One-third of a number added to itself equals 3 times the difference of the number and seven.

Mathematics

olya-2409 [2.1K]3 years ago
3 0

Answer:

Step-by-step explanation:

Do this step by step.

Let the number = x

1/3 of a number = 1/3 x

Added to itself 1/3x + x

=

3*(x - 7)

So the equation is

1/3x  + x = 3(x - 7)            Remove the brackets. Collect 1/3x and x

4/3 x = 3x - 21                 Multiply both sides by 3.

4x = 3*(3x - 21)                Remove the brackets again

4x = 9x - 63                    Subtract 9x from both sides

-5x = -63                         Divide by -5

x = -63/-5

x = 12.6

HELP ASAP PLSSSSSSSSSSSS
ludmilkaskok [199]

Answer:

f = .39

Step-by-step explanation:

d (v) = 2.15 v^2 / (64.4 f)

v = 40

d = 138

substitute these in

138 = 2.15 (40)^2 / (64.4 *f)

simplify

138 = 2.15 (*1600) / (64.4 *f)

138 = 3440 / (64.4 *f)

multiply each side by 64.4f

138 * 64.4 f = 3440

8887.2 f = 3440

divide by 8887.2

8887.2 f /8887.2= 3440/8887.2

f=.38707

to the nearest hundredth

f = .39

Musya8 [376]

Answer:

Volume=1232cm Surface area=660cm

Step-by-step explanation:

Volume=π x r² x t

=22/7 x 7 x 7 x 8

=1232cm

Surface area=2 x π x r x (r+t)

=2 x 22/7 x 7 x (7+8)

=44 x 15

=660cm

On a coordinate plane, triangle R S T has points (0, 4), (0, negative 2), and (3, negative 2).
ziro4ka [17]

The values gotten for the  coordinate plane are;

  • The distance between the x-coordinate of R and T is 3.
  • The distance between the y-coordinate of R and T is 6.
  • R' is (-1, 2) from T, so the coordinates of R' are (2, 0).

<h3>Why the above values?</h3>

The Reason for the obtained value is that since thee rule for the dilation of ΔRST is:

  • The vertices of the given triangle are R(0, 4), S(0, -2), T(3, -2)

Then, the distance that exist between the x-coordinate of R and T will be:

3 - 0

= 3

Then the distance between the y-coordinate of R and T will be:

4 - (-2)

= 6

Note that the location of the point R' is said to be relative to point T and as such:

The location of point R'

= (-1 + 3, 2 - 2)

= R'(2, 0)

Hence R' is (-1, 2) from T, and the coordinates of R' is (2, 0)

Therefore, The values gotten for the  coordinate plane are;

  • The distance between the x-coordinate of R and T is 3.
  • The distance between the y-coordinate of R and T is 6.
  • R' is (-1, 2) from T, so the coordinates of R' are (2, 0).
