What role do unit rates have in our daily lives?

Unit rates can be used to help compare deals when it comes to shopping. For example, let's say we have two deals

Deal A: Buy 4 apples for $12

Deal B: Buy 5 apples for $14

Which is the better deal? Which deal offers the lower price per apple? To find out, we divide each dollar amount by its corresponding number of apples

Unit rate for deal A: 12/4 = 3 dollars per apple

Unit rate for deal B: 14/5 = 2.80 dollars per apple

So even though deal B costs more overall, we have a cheaper cost per apple making it a better deal

Unit rates can also apply to speed as well. If person A paints 10 objects in 2 hours, then they paint at a speed of 10/2 = 5 objects per hour. In other words, if one hour goes by, then they painted one whole object. We can compare this to another worker person B. If they paint 12 objects in 3 hours then 12/3 = 4 is the number of objects they paint per hour. We see that person A is the faster painter per hour.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
