Answer:
The toy replica is smaller than the model in the lobby
Step-by-step explanation:
Model in the lobby: 1:103
Toy Replica: 1:200
1:200 < 1:103
1:200 = 1/200
1:300 = 1/300
122
286-42=144
144\2=122
122(peter)+164(malco)=286(total weight)
A-2: Project D.
b: Project A.
Not sure about a-1, hope I helped.
2/3x - 1/2y = 3 |multiply both sides by 6
4x - 3y = 18
1/2x + y = 5 |multiply both sides by 2
x + 2y = 10
Answer: B) 4x - 3y = 18 and x + 2y = 10
