find a number such that when 3/4 of it is added to 3.5 the sum is the same as when 2/3 of it is subtracted from 6.5

Lilit [14]

Answer:

2.1

Step-by-step explanation:

let unknown number be x

3/4x + 3.5= 6.5 - 2/3x

collect like terms

3/4x+2/3x=6.5 - 3.5

17/12x = 3

cross multiply

12 * 3=17x

36=17x

x=36/17

x=2.1

No, your answer are wrong (I assume that the question asks to simplify the roots). You can only remove (their square is placed in from of the root and multiplied by it) the numbers from the root that are squares, the lest must stay, like this:

$\sqrt{14} = \sqrt{2*7} ,$ no roots are among the factors, nothing can be removed
$\sqrt{14} = \sqrt{2*7} ,$ nothing can be removed
$-\sqrt{39} = -\sqrt{3*13}$ nothing can be removed
$-\sqrt{56} = -\sqrt{2*2*2*7}=-2\sqrt{14} ,$
$-\sqrt{77} = -\sqrt{11*7} ,$ nothing can be removed
$\sqrt{41} = \sqrt{41} ,$ nothing can be removed
$\sqrt{21} = \sqrt{3*7} ,$ nothing can be removed
$- \sqrt{65} = -\sqrt{5*13} ,$ nothing can be removed
$-\sqrt{12} = -\sqrt{2*3*4} =-2\sqrt{4},$
$\sqrt{13} = \sqrt{13} ,$ nothing can be removed
$\sqrt{32} = \sqrt{4*4*2} =4\sqrt{2},$
$\sqrt{47} = \sqrt{47} ,$ (47 is prime) nothing can be removed
$-\sqrt{99} = -\sqrt{9*11}= -3\sqrt{11} ,$

Find the sum of the value of 8 in 387,562 and the value of 7 in 7,328,562

MAXImum [283]

387,562
The 8 is in the ten thousands place, so it equals 80,000.

7,328,562
The 7 is in the millions place, to it equals 7,000,000.

The sum is the value of two numbers added together (the answer to an addition problem).

80,000 + 7,000,000 = 7,080,000
