What multiplies to -29 and adds to 1
Margarita [4]
First set up equation
x times y=xy

so
xy=-29
and
x+y=1
subtract x from both sides
y=1-x
subsitute 1-x for y in first equation
x(1-x)=-29
distribute
x-x^2=-29
add x^2 to both sides
x=-29+x^2
subtract x from both sides
0=x^2-x-29
so we can use the quadratic formula to solve for x if the equation=0 and it is in ax^2+bx+c form so

if
ax+bx+c=0 then x=\frac{ -b+/-\sqrt{b^2-4ac} }{2a} that means x=\frac{ -b-\sqrt{b^2-4ac} }{2a} or x=\frac{ -b-\sqrt{b^2-4ac} }{2a} so


x^2-x-29
a=1
b=-1
c=-29
\frac{ -(-1)-\sqrt{-1^2-4(1)(-29)} }{2(1)}=\frac{ +1-\sqrt{1^2-(-116)} }{2(1)}=\frac{ +1-\sqrt{1^2+116} }{2}=\frac{ +1-\sqrt{117} }{2}= \frac{1-10.816653826392}{2} = [tex] \frac{-9.816653826392}{2}= -4.908326913196



the second number is
\frac{ -(-1)+\sqrt{-1^2-4(1)(-29)} }{2(1)}=\frac{ +1+\sqrt{1^2+(-116)} }{2(1)}= \frac{1+10.816653826392}{2} = \frac{ +1+\sqrt{117} }{2}=  \frac{10.816653826392}{2}=5.908326913196


the two numbers are
5.908326913196 and
-4.908326913196

unos amigos compraron 1/2 de pizza hawaiana 2/4 de peperoni 1/2 de pollo y 3/4 de salchicha ¿cuanta pizza compraron en total?​
sveticcg [70]

Answer:

Los amigos compraron 2 pizzas más \frac{1}{4}

Step-by-step explanation:

Para conocer la cantidad de pizza que los amigos compraron en total, debes sumar la cantidad de cada clase que compraron:

\frac{1}{2} +\frac{2}{4} +\frac{1}{2} +\frac{3}{4}

Para sumar estos valores, debes encontrar un denominador común. Como 4 es múltiplo de 2, el 4 puede ser usado como denominador común. Este común denominador se divide entre el denominador de cada fracción. El resultado de la división se multiplica por el numerador de la misma fracción. Una vez que se divide y se multiplica, el resultado se coloca en el numerador. Realizando el mismo procedimiento con cada fracción y se realiza la suma con los numeradores que resultaron:

\frac{1}{2} +\frac{2}{4} +\frac{1}{2} +\frac{3}{4}=\frac{2+2+2+3}{4} =\frac{9}{4}

Siendo \frac{9}{4} =2.25=2\frac{1}{4}, entonces <u><em>los amigos compraron 2 pizzas más </em></u>\frac{1}{4}<u><em></em></u>
