Dinner cost $45.50 you left 20% how much did you spend

I found a place that will give me 20% discount if I spend over $50.My bill $75.How much money will I save? What is my final bill

kenny6666 [7]

Answer:

You will save: $15

Total cost: $60

Step-by-step explanation:

First turn the percent into a decimal.

To do so move the . over to the left twice.

20% - .20

Now multiply 75 by .20

75 x .20 = 15

So you will save $15

Now subtract 15 from 75

75 - 15 = 60

Consider this system of linear equations: y=4/5x-3 y=4/5×+1 a. Without graphing, determine how many solutions you would expect t

pychu [463]

The solution of a system of linear equations is the point where the two lines meet. Note that for the given equations, both lines have the same slope (4/5). If two lines have the same slope, it means that those lines are parallel. Parallel lines do not meet at any point, they stay parallel to the infinite.

Therefore, since this two lines are parallel, they don't meet and the system has no solution.

Explain real numbers, rational numbers, and irrational numbers please.

Lady_Fox [76]

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers.

All numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction.An irrational number has endless non-repeating digits to the right of the decimal point. Although irrational numbers are not often used in daily life, they do exist on the number line. In fact, between 0 and 1 on the number line, there are an infinite number of irrational numbers!
