Answer:  The required value of the given expression is -57.

Step-by-step explanation:  We are given to find the value of the following expression :

E=7+32(-5+1)\div 2~~~~~~~~~~~~~~~~~~~~~~~~~~`(i)

We will be using the rule of BODMAS to solve the given problem.

From (i), we have

E\\\\=7+32(-5+1)\div 2\\\\=7+32(-4)\div 2\\\\=7-128\div 2\\\\=7-\dfrac{128}{2}\\\\=7-64\\\\=-57.

Thus, the required value of the given expression is -57.

Simplify both sides of the equation

  • 5x+2=244

Subtract 2 from both sides

  • 5x+2−2=244−2
  • 5x=242

Divide both sides by 5

\frac{5x}{5}  =  \frac{242}{5}

  • Answer

\: x =  \dfrac{242}{5}

OR

\: x =  48.4

The sum of two numbers is -17. Their difference is 41. Find the numbers.
Mnenie [13.5K]

Answer:

the two numbers are 12 and -29

Step-by-step explanation:

let the two numbers be x and y

let the sum of the two numbers b

x+y = -17 ..................................................... equation 1

let the difference between the two numbers be

x-y = 41 ........................................................................ equation 2

from equation 1

x+y = -17 ..................................................... equation 1

x = -17 - y ............................................................... equation 3

substitute for x in equation 2

x-y = 41 ........................................................................ equation 2

-17-y -y = 41

-17 -2y = 41

-2y = 41 + 17

-2y = 58

divide both sides by -2

-2y/-2 = 58/-2

y = -29

put the value of y = -29 in equation 3

x = -17 - y ............................................................... equation 3

x = -17-(-29)

x =-17 + 29

x = 12

therefore the two numbers are 12 and -29
