3x÷2_5y÷3=_2 x÷3+y÷2=13÷6 solve this by substitution

Answer»

Answer:

☑ 3x / 2 - 5y/3 = -2

(9x - 10y)/6 = -2

9x - 10y = - 12 ..........(1)

☑ x /3 + y /2 = 13/6

(2x +3Y)/6 = 13/6

2x + 3y = 13...............(2)

x = (13 - 3y) /2

put this value of x in EQUATION (1)

9((13 - 3y) /2 ) - 10y = - 12

(177 - 27Y )/ 2 ) - 10y = -12

177 - 27y - 20y = -24

177- 27y = -24

- 27y = -24- 177

-27y =- 201

y = -201/-27

y = 67 / 9

put this value of y in equation (2)

2x + 3 ( 67/9) = 13

((2x) x 9)+ 201= 13 x 9

18x = 177 - 201

18x = - 24

x = -24 /18

x =- 8/6 = 4 / 3

x =- 4/3

Greatest and smallest 7 digit number using 35712

Answer»

ANSWER:

Greatest: 75321

Smallest: 12357

Step-by-step explanation:

Greatest

The first digit is always the largest in value, COMPARED to the last few(Example 30000 is always bigger than 3 at the back- which is just 3)

Hence, always put larger digits at the front to obtain a bigger number.

Smallest

Likewise for SMALLER digits, it's just the opposite, put small digits at the front than back because digits at the front have a greater value than digits at the back.

Hope all goes well. Cheers!

Answer»

Step-by-step explanation:

for ascending order

-20<-16<-13<-12<-10<25 <30<31

for descending order

21,18,15,12,0,-3,-8,-11

now (a+b)=-5 such as order are

(0,-5);(-5,0);(10,-15);(-10,5);(-12,7)

now a.b=60

(10,6);(6,10);(-6,-10);(-10,-6);(12,5)

now a-b=7

(8,1);(9,2);(10,3);(11,4);(12,5)

Mrs. sinah is 150 cm tall and her son is2/5 as she is find height of her son​

Answer»

\mathfrak{\large{\underline{\underline{Answer :-}}}}

The Son's height is 60 cm.

\mathfrak{\large{\underline{\underline{Explanation :-}}}}

Given :

MRS. SINHA's Height = 150 cm

Her son's height = \tt{\dfrac{2}{5}} of Mrs. Sinha's height

To Find :

The Son's height

Solution :

We need to find the \tt{\dfrac{2}{5}} of Mrs. Sinha's height.

{\boxed{\sf{\dfrac{2}{5}\:of\:150}}}

\tt{\implies} \:  \dfrac{2}{5}  \: of \: 150

\tt{\implies} \:  \dfrac{2}{\cancel5}  \:  \times  \: \cancel{150}

\tt{\implies} \: 2 \times 30

\tt{\implies} \:60

\therefore The Son's height is 60 cm.
