There is a 173 increase in the student population per year after the college was opened.
16.4 ÷ 10 = 1.64
The easiest way to divide decimals by 10 is to move the decimal point by one place to the left. It's the same if you divide by 100, but in that case you move it by two places. It's also similar with 1000, 10000 etc...
It also applies to multiplying, but in such situation you move the decimal point to the right.
Answer:
A_16x20=320
Step-by-step explanation:
Esto se puede hacer fácilmente de 2 formas.
1) 20 se puede dividir en un múltiplo de 10 y luego multiplicar
16 x 20 =16 x 10 x 2 = 160 x 2 = 320
2) Uso de cero.
Cualquier cosa multiplicada por cero da un cero y luego multiplicar el otro número da el resultado.
16 x 20 = (16 x 2) * 10 = (32) 10 = 320
Así que separamos el cero añadiéndole un 1, lo que lo convierte en 10 y obtenemos el mismo resultado.
This can be easily done in 2 ways .
1) 20 can be broken into a multiple of 10 and then multiplied
16 x 20 =16 x10 x 2=160x 2= 320
2) Use of zero.
Anything multiplied with zero gives a zero and then multiplying the other number gives the result.
16 x 20 = (16x 2) *10= (32)10= 320
So we separated the zero by adding a 1 to it thus making it 10 and we get the same result.
I'll use the same notation as the other one:
3(y-6)<4(y+5)
I'm going to clean this up a bit by distributing:
3y-18<4y+20
Now, subtract 3y from both sides:
-18And now, subtract 20:
-38So y is greater than or equal to -38
Hope this helps!
Answer:
12,000 units
Step-by-step explanation:
Let's first set the equations straight:
C(x) = 15*x + 24000
R(x) = 17*x
Now to break even, the revenue must be equal to the cost:
C(x) =R(x)
15*x + 24000 = 17*x
24000 = 17*x - 15*x
24000 = 2*x
24000/2 = x
12,000 = x
