There are 37 ants, 39 worms, 12 moths, and 11 beetles living in a big garden. Find the sum. Explain your work.
Bas_tet [7]

Answer: 99 insects altogether.

Step-by-step explanation:

Adding two numbers add a time is easiest, rather than adding all four numbers together.

First, add 37 + 39 =. 76

add 12 to that sum, which equals 88.

76+12=88

to that sum, add the final number, 11.

88+11=99

so there are 99 bugs altogether.

A woman is considering two companies from which to rent a truck. triangle truck rental charges ​$20 per day and 35 cents a mile.
Nikitich [7]

You can solve this question using two different methods. One is obviously a hit and trial method in which you keep guessing a number which gives the same amount of total cost. Second is forming two different equations and then solving them using simultaneous methods learnt.

The correct answer is 75 miles. I used the hit and trial method. You can see 20 + 75 * 0.35 = 46.25 and similarly 35 + 75 * 0.15 = 46.25. Hence the same cost.

Cedric and doug each had an equal amount of money. After cedric spent $35 and doug spent $28, the ratio of cedrics money to doug
uysha [10]

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 = x-35

Doug Money left = x-28

the ratio of Cedric money to Doug money was 2:3

Hence the expression can be made as;

\frac{x-35}{x-28}=\frac{2}{3}

Now by cross multiplication method we get;

3(x-35)=2(x-28)

Now we will use distributive property to elaborate the same;

3x-105=2x-56

Combining common terms we get;

3x-2x=105-56

Using Subtraction property we get;

x= 49

Hence $49 they each had at first.
