Answer:
6.125 minutes per song
Step-by-step explanation:
Unit rates are based on a single unit of something. Like price per 1 gallon of gas; price for 1 pound of bananas; miles driven per 1 gallon of gas, etc. What we are looking for in minutes per song.
Use a proportion to solve this with minutes on top and number of songs on the bottom. We know that 49 minutes = 8 songs, and we want to know how many minutes (x) per 1 song:
Cross multiply to get
8x = 49 so
x = 6.125 minutes per song
Answer:
x = 19
Step-by-step explanation:
the question tells you that the angle CBD is 90°.
so, that means that angle DBE and angle CBE add up to 90.
using this, you can make the following equation:
2x - 1 + 5x - 42 = 90
2x + 5x + -43 = 90
7x - 43 = 90
add 43 to both sides
7x = 90 + 43
7x = 133
x = 133/7
x = 19
33 is a decimal
1/3 is a fraction
33% is a percentage
<span>So we wan't to know how much would 14 bags of seeds cost if three bags cost 14.16$. What we wan't first is the price of only one bag of bird seeds and lets call it x. To get that we need to divide the cost of three bags of seeds by 3 and we get that x=14.16$/3=4.72$. So now that we know how much one bag of seeds costs we can simply multiply it by 14 and get our answer: 14*4.72$=66.08$</span>
