You and three friends go to a restaurant for dinner. you share three appetizers that cost $8 each. you also share two desserts that cost $4 each. you split the total bill evenly. write an expression to find the amount each person paid. then find out how much each person paid. find the error: 3x8+2x4/4 (divided by 4) = 24 + 8/4 =24 + 2 =26 each person pays $26 need an answer !

Each person pays $8

Step-by-step explanation:

The entire sum must be divided by 4.

"three appetizers that cost $8 each": 3 * 8

"two desserts that cost $4 each": 2 * 4

The total cost is 3 * 8 + 2 * 4

Now you must divide the entire sum by 4, so if you write it in a single line, you must use parentheses.

(3 * 8 + 2 * 4)/4 =

= (24 + 8)/4

= 32/4

= 8

Using fractions, it looks like this:

The important lesson from this is that a fraction line is a division but it also means that the numerator must be calculated first, then the denominator must be calculated too, then you divide. When you do not write it as a fraction, but instead, you write in a single line, you must use parentheses where appropriate.

it's both, now can you answer my most recent question?

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
