Use a factor<span> tree to express </span>60<span> as a </span>product<span> of prime </span>factors<span>. So the prime factorization of </span>60<span> is 2 × 2 × 3 × 5, which can be written as 2 </span>2<span> × 3 × 5.</span>
Bob's car rental company makes you pay 10 dollars per day you rent the car and a 30 dollar insurance fee
joe's car rental company makes you pay 30 dollars per day you rent the car and a 10 dollar insurance fee
how many days do you need to rent a car for the cost for renting both are the same
bob=10x+30
joe=30x+10
set each to each other
10x+30=30x+10
subtract 10x
30=20x+10
subtract 10
20=20x
divide both sides by 20
1=x
you need to rent 1 day for them to be equal
Each liter of water weighs 1 kg, so the weight of the water in a cubic meter is 1,000 kg.
Solve the equation:
– 3b – (– 2) = 4b <span>– 12
</span>– 3b + 2 = 4b – 12
– 3b = 4b – 12 – 2
– 3b = 4b – 14
– 3b – 4b = – 14
– 7b = – 14
– 14
b = ———
– 7
b = 2 <——— solution.
I hope this helps. =)
