Answer: There are 2 students

Explanation: Each adult is equal to 5$ so If you divide 104$ by 5$ and only 20 numbers of 5 can fit in 104, and so your left with the number 4 and since each student it equal to 2 dollars that would mean 4 divided by 2, and the answer to that would be 2.

Hopes this helps mate :)

Can someone solve 5 + 2x = + 6<br><br> and n - 3n = 14 - 4n<br><br> and 7 ( 5a - 4 ) - 1 = 14 - 8a
professor190 [17]

Answer:

5 + 2x = 6

2x = 6-5

2x = 1

x = 0.5

n -3n = 14 -4n

-2n = 14-4n (since 4n is negative, change the sign to make it positive and then add 4n to both sides of the equation)

2n = 14

n = 7

7 (5a - 4) - 1 = 14 - 8a

35a - 28 - 1 = 14 -8a

35a -29 = 14 - 8a

43a = 43

a = 1

PLEASE HELP!!!

How do you calculate it? You start by expressing the density in the units you have. Then you multiply by appropriate conversion factors to get to the units you want. Treat units as though they were any other variable. A value cancels that appears in both the numerator and denominator of a fraction.

\dfrac{56.15\,kg}{0.222\,hh}\cdot \dfrac{1000\,g}{1\,kg}\cdot \dfrac{1\,pw}{1.55\,g}\cdot \dfrac{1\,hh}{238.5\,L}\cdot \dfrac{9.091\,L}{1\,pk}\\\\=\dfrac{56.15\cdot 1000\cdot 9.091\,pw}{0.222\cdot 1.55\cdot 238.5\,pk}\\\\ \approx6220\,\frac{pw}{pk}

shusha [124]

Answer:

16 units

Step-by-step explanation:

You would take the area of the door (which would be 8 times 3) and subtract the area of the poster (which is 4 times 2).

Next, you would set up your equation: 24-8 which is 16.

Hope this helps! :)
