Curt has 12 models in all. three of the models are airplanes. curt has 5 more model cars than boats . how many models of cars does curt have?

7

Step-by-step explanation:

Given : Total number of models Curt has = 12

Curt has 5 more model cars than boats .

Number of models of car =3

Let x be the number of boats he has , then the number of models of cars he has will be x+5 .  (1 )

According to the question , we have

Subtract 8 from both sides, we get

Divide both sides by 2, we get

Now, the number of models of cars = 2+5=7      [From (1)]

Hence, Curt has 7 models of cars.

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
