Answer:

$x=-64$

Step-by-step explanation:

$\frac{x}{4} -16=-32$

Add 16 to both sides.

$\frac{x}{4} -16+16=-32+16$

Simplify.

$\frac{x}{4} =-16$

Multiply both sides by 4.

$\frac{4x}{4} =4(-16)$

Simplify.

$x=-64$

Step-by-step explanation:

The given sequence is Arithmetic Progression.

Arithmetic Progression is a sequence in which every two neighbor digits have equal distances.

Here first we will find the number of terms

For finding the nth term, we use formula

aₙ = a + (n - 1) d

where, aₙ = value of nth term

a = First term

n = number of term

d = difference

Now, In given sequence: 12, 22, 32, 42, ⋯ , 100002

a = 12, d = 10, n = ? and aₙ= 100002

∴ 100002 = 12 + (n - 1) × (10)

⇒ 99990 = 10(n - 1)

⇒ n = 10000

Now using the formula of Sum of Arithmetic Sequence,

Sₙ = n÷2[2a + (n - 1)d]

⇒ Sₙ = (10000÷2)[2 × 12 + 9999 × 10]

⇒ Sₙ = 5000 [ 24 + 99990]

⇒ Sₙ = 5000 × 100014 = 50,00,70,000

The population of Weston is 4320. The town’s records show that 45 percent of the population are males, and 2 3 23 of these males

lbvjy [14]

Answer:

In Weston 1,296 males are married

Step-by-step explanation:

step 1

Find out the number of males

Multiply the total population by 45%

$45\%=45/100=0.45$

$4,320(0.45)=1,944\ males$

step 2

Find out the number of males that are married

Multiply the number of males by 2/3

$\frac{2}{3}(1,944)=1,296\ males\ married$

therefore

In Weston 1,296 males are married
