One-fifth of a number is 14. Find the number

2 answers:

5 0

I think it would be 70 but i could be wrong.But how I did it was put an "x" on the left so that would be 1/5 * x okay? so then x=14 because we need to find the number so that's why "x" is there. so then since 1/5 is division we multiply. so when we do that on the side that has the 1/5 the 5 cancels out and then we just have 1x or x, so next we multiply 5 by 14 giving us 70! Hope this helps and tell me is it is correct?

$\frac{1}{5}$ × X = 14
x=14×5
x=70
So 70 is your answer

(x-4)/5=9-(2x-41)/9

For this question, you have to take Least Common Multiplier for which in this case will be "45" as, the denominators can get similar and get multiplied by a same value to form a similar expression. This allows us to cancel out them by common factors. Full process shown below.

$\mathbf{Given \: \: Expression: \: \dfrac{x - 4}{5} = 9 - \dfrac{2x - 41}{9}}$

$\mathbf{\dfrac{x - 4}{5} \times 45 = 9 \times 45 - \dfrac{2x - 41}{9} \times 45}$

$\mathbf{9(x - 4) = 405 - 5 (2x - 41)}$

$\mathbf{9x - 36 = 405 - 10x + 205}$

$\mathbf{9x - 36 = - 10x + 610}$

$\mathbf{9x - 36 + 36 = - 10x + 610 + 36}$

$\mathbf{9x = - 10x + 646}$

$\mathbf{9x + 10x = - 10x + 646 + 10x}$

$\mathbf{19x = 646}$

$\mathbf{\dfrac{19x}{19} = \dfrac{646}{19}}$

$\mathbf{\therefore \quad x = 34}$

$\boxed{\mathbf{\underline{\therefore \quad Final \: \: Answer \: \: is; \: \: x = 34}}}$

Hope it helps.

On a shelf containing 53 comic books, 21 are Marvel titles, 17 are DC titles, 12 are Dark Horse titles, and 3 are Harvey titles.

Answer:

68% or $\frac{36}{53}$

Step-by-step explanation:

In order to find the probability of Geraldo selecting a comic that isn't a DC title, we have to subtract the amount of comics that are DC titles from the total amount of comics and then divide that number by the total amount of comics.

53 - 17 = 36

36/53 = 0.679

Geraldo has a 68% chance of choosing a comic that isn't a DC title.

5p - 14 = 8p + 4 Explain

grigory [225]

1: we bring all the x to one member, changing its sign (I use x, consider it a p)
$5x - 8x - 14 = + 4$

2 we bring all the non-x to the other member
$5x - 8x = + 14 + 4$
3 we solve the members
$(5 - 8)x = - 3x$
$( + 14 + 4) = + 18$
4 we divide 18 by -3
$- 3x = + 18$
$x = 18 \div - 3$
$18 \div - 3 = - 5$
$x = - 5$

Someone please help me!

HACTEHA [7]

Answer:

B and C describe vertical angles

Step-by-step explanation:

Point R will be the common vertex of any possible pair of vertical angles.

For a given line segment, such as AE, one end will designate a side of one of the vertical angles, and the other end will designate a side of the other angle of the pair.

For example, Choice B uses the crossing segments TN and FL and identifies the vertical angles TRF and NRL.

Choice C uses segments FL and AE to identify the vertical angles LRE and FRA.

Choice A does not involve crossing segments. Choice D makes use of segment AE, but the other points S and N are not on the same segment.
