Answer:

x = 3.333333333

Step-by-step explanation:

Solve for x by simplifying both sides both sides, then isolating the variable.

-\frac{1}{2} x+2=x+7

                          -2    -2

-\frac{1}{2} x=x+5

                  *2        *2

x+2x=+10

      -2x    -2x

-3x=10

x=-\frac{10}{3}

x = -3.3333333

What is the final amount if 943 is decreased by 13% followed by a further 6% decrease?
kipiarov [429]

Answer:

771.18

Step-by-step explanation:

The Amount given is  943

13% of amount will be =  943 x 13%

                         =

Decreasing 13% from 943 we get = 943-122.59

                        =820.41

Now the ammount = 820.41

for finding the final amount

find 6% of amount (820.41) we get =  820.41x 6%

                               =

Decreasing 6% from 820.41 we get final amount= 820.41- 49.23

                                   =771.18

so the final amount is 771.18
