11x + 15y = -23 ---- (1) ////// 7x - 2y = 20 ---- (2). Take equation (2). Thus, x = 20 + 2y / 7// ---- (A). Equating (A) to (1), we get :- 11 (20 + 2y / 7) + 15y = -23 => 220 + 22y / 7 + 15y = -23 => 220 + 22y + 105y = -161 => 127y = -161 - 220 => 127y = -381 => y = -3// Therefore, x = 20 + 2y / 7 = 20 - 6 / 7 = 14 / 7 = 2//

Use euclid s algorithm to find the HCF of 4052 and 12576

Posted by Snowie Bakshi 4 years, 6 months ago (10737295)

CBSE > Class 10 > Mathematics

1 answers

Preeti Dabral 4 years, 6 months ago (2983787)

According to Euclid’s Division Lemma if we have two positive integers a and b, then there exist unique integers q and r which satisfies the condition a = bq + r where 0 ≤ r ≤ b.

HCF is the largest number which exactly divides two or more positive integers.

Since 12576 > 4052

12576 = (4052 × 3) + 420

420 is a reminder which is not equal to zero (420 ≠ 0).

4052 = (420 × 9) + 272

271 is a reminder which is not equal to zero (272 ≠ 0).

Now consider the new divisor 272 and the new remainder 148.

272 = (148 × 1) + 124

Now consider the new divisor 148 and the new remainder 124.

148 = (124 × 1) + 24

Now consider the new divisor 124 and the new remainder 24.

124 = (24 × 5) + 4

Now consider the new divisor 24 and the new remainder 4.

24 = (4 × 6) + 0

Reminder = 0

Divisor = 4

HCF of 12576 and 4052 = 4.

There are generally two types of blood flowing through the human body namely :- 1) OXYGENATED BLOOD = Blood which is abundant in oxygen. This blood enters the Left atrium of the heart and is then passed on to Left Ventricle from where it is pumped to other cells. 2) DEOXYGENATED BLOOD = Blood abundant in carbon dioxide. Enters right atrium then into right ventricle and finally pumped to lungs for purification.

According to science viruses come in the category of both living and non living. But mainly they are active when they are inside our body. That's bcs when they are outside the body of host then they can't do their reproduction but when they come in the host body then they start to do reproduction in large amount. So,they are active inside the host's body
