calculate a unit rate for the following:
emily bakes 4 cakes in 5 hours
0.8 cakes were made per hour
3x<15
x<5
5x - 2 < 8
x < 2
graph x<-2
simplify the ratio:
100:45
20:9

b. 400 meters
c. 1 cake baked in 2 hours
d. 7 kids in 1 group
A and D
20x>-10
x>-1/2
7<4-2y
y<-3/2
graph x is greater than or equal to -8
closed circle, line to right
write an equivalent rate by scaling up
2:3
4:6, 6:9, 8:12, etc
calculate a unit rate for the following:
patricia ran a 400 meter race in 60 seconds
6.67 meters per second
-1/3x<12
x>-36
-3z+4<15
z>-11/3
graph 2 is greater than or equal to x
closed circle, to the left
what is the scale/multiplier between these two ratios?5:9 and 15:27
multiply by 3
which is a better deal?
$2.79 for a pack of 12 colored pencils or $3.59 for a pack of 20 colored pencils
$0.23 per pencil in the 12 pack
$0.18 per pencil in the 20 pack
20 pack is a better deal
-2x<1/4
x>-1/8
88 < 37 + 3x
x>17
solve and graph the solution
17<2-3x
open circle at 15, line to the left
3:7=?:42
3:7=18:42
which is a better rate?
$2.39 for a single pack of oreos or $5 for a buy 2 get one free deal
$5 for a buy 2 get one free, because it comes out to $1.67 per pack of oreos
