Na fazenda Santa Elisa onde a principal atividade a criação de gado cada hectare deve ser ocupado por 20 bois quantos bois podem ser criados no terreno de 70000 m²

140 bois

Step-by-step explanation:

Observe que:

1 hectare = 10000m²

Na Fazenda Santa Elisa, principal atividade da pecuária, cada hectare deve ser ocupado por 20 bois

Isso significa:

10000m² = 20 bois

O número de bois que podem ser criados no local de 70000 m² é calculado como:

10000m² = 20 bois

70000m² = x

Multiplicação cruzada

10000m² × x = 70000m² × 20 bois

x = 70000m² × 20 bois / 10000m²

x = 140 bois

Portanto, 140 bois podem ser criados em um terreno com 70000m².

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
