Answer:
there are 4 weeks in a month so if 45 kg is for 1 week then
Step-by-step explanation:
x=4 (weeks in a month)
=45x
=180 kg of rice
1/(3b)=4/5 multiply both sides by 5
5/(3b)=4 multiply both sides by 3b
5=12b divide both sides by 12
b=5/12 (not sure why you don't have that as an option in your answers, perhaps I misunderstood your description of the original equation...)
Answer:
c is the correct answer
Step-by-step explanation:
because i worked it out
B. (9,126)
<span>y + 18 = 16x
=>y=16x-18
0.5x + 0.25y = 36 (multiply both sides by 4)
=>2x+y = 144
Substitute y=16x-8
=>2x+16x-8=144
=>18x=152
=>x=152/18=9
y=16x-18
=>y=16(9)-18
=>y=144-18=126
Answer: x=9 and y=126</span>
B Is the answer ......... z
