45% of the population of a city are men

leonid [27]

Answer:

$\boxed{\textsf{ The number of children is \textbf{24150}.}}$

Step-by-step explanation:

Given that the 45% of the population of a city are men and 15% are children . The number of women is 64,400 . And we need to find the number of children . Here ,

$\sf\implies Percentage_{(men)}= 45/% .\\\\\sf\implies Percentage_{(children)}= 15\% .$

So the percentage of women will be equal to [ 100 - ( 45 -15) ]% = [ 100 - 60 ]% = 40% .

So let us take the total number of people be x . So ,

$\purple{\bigstar}\underline{\underline{\boldsymbol{ According\ to \ Question :- }}}$

$\sf\implies 40\% \ of \ x \ = \ 64,400 \\\\\sf\implies \dfrac{40x}{100}= 64,400 \\\\\sf\implies x =\dfrac{64,400\times 100}{40}\\\\\sf\implies \boxed{\pink{\sf x = 161,000 }}$

$\rule{200}2$

The percentage of children = 15% :-

$\sf\implies Number_{(children)}= 15\% \ of 161,000\\\\\sf\implies Number_{(children)}= \dfrac{15}{100}\times 161,000 \\\\\sf\implies \boxed{\pink{\frak {Number_{(children)}= 24150 }}}$

Find the value of r so the line that passes through the pair of points has the given slope.

SOVA2 [1]

Answer:

The missing value in the ordered pair is 66

Step-by-step explanation:

Given that:

(12,10) and (-2,r)

Slope = m = -4

We have to find the value of r so that the line has a slope of -4.

Slope is the steepness of line which is denoted by m.

Here,

$x_1=12, y_1=10\\x_2=-2, y_2=r$

Putting the values in slope of line formula,

$-4=\frac{r-10}{-2-12}\\ -4=\frac{10-r}{-14}\\$

Multiplying both sides by -14

$-4*-14=\frac{r-10}{-14}*-14\\56=r-10\\56+10=r\\66=r\\ r=66$

The value of r is 66

Hence,

The missing value in the ordered pair is 66

Lloyd solves the equation 24x + 18(x – 2) = 216 for x. Some of his steps are shown.

Elena-2011 [213]

Answer:

Hi there!

Your answer is:

To get from step 3 to step 4, Lloyd added 36 to both sides. On the left side, this equaled 0 due to the additive inverse property! (-36 + 36 = 0!) On the right side, 36 is added to 216! (216+36 = 252)

M is between N and O. Find NO. NM = 17 MO = 3x - 5 NO = 5x + 2

Sonbull [250]

NM + MO = NO
17 + 3x - 5 = 5x + 2
Combine like terms (17 - 5)
12 + 3x = 5x + 2
Subtract 3x from both sides (3x - 3x) (5x - 3x)
12 = 2x + 2
Subtract 2 from both sides (2 - 2) (12 - 2)
10 = 2x
Divide 2 from both sides (2/2) (10/2)
X = 5

NO = 5x + 2
NO = 5(5) + 2
NO = 25 + 2
NO = 27
