Agardener is planting two types of trees: type a is 10 feet tall and grows at a rate of 10 inches per year. type b is 6 feet tall and grows at a rate of 16 inches per year. algebraically determine exactly how many years it will take for these trees to be the same height.

8

Step-by-step explanation:

Firstly, we want to convert all values to inches, (1 ft = 12 inches)

So,

Type A is 120 inches tall and Type B is 72 inches tall.

Now,

Type A grows at 10 inches per year and Type B grows at 16 inches per year.

Let x be the number of years passed,

so the height of Type A plants will be after x years have passed.

Similarly, Type B plants will be after x years.

Now, we can equate the two equations to find x.

Therefore, the number of years it will take for these trees to be the same height is 8.

the 3rd option is right

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
