Answer» Answer: => Z = - 19/ 40 is the answer. Step-by-step explanation: Z-7/3-z-5/12=2z-27/15 => z - z -7/3 -5/12 = 2z -27/15 => (z - z) + (-7/3 -5/12) = 2z -27/15 => 0 - (7/3 + 5/12) +27/15 = 2z => - [(7x 4)/(3X4) + 5/12) +27/15 = 2z => - [28/12 + 5/12) +27/15 = 2z => - [(28+5)/12) +27/15 = 2z => - 33/12 +27/15 = 2z => 2z = - 33/12 + 27 /15 => 2z = - (33 x 5)/(12x 5) + (27 x 4)/ (15 x 4) => 2z = - 165/60 + 108/ 60 => 2z = (- 165+ 108)/ 60 => 2z = - 57/ 60 => z = - 57/ (60 x 2) => z = - 57/ 120 => z = - 19/ 40

21.

Z-7/3-z-5/12=2z-27/15

Answer»

Answer:

=> Z = - 19/ 40 is the answer.

Step-by-step explanation:

Z-7/3-z-5/12=2z-27/15

=> z - z -7/3 -5/12 = 2z -27/15

=> (z - z) + (-7/3 -5/12) = 2z -27/15

=> 0 - (7/3 + 5/12) +27/15 = 2z

=> - [(7x 4)/(3X4) + 5/12) +27/15 = 2z

=> - [28/12 + 5/12) +27/15 = 2z

=> - [(28+5)/12) +27/15 = 2z

=> - 33/12 +27/15 = 2z

=> 2z = - 33/12 + 27 /15

=> 2z = - (33 x 5)/(12x 5) + (27 x 4)/ (15 x 4)

=> 2z = - 165/60 + 108/ 60

=> 2z = (- 165+ 108)/ 60

=> 2z = - 57/ 60

=> z = - 57/ (60 x 2)

=> z = - 57/ 120

=> z = - 19/ 40

Y3–8 by y–2 by long division method

Answer»

we get QUOTIENT = (y² + 2y + 4) and REMAINDER = 0

we have to divide (y³ - 8) by (y - 2) by long DIVISION method.

y - 2) y³ - 8. (y² + 2y + 4

y³ - 2y²

............................

2y² - 8

2y² - 4y

0

hence when (y³ - 8) is divided by (y - 2) , quotient = (y² + 2y + 4) and remainder = 0.

also read similar questions: IF x + y + 2 = 0, then WRITE the value of x3 + y3 + 8

34.	A' s income is 25% more then that of B . What percent is B's income less than A's ??plz solve fast
Answer» Answer: Let the INCOME of B be 100. Given that A's income is 25% more than that of B. ⇒ Income of A = 100 + 25% of 100 = 100 + (25/100) * 100 = 125. Now,It clearly SHOWS that B's income is LESS than that of A by 25. ⇒ % of B = (25/125) * 100% = (1/5) * 100% = 20%. Therefore, B's income is 20% less than A's income. Hope it helps!

34.

A' s income is 25% more then that of B . What percent is B's income less than A's ??plz solve fast

Answer»

Answer:

Let the INCOME of B be 100.

Given that A's income is 25% more than that of B.

⇒ Income of A = 100 + 25% of 100

= 100 + (25/100) * 100

= 125.

Now,It clearly SHOWS that B's income is LESS than that of A by 25.

⇒ % of B = (25/125) * 100%

= (1/5) * 100%

= 20%.

Therefore, B's income is 20% less than A's income.

Hope it helps!
