A = L * W
A / L = W <==
when A = 42 and W = 16.8
A / L = W
42/16.8 = W
2.5 = W <=== width = 2.5 inches
1.a) 5
b)8
2.a) 30, 60, 90
b) 56, 112, 168
Answer:
5x - 58
Step-by-step explanation:
The 2X and negative 2X cancel out. Then you add the 3 to the -9 to get -6 they you add the lonely Y to the 5Y so now you have 6Y=-6. Then you divide them both by 6 to get the Y alone. 6Y = 6
— —
6 6
So then it’s Y=1. There you go. Hope I helped!!!
I think it will be because if you multiply 1/2 times 4/5 it will be 0.4
