You check 20 batteries. Fourteen batteries do not have a charge. Out of the next 70 batteries that you check, how many would you expect to not have charge?

                                                           Solution:

Check batteries=20

Battreies do not have charge=14

Out of the next batteries that you check=70

Expect to not have charge=30

Answer is 30.

Step-by-step explanation:

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
