Step-by-step explanation:
Given
Phone Battery Life (hours)
A 20
B 25
C 10
D 18
8.45% of the battery life of each mobile phone is used in a day by a typical user
Calculating Hours of battery life in a day for each mobile
A 20
Battery life for A =
hours
B 25
Battery life for B =
hours
C 10
Battery life for C =
hours
D 18
Battery life for D =
hours
Therefor Mobile phone A 20 uses a total of 1.69 hours of battery life in a day
First, we write the first equation where the left side contains x and y in the right side. We do as follows:
x = 2y + 6
You, then substitute the equation to the second one.
3(2y + 6) + y = 8
6y + 18 + y = 8
7y = -10
y = -10/7
x = 22/7
10 * $1 = $ 10
$10 / 10 = 1
one 10$ bill
pretty simple
Answer: 14
Step-by-step explanation: 6 + 2(2x-3) = 2x+12 =
This always first in a problem (2x-3) then 6 + 2 then answer (2) for 1st one
Then you do 2x+ 12 which is (14)
