Answer:

75

Step-by-step explanation:

If the third of 6 consecutive numbers is 12, what is their sum?

6 numbers = c-2, c-1, c, c+1, c+2, and c+3

The numbers become 10, 11, 12, 13, 14, and 15

Add that together and you get 75.

How much water do you add...

Alecsey [184]

Answer: 36.67 grams of water is added.

Step-by-step explanation:

Let the amount of water is added be 'x'.

Amount of sugar = 5 g

We need to make 12% of sugar syrup.

x grams of water is added to 5 g of sugar, to 12% of sugar syrup.

so, it becomes,

$\frac{5}{5+x}=\frac{12}{100}\\\\100\times 5=12(5+x)\\\\500=60+12x\\\\500-60=12x\\\\440=12x\\\\\frac{440}{12}=x\\\\36.67\ g=x$

Hence, 36.67 grams of water is added.

let x=k

D=dog

T=Taxes

I=increase P=population

solve k

d=23,000

t=2000

d=2.3e^

divide both sides by 2

after year is,2000+k2-2.3

=1.999.7

k2- 23,000=

k-x

or
