Answer:
B
Step-by-step explanation:
Answer: 4000 Grams
(Edited! I was wrong!)
Step-by-step explanation:
32 divided by 8 is 4. Add the units, and youre done! (x1000 bc 1000 kg are in a gram)
Given: A= 52ft² and l= 2w-5
know that formula for A= lw, substitute for what you know and solve for w
52=(2w-5)w -> w= -4, w=6.5 but because a width measurement can not be negative, you can eliminate w=-4. so the width is equal to 6.5ft
now input that in the equation for length and solve for l:
l=2w-5=2(6.5)-5=8
so the length is 8 ft
Answer: 15 gallons are needed
Step-by-step explanation: Simplify the ratio 5:2, which is 2.5:1. Multiply 6 on both sides to get 15:6. :)
