Answer:
$2.85
Step-by-step explanation:
First, we’re going to find the total the Uncle paid:
8.7 + 10.3 = 19
15% is 0.15 (You divide 15/100)
To find how much the tip was, we multiply 19 and 0.15
19(0.15) = 2.85
The uncle left a $2.85 tip

Step-by-step explanation:
First you multiply 45 and 25, which equals 1,125. Then you add 53 & 27, you get 90. You divide the 1,125 by 90 and get 12.5
Responder:
3 / 4x + 1/2 = x
Explicación paso a paso:
Dado que:
Capacidad total = x
Volumen inicial = cierta fracción * capacidad total
Volumen adicional agregado para llenar = 1/2
Por eso,
Inicial. Volumen + volumen adicional = volumen total
De las opciones:
Un volumen inicial de 3 / 4x
Volumen adicional de 1/2
Volumen total = x
Sumar todo hace que la ecuación:
3 / 4x + 1/2 = x
x - 3 / 4x = 1/2
Por lo tanto, la ecuación correcta de la opción es: 3 / 4x + 1/2 = x
Answer:
x ≈ 11.09
Step-by-step explanation:
Using the rule of logarithms
x = n ⇒ x = 
Given
ln(x + 9) = 3 , that is
(x + 9) = 3 , then
x + 9 = e³ ( subtract 9 from both sides )
x = e³ - 9 ≈ 11.09 ( to the nearest hundredth )
