Answer:
Melissa
Step-by-step explanation:
Melissa: 18/20
Tom: 85/100
Find the common denomenater so multiply 18*5 and 20*5
Melissa: 95/100
95>85
Melissa has the greater mark
2+6=8
8 units
6/8=3/4=0.75 per unit
2 times 0.75=1.5
6 times 0.75=4.5
2 parts compost so 1.5kg compost
I can't figure out how to show the actual graph, but top solve the problem, you
take any x or y value (I like to start at 0) and plug the number into the equation.
The graph shifted to the right 6 so we added 6. Therefore k=6
LCD(12, 23, 54) = LCM(2, 3, 4) = 22×3 = 12
12 = 612
23 = 812
54 = 1512
