Answer:

520 - 303.93 - (10.99 * 4) - 25.25 - 73.43x ≥ 0

-

1) Parentheses

520 - 303.93 - 43.96 - 25.25 - 73.43x ≥ 0

-

2) Combine like terms

146.86 - 73.43x ≥ 0

-

3) Get the variable term alone

-73.43x ≥ -146.86

-

4) Divide to solve

x ≤ 2

** dividing by a negative number, the inequality sign flips **

ANSWER :

x ≤ 2

Step-by-step explanation:

303.93+(4×10.99 )+25.25+73.43x = 520

303.93 + 43.96 + 25.25 + 73.43x = 520

373.14 + 73.43x = 520

73.43x = 520 - 373.14

73.43x = 146.76

x = 146.76 ÷ 73.43

x = 2

x ≤ 2

un rectangulo tiene 28 cm de perimetro y unos de sus lados mide 4 cm ¿cuantos cuadrados de 2 cm por lado se mecesitan para armar
seraphim [82]

Answer:

10 cuadrados

Step-by-step explanation:

Si uno de los lados de rectangulo es de 4cm entonces el lado parallelo tambien es de 4cm. Eso nos da 8cm del perimetro y nos quedan los otros dos lados que tienen la misma medida. Entonces dividimos el resto del perimetro por 2.

28 - 8 = 20cm

20cm / 2cm = 10cm

Ahora que tenemos todas las medidas podemos multiplicar el largo por el ancho para calcular el area del rectangulo

10cm * 4cm = 40cm^{2}

el cuadrado de 2cm tendra un area de

2cm * 2cm = 4cm^{2}

Ahora simplemente dividimos el area del rectangulo por el area del cuadrado para saber cuantos cuadrados necesitamos para armar ese rectangulo

40cm^{2} / 4cm^{2} = 10 cuadrados

Given Triangle DEF is isosceles and angle D is the vertex angle, Find x, DE, DF, EF
ch4aika [34]

Answer:

x=2;DE,EF=9,DF=5

Step-by-step explanation:

Since DEF is isoceles, you can set the equations

x+7 and 2x+5 equal to each other

x+7=2x+5, now solve for x

-x=-2,

x=2, now plug in for each side

DE,EF=9

DF=3(2)-1=5
