Answer: The answer is 5x+6

Step-by-step explanation:

1/3(9x+16+2)+2x

= 1/3(9x)+1/3(16)+1/3(2)+2x

=3x/1+16/3+2/3+2x/1

=3x/1+2x/1+16/3+2/3

Take the L.C.M

=3x+2x/1+16+2/3

=5x/1+18/3

=5x+6

Ajay reads aloud from a sports magazine. He comes across the measurement 0.63 kilometer. How should he read this measurement alo
Mashutka [201]

Answer:

"sixty-three hundredths of a Kilometer"

Step-by-step explanation:

Decimal measurements are read based on the place of their digits. In this case, Ajay would read this measurement as "sixty-three hundredths of a Kilometer". This is because the final digit of the decimal form measurement is in the "hundredths" position. One more to the right and it would be in the "thousandths" while one more to the left would be the "tenths"

Se requiere dos personas para construir una barda de 20 m de largo y 1.5 m de alto en dos días ¿cuántas personas se necesitan pa
Wewaii [24]

Answer:

Definamos R como la "velocidad" a la que una persona puede construir la barda dada.

Supongamos que la persona necesita un tiempo T para construir la barda, entonces tenemos la relación:

R*T = 1 barda.

Si dos personas trabajan juntas la velocidad de trabajo va a ser (R + R), y sabemos que ellos pueden completar el trabajo en 2 días, entonces:

(R + R)*2 días = 1 barda

(2*R)*2 días = 1 barda

(2*R) = (1/2) barda por día

R = (1/2)*(1/2) barda por día = (1/4) barda por día.

Esto significa que una persona puede completar un cuarto de la barda en un día de trabajo.

Ahora queremos saber cuantas personas se necesitan para construir una barda en solo medio día, entonces debemos resolver:

(N*R)*0.5 días = 1 barda

Donde N es el número de personas que queremos obtener.

(N* (1/4) barda por día)*0.5 días = 1 barda

N*(1/4) barda por día = (1/0.5) bardas por día = 2 bardas por día

N = 2/(1/4) = 2*4 = 8

N = 8

Se necesitan 8 personas para construir una barda en medio día.
