4.30A+5.70B=855.40
A+B=168
A=168-B
substitute
4.30(168-B)+5.70B=855.40
4.30*168-4.30B+5.70B=855.40
1.40B =855-4.30*168
1.40B=132.60
B=132.60/1.40= 94.7 pounds≈95 pouds

Answer: Choice C</h3>
2x-y = 0
=============================================
Work Shown:
x = (1/2)y
2x = y ... multiply both sides by 2
2x-y = 0 ... subtract y from both sides
This is in standard form Ax+By = C, where A,B,C are integers. In this case, A = 2, B = -1, C = 0.
Answer:
The answer is B.
Step-by-step explanation:
Answer:
A =½bh
A=½*15*5⅓
A=½*15*16/3
A=1*15out of 2 time's 16/3
A=15/2*16/3
reduce
A=20 square units
