Solve set in roster (Tabular) from {x:x = n/n+2 ; n€N and n>5 }

Answer»

Answer:

A{1/2 , 2/3 , 3/4 , 4/5}

Step-by-step EXPLANATION:

Given Set FORM:

{X : x = n/n+2 ; n belongs to Natural number and n<5}

Here it clears that,

x = n/(n+2)

where n = 1 , 2 , 3 , 4

a) x=1/1+1

x = 1/2

b) x=2/2+1

x = 2/3

c) x = 3/3+1

= 3/4

d) x = 4/4+1

x = 4 / 5

So the Roaster form of the set is

A{1/2 , 2/3 , 3/4 , 4/5}

Hope it helps you,

8m+4= 3(m-1)can anyone please solve this

Answer»

ANSWER:

Simplifying

8m + 4 = 3(m + -1) + 7

Reorder the terms:

4 + 8m = 3(m + -1) + 7

Reorder the terms:

4 + 8m = 3(-1 + m) + 7

4 + 8m = (-1 * 3 + m * 3) + 7

4 + 8m = (-3 + 3m) + 7

Reorder the terms:

4 + 8m = -3 + 7 + 3m

Combine LIKE terms:

-3 + 7 = 4

4 + 8m = 4 + 3m

Add '-4' to each side of the equation.

4 + -4 + 8m = 4 + -4 + 3m

Combine like terms: 4 + -4 = 0

0 + 8m = 4 + -4 + 3m

8m = 4 + -4 + 3m

Combine like terms: 4 + -4 = 0

8m = 0 + 3m

8m = 3m

Solving

8m = 3m

Solving for VARIABLE 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-3m' to each side of the equation.

8m + -3m = 3m + -3m

Combine like terms:

8m + -3m = 5m

5m = 3m + -3m

Combine like terms: 3m + -3m = 0

5m = 0

Divide each side by '5'.

m = 0

Simplifying

m = 0

Find the missing number 15 42 122 ____ 1077 3224PLEASE ANSWER FAST! SPAMS WILL BE REPORTED

Answer»

Multiply only by 3 and subtract in ascending ORDER starting from 3 from every digit.

Step-by-step explanation:

15:- (15×3) - 3 = 42

42:- (42×3) - 4 = 122

122:- (122×3) - 5 = 361

361 :- (361×3) - 6 = 1077

1077:- (1077×3) - 7 = 3224

Answer» Given that the smallest number when divided by 28 and 32 leaves REMAINDER 8 and 12 respectively. 28 - 8 = 20 and 32 - 12 = 20 are divisible by the REQUIRED numbers. Therefore the required number will be 20 less than the LCM of 28 and 32. Prime FACTORIZATION of 28 = 2 * 2 * 7 Prime factorization of 32 = 2 * 2 * 2 * 2 * 2 LCM(28,32) = 2 * 2 * 2 * 2 * 2 * 7 = 224. Therefore the required smallest number = 224 - 20 = 204. Verification: 204/28 = 28 * 7 = 196. = 204 - 196 = 8 204/32 = 32 * 6 = 192 = 204 - 192 = 12.

Find the smallest no such that when it is divided by 28,38,63 leaves remainder 18,28,38 respectively

Answer»

Given that the smallest number when divided by 28 and 32 leaves REMAINDER 8 and 12 respectively.

28 - 8 = 20 and 32 - 12 = 20 are divisible by the REQUIRED numbers.

Therefore the required number will be 20 less than the LCM of 28 and 32.

Prime FACTORIZATION of 28 = 2 * 2 * 7

Prime factorization of 32 = 2 * 2 * 2 * 2 * 2

LCM(28,32) = 2 * 2 * 2 * 2 * 2 * 7

= 224.

Therefore the required smallest number = 224 - 20

= 204.

Verification:

204/28 = 28 * 7 = 196.

= 204 - 196

= 8

204/32 = 32 * 6 = 192

= 204 - 192

= 12.
