X=7/3
solution steps:
subtract 2 from both sides
subtract 2x from both sides
Answer:
y = 7/2 -2
Step-by-step explanation:
if the slope of the first problem is -2/7 then its perpendicular is 7/2 (the exact opposite) and since the y- intercept is the b in Y= mx +b the intercept of the equation you’re trying to find is -2
143 is composite. To be prime it has to have only 2 divisors i.e it's self and one but since it has 4 divisors ( 143, 1, 11 and 13) it is composite.
De ahí que la fracción de la mantequilla total que corresponde a cada postre sea 1/4
Si con 16 barras de mantequilla se prepararon 20 postres, esto se puede expresar como:
16 pegatinas = 20 postres
Para obtener la fracción del total de mantequilla que corresponde a cada postre, podemos escribir;
x = 1 postre
Divide ambas expresiones
16 / x = 20/1
20 veces = 16 * 1
20x = 16
x = 16/20
x = 4/5
De ahí que la fracción de la mantequilla total que corresponde a cada postre sea 1/4
