Answer:

. With each 9s fact you add another 9, which means you go straight down a row and back one space. This creates a diagonal pattern in the grid.

Step-by-step explanation:

The number 99 is divisible by 9 . The number 999 is divisible by 9 , and so on. Any number that is a string of nines is divisible by 9 as it is 9 multiplied by a string of ones. This adds one to the sum of its digits, but you wind up with a number one more than a multiple of 9.

The ages of 3 brothers are represented by consecutive integers. If the oldest brother's age is decreased by twice the younger br

ANEK [815]

Answer:

The age of youngest brother is <u>21</u>.

Step-by-step explanation:

Given:

The ages of 3 brothers are represented by consecutive integers.

If the oldest brother's age is decreased by twice the younger brother's age, the result is -19.

Now, to find the age of youngest brother.

Let the age of youngest brother be $a-1.$

Let the age of middle one be $a$ .

And the age of oldest brother age be $a+1.$

According to question:

$(a+1)-2(a-1)=-19$

⇒ $a+1-2a+2=-19$

⇒ $-a+3=-19$

Adding $a$ on both sides we get:

⇒ $2=-19+a$

Adding 19 on both sides we get:

⇒ $22=a$

Now, getting the age of youngest brother by putting the value of $a$ :

$a-1$

⇒ $=22-1=21.$

Therefore, the age of youngest brother is 21.

Ooooooooof I need help

Answer:

a) x = -1 and y = -10

Step-by-step explanation:

The first part says find the value of y when the value of x is -3. Then the second part of the question is to find the value of x when the value of y is 2.

so lets solve part a)

$y=6x+8\\y=6(-3)+8\\y=-18+8\\y=-10\\\\Now\ when\ y=2\ find\ x\ \\y=6x+8\\2=6x+8\\2-8=6x\\-6=6x\\-6/6=x\\-1=x\\$

So answer to part a is x = -1 and y = -10

similarly try the other parts.
