Answer:
Number of heavy equipment operators hired were 22
Number of general laborers hired were 11
Explanation:
Assume that number of heavy equipment operators hired is x and that number of general laborers is y.
We are given that:
1- Total number of hired people is 33. This means that:
x + y = 33
This can be rewritten as:
x = 33 - y ...........> equation I
2- heavy equipment operators are paid $135, general laborers are paid $89 and that the total payment was $3949. This means that:
135x + 89y = 3949 ............> equation II
Substitute with equation I in equation II and solve for y as follows:
135x + 89y = 3949
135(33-y) + 89y = 3949
4455 - 135y + 89y = 3949
506 = 46y
y = 506 / 46
y = 11
Substitute with y in equation I to get the value of x as follows:
x = 33 - y
x = 33 - 11
x = 22
Hope this helps :)
Queremos encontrar la medida de un lado de un rectangulo, dado que conocemos la longitud del otro lado y el area del rectangulo.
Veremos que el otro lado del rectangulo mide 3/5 cm
Sabemos que para un rectangulo de largo L y ancho W, el area esta dada por:
A = L*W
En este caso sabemos que el area es igual a (15/40) cm^2.
Y sabemos que uno de sus lados (digamos que es el ancho) mide (5/8) cm.
Entonces podemos reemplazar eso en la ecuación del area:
(15/40) cm^2 = L*(5/8) cm.
Ahora podemos resolver esto para L.
L = (15/40 cm^2)/(5/8 cm) = (15/40 cm^2)*(8/5 cm^-1)
L = 3/5 cm
El otro lado del rectangulo mide 3/5 cm
