Evaluate 20.003+[(30.1+5.75)-6.87
Amanda [17]

Answer:

48.983.

Step-by-step explanation:

(The parentheses are not balanced so I am assuming that there is a square parentheses at the end of the given expression).

Using order of operations (PEMDAS):

20.003 + [(30.1 + 5.75) - 6.87]     Work out the inner parentheses first:

= 20.003 + [35.85 - 6.87]             Now the outer parentheses:

= 20.003 + 28.98

= 48.983.

Given :

New York City has a population of 8.55 million and 300 square mile area .

Manhattan has 1.64 million and 23 square miles area .

To Find :

How much greater is the population density of Manhattan than New York City.

Solution :

Population density of New York City :

D_{NY}=\dfrac{8.55}{300}=0.029 \ million/mile^2\\\\D_{M}=\dfrac{1.64}{23}=0.071 \ million/mile^2

Now ,

D_{M}-D_{NY}\\\\(0.071-0.029)=0.042\ million/miles^2

Therefore , population density of Manhattan is 0.042\ million/miles^2 greater than New York City .

Hence , this is the required solution .

Select the correct first step to solve the follow equation: −4(x−5)=−7x+10
Otrada [13]

Answer:

x = -10/3

Step-by-step explanation:

−4(x−5)=−7x+10

Use the distributive property to multiply −4 by x−5.

−4x+20=−7x+10

Add 7x to both sides.

−4x+20+7x=10

Combine −4x and 7x to get 3x.

3x+20=10

Subtract 20 from 10 to get −10.

3x=−10

Divide both sides by 3.

x = -10/3
