Answer:

False

Step-by-step explanation:

It is given that Noah thinks :

9x - 2x + 4x = 3x   as the subtraction sign after 9x tells us to subtract everything that comes after 9x.

This is wrong as according to the BODMAS rule, we have to do the addition operation first and then followed by subtraction operation.

That is

⇒ 9x - 2x + 4x

⇒ (9x -2x)+ 4x

⇒ 7x + 4x

⇒ 11x

Therefore the answer to the equation is 11x and not 3x.

The value of zlatans house has increased by 7% His house is now valued at ?749,000 Work out the value of the house before the in
wolverine [178]

Answer:

$440588.24

Step-by-step explanation:

Let x be the value of Zlatans house before the increase.

We are told that the value of Zlatans house has increased by 7%. His house is now valued at $749,000. This means that value of house(x) before increase plus 7% of x will be equal to $749000.

We can set this information in an equation as:  

x+\frac{70}{100}x=74900

x+0.7x=74900

Upon combining like terms we will get,

(1+0.7)x=74900      

1.7x=74900  

x=\frac{749000}{1.7}    

x=440588.2352941176470588\approx 440588.24      

Therefore, the value of the house before increase will be $440588.24.

The sales tax rate is 4.3064.306​% for the city and 44​% for the state. Find the total amount paid for 33 boxes of chocolates at
svp [43]

Answer:

The Total amount of of 33 boxes of chocolates including taxes is $838.358

Step-by-step explanation:

Given as :

The sales tax rate for city = 4.306%

The sales tax rate for the state = 44%

Total number of boxes = 33

The price of each chocolates = $17.13

So , The price of 33 boxes of chocolates = $17.13 × 33

I.e The price of 33 boxes of chocolates = $565.29

Now total tax including state and city =  4.306% + 44% = 48.306 %

So, The tax amount paid for 33 boxes of chocolates = 48.306 % of $565.29

∴    The tax amount paid for 33 boxes of chocolates = 48.306 % × $565.29

                                                                       = 0.48306× $565.29

                                                                       = $273.068

∴ The Total amount of of 33 boxes of chocolates including taxes = $565.29 +  $273.068 = $838.358

Hence The Total amount of of 33 boxes of chocolates including taxes is $838.358 . Answer
