A cell phone company has a basic plan of $40 plus $0.45 for any minutes over 700. Before receiving his statement, John saw he was charged a total of $48.10. Write and solve an equation to determine how many minutes he must have used during the month. Write an equation without decimals.

Step-by-step explanation:

Let

x ----> the number of minutes

y ----> the total charge in dollars

we know that

For x>700 min

so

For y=48.10

substitute

Multiply by 100 both sides

----> equation without decimals

solve for x

To find out the total minutes we need to sum

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
