X=120
2/5-(x/300)=0
Simplify= X/300
2/5-X/300=0
Simplify=2/5
2/5-X/300=0
The left denominater is: 5
The right denominater is: 300
P = 2(L + W)
P = 84
L = 35
now we sub
84 = 2(35 + W)
84 = 70 + 2W
84 - 70 = 2W
14 = 2W
14/2 = W
7 = W....so the width is 7 cm
Usando proporciones, hay que el error maximo que se puede cometer al medir el diametro de un circulo, en cm, es de
.
<h3>¿Qué es una proporción?</h3>
Una proporción es una fracción de la cantidad total.
En este problema:
- La cantidad total es el diametro de un circulo, cuya medida es 10 cm.
- El erro maximo es de 5% de esto, o sea:
![\pm 0.05(10) = 0.5](https://tex.z-dn.net/?f=%5Cpm%200.05%2810%29%20%3D%200.5)

Answer:
18t >= 78
Step-by-step explanation:
Not sure if there's an equals sign in the problem that you were given, but there should be. The 18 in the inequality stands for the hourly wage. The t stands for hours worked. 18(wage) x t(hours) has to be greater than or equal to 78 in order for Martin to at LEAST $78 per day. :)
