+2, 6 are in proportion, then we have

x/2=x+2/6

x   = 1

Hence, The value of x is equal to 1.

Answer:

[tex] \frac{5}{6} [/tex]

[tex]v = \frac{4}{3} \times \pi \times {r}^{3} [/tex]

Finding the radius,

[tex]d = 2r, \: r = \frac{d}{2} = \frac{8}{2} = 4inches[/tex]

Plugging in our values,

[tex]v = \frac{4}{3} \times 3.14 \times {4}^{3} = \frac{4}{3} \times 3.14 \times 64 = 267.95 {inches}^{3} \\ [/tex]

Rounding to the nearest whol number,

[tex]v = 268 {inches}^{3} [/tex]

Answer:

[tex]108\pi[/tex] inches³

Step-by-step explanation:

Hi there!

[tex]V=\frac{1}{3} \pi r^2h[/tex] where r is the radius and h is the height

Plug in the given values (r=6, h=9)

[tex]V=\frac{1}{3} \pi (6)^2(9)\\V=\frac{1}{3} \pi (36)(9)\\V=\frac{1}{3} \pi (324)\\V=108\pi[/tex]

Therefore, the volume of the cone is [tex]108\pi[/tex] inches³.

Step-by-step explanation:

The unknown side is part of the 90 degree angle, so it is not the hypotenuse.

Using the Pythagorean theorem:

x = sqrt(14^2 - 10^2)

x = sqrt(196-100)

x = sqrt(96)

Answer:

If Pam surveys 12 more students, than  four of them should she expect to pick English their favorite, based on past data.

Step-by-step explanation:

Probability means possibility of  occurrence. It is a branch of mathematics which deals with the occurrence of particular event out of some  random events.

Out of 18 students 6 have English as their favorite

Therefore the  possibility expected is [tex]\frac{6}{18}[/tex] = [tex]\frac{1}{3}[/tex]

which mean out of 3 student one will choose English  as favorite.

Thus if Pam surveys 12 more students then 12/3 = 4 .

Thus Four of them should expect to pick English their favorite, based on past data.
