how many solutions does the following equation have?
4(2x+3)-7=8x+5
a- infinite
b- no solution
c- one solution

Answers

A-Infinite. If you distribute the 4 to the 2x+3 you get 8x+12-7=8x+5. This simplifies to 8x+5=8x+5 which means no matter what the value of x is, the two sides of the equation will be equal to each other.

If –3p – 2 (6 – p) > -7, then which statement is true?

Answers

Answer:

-5

Step-by-step explanation:

Given:
p: 20-5=5
q:40-6=14
P 9
Write the contrapositive in if-then form.
If 2 -5=5, then 4x -6=14.
If 4x--6=14, then 2x-5=5.
If 2x -- 5≠5, then 4x--6≠14.
If 4x - 6≠14, then 2x - 5≠5.

Answers

Answer:

We conclude that:

If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.

Step-by-step explanation:

We know that the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p".

In other words, it is symbolically represented as:

' ~q ~p is the contrapositive of p q '

For example, the contrapositive of "If there is a snow outside, then they cancel the event" is "If they do not cancel the event, then it would not be snow outside."

Given

p: 2x -5=5q: 4x-6=14

As the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p

Therefore, we conclude that:

If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.

You want to purchase a new bike that costs $142.68. To save for the bike, you mow your neighbor's yard for $40 each week. How much money will you have left over if you buy the bike after saving for 4 weeks?

Answers

The amount of money left after purchasing the bike is $17.32

How to calculate the amount of money left ?

The cost of the new bike is $142.68

I need to save for the new bike and i decided to mow the neighbour's yard

The money paid is $40, this will be done for 4 weeks

At the end of the four weeks, the money i will get can be calculated as follows

= 40 × 4

= 160

To calculate the money left, let's subtract the cost of the bike from 160

= 160 - 142.68

= 17.32

Hence the amount of money left after buying the bike is $17.32

There are 5280 feet in a mile and 60 minutes in an hour (needless to say). How fast is a car going 30 miles per hour traveling in feet per minute?

(Please help me)

Answers

Answer:

2640 feet in a minute.

Step-by-step explanation:

Since the car is going 30 miles per hour, and there are 5280 feet in one mile, you would multiply 30 by 5280.

30 * 5280 = 158400

So 154800 feet = 30 miles.

Since you want to find out how fast a car going 30 miles per hour is traveling in feet per a minute, you would divide 154800 feet by 60, since there are 60 minutes in an hour.

154800 / 60 = 2640.

So 2640 feet in a minute.

If you want to check this, you can do 2640 * 60, which indeed equals 154800.

Hope this helps.

roblem 1.12: calculate the average volume per molecule for an ideal gas at room temperature and atmospheric pressure. then take the cube root to get an estimate of the average distance between molecules. how does this distance compare to the size of a molecule like { n } { 2 }n 2 or { h } { 2 }oh 2 o?

Answers

An ideal gas follows the ideal gas law stating PV = nRT. Obtain the average volume/mole by solving for V/n. Divide both sides by Avogadro’s constant Na. Multiplying n and Na gives the number of molecules N. V/N is the average volume/molecule. 250C is the room temperature = 298.15K. The atmospheric pressure is 101325 Pa or 1 atm. Each molecule in a gas is spaced evenly and placed in a lattice. To obtain the space taken up by a cube, find the cube root of V/N to obtain the average intermolecular distance. For small molecules such as N2 or H2, the angstroms order is 10^(-10) m. The intermolecular distance is about 10 times the small molecules.

P V = nRT

V⁄n=RT⁄P

V⁄(nNa )=RT⁄(PNa )

V⁄N=((8.314 J/(mol.K))(298.15K))/((101325Pa)(6.02×10^23 molecules/mol))≈4.06×10^23 m^3/molecule

∛(V/N)≈3.44×10^(-9) m = 3.44 nm

The intermolecular distance is about 10 times the small molecules.

If using the method of completing the square to solve the quadratic equation

square"?

The number to add is (11/2)^2 = 121/4

Step-by-step explanation:

Here, we want to know the number that will complete the square

We rewrite the equation as follows;

x^2 + 11x = -30

x^2 + 11x + (11/2)^2 = -30 + (11/2)^2

x^2 + 11x + 121/4 = -30 + 121/4

C: 42x - 8y - 5.3
D: 84x - 16y - 5.3

Answers

Answer:the answer is a

Step-by-step explanation:

The expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

= 2(14x - 3y + 28x + 12.2 - 5y - 17.5)

= 28x - 6y + 56x + 24.4 - 10y - 35

Adding like terms

= 84x - 16y -10.6

Thus, the expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.
