Answer:
Each of them had $49 at first.
Step-by-step explanation:
Given:
Cedric and Doug each had an equal amount of money.
Let the number of money they had at first be x
Cedric spent = $35
Doug spent = $28
Cedric Money left =
Doug Money left =
the ratio of Cedric money to Doug money was 2:3
Hence the expression can be made as;
Now by cross multiplication method we get;
Now we will use distributive property to elaborate the same;
Combining common terms we get;
Using Subtraction property we get;
Hence $49 they each had at first.
Answer: a. 126.20 gallons.
b. 2740 miles.
Step-by-step explanation:
We will use unitary method in this question.
a) ∵ 310 miles can be covered by a car with the help of 15.5 gallons of gasoline
∴ 1 mile can be covered = gallons
∴2524 miles can be covered =
= 126.20 gallons
b). ∵ With 15.5 gallons of gasoline car can be driven = 310 miles
∴ With 1 gallon of gasoline car can go = 310/15.5 miles
∴ With 137 gallons can can go = (310×137)/15.5 miles
= 2740 miles.
Answer:
B=7x
Step-by-step explanation:
5(x+2)+2(x-5)
5x+10+2x-10
since 10-10=0, it just won't show, there's no need to say "0"
5x+2x+10-10
7x+0
so just
7x
-3/2 or -1 1/2 is the answer
