The equatonJ4x2425X-47 ax-4--**-3-53 ax-2 IS truefor all value syĂ#2 a,where a ls a (onstant.what is We Value ě d? |
|
Answer» multiply both sides of the given equation byax−2. When you multiply each side byax−2, you should have: 24x2+25x−47=(−8x−3)(ax−2)−53 You should then multiply (−8x−3) and (ax−2) using FOIL. 24x2+25x−47=−8ax2−3ax+16x+6−53 Then, reduce on the right side of the equation 24x2+25x−47=−8ax2−3ax+16x−47 Since the coefficients of thex2-term have to be equal on both sides of the equation, −8a=24, ora=−3. so answer is -3 Thank you |

Find the least number that should be subtracted from 1000 so that 35 dividesthe difference exactly. |
|
Answer» According to Euclid's division algorithm, a=bq+r Where, a= dividend b=divisor q=quotient And r=remainder. So let a=1000, b=35, So we get, 1000= 35×28+20Subtracting 20 from both sides, 1000–20=35×28+20–20 Thus, 980=35×28 Therefore, as seen above,980 is perfectly divisible by 35. And so,20 is the smallest number to be subtracted. |

3306. If the price of 3 pens, 2 pencils and4 erasers is 92 and the price of8 pencils and 16 erasers is P68, thenthe price of 24 pens is(1) P675(2) P625 |
|
Answer» We know that 8 pencils + 16 erasers are equal to 68 rupees Now we will divide it by 4 And then 2 pencils + 4 erasers are equal to 17 rupees Now we will find the cost of 3 pens And for that we will use this formula Cost of 3 pens + 17 is equal to 92 rupees Cost of 3 pens is equal to 75 rupees Cost of 1 pen is equal to 25 rupees Now in order to find the price of 24 pens 25 x 24 = 600 So the final answer for this question is 600 |

|
Answer» 1)the L.C.M of 8,9,10 is 360 now 360 = 2*2*2*3*3*5here 2 and 5 are not in pair to make the number a perfect square so, multiply 360 with 2 and 5 the number is 360*10 = 3600 2) 4,6,10,18 The L.C.M is 180 so, 180 = 2*2*3*3*5 so, there only 5 is needed to be multiplied to make the number a perfect square..so, the number is 180*5 = 900 |
