There is no ones place after the decimal so 3 is in the tenth place, so 2.4
So find the prime factors of 52 and order them in order of smalest to biggest
52/2=26
26/2=13
factored form of 52=2 times 2 times 13
order
2,2,13
13 is biggest
answer is 13
To solve this problem we can set up a proportion.
Then cross multiply and divide.
99*6=594/78= 7.6.
Lisa would have had to study about 7.6 hours to get a score of 99.
A dozen of doughnuts cost $5 and a dozen of croissants cost $6.
Step-by-step explanation:
Let,
Cost of 1 dozen doughnuts = x
Cost of 1 dozen croissants = y
According to given statement;
7x+3y = 53 Eqn 1
x+5y = 35 Eqn 2
Multiplying Eqn 2 by 7
Subtracting Eqn 1 from Eqn 3
Dividing both sides by 32
Putting y=6 in Eqn 2
A dozen of doughnuts cost $5 and a dozen of croissants cost $6.
