Its asking for the units being used so the answer is Inches
(1) 20:4=5:1. 80:16 16 weeks since he’s doing 5per week, and 80 divided by 5 is 16.
(2) 6:3=2:1. 10:5 It will take 5 hours because she’s walking 2km per hour, so it would take 5 hours to walk 10km.
(3) 1:20 4:80 It will take 80 minutes because 20x4=80
(4) 1:1 20:20 it will take her 20 days since she makes one craft a day and she’s making 20.
(5) 12:1 84:7 84 cakes since there is 7 days in a week. 12x7=84
If you still need help, here’s the answers
Slope = 2/3
y = mx + b
6 = 2/3(3) + b so b = 4
equation
y = 2/3x + 4
3y = 2x + 12
answer is c.3y = 2x + 12
-3.132 is the answer, you just had to multiply all of them one at a time (:
