So it would be 4x+108= 180 because it’s a straight line so x=18. For the second one id say A and D
Answer:
6x-5/2
Step-by-step explanation:
4x+1/2+2x+(-3)
4x+2x+1/2-3
6x+1/2-3
6x+1/2-6/2
6x-5/2
We know that
<span>A large pump can drain an 80,000 gallon pool------------> in 3 hours
X gallons---------------------------------------------------------> in 2 hour
X=2*80000/3----------> 53333.33 gallons in 2 hour
therefore
</span><span>the smaller pump in two hours drain an [80000-53333.33]=26666.67 gallons
</span><span>
if the </span>smaller pump drain 26666.67 gallons-----------------> in 2 hours
<span> 80000 gallons------------------------------------------------> X
X=80000*2/26666.67------> 6 hours
the answer is
</span><span>the smaller pump to drain the pool by itself would take 6 hours</span><span>
</span><span>
</span>
