Ted is five times as old as Roise was when Ted was Roise's age.When Rosie reaches Ted's current age,the sum of their ages will be 72 . Find Ted's current age.​

Answers

Answer: 60

Lets make the people into variables first

Ted = x

Rosie = y

The sum of their ages is 72 so

x + y = 72

Ted is 5 times as old as rosie was when ted was Rosie's age

x = 5y

Now lets put in 5y instead of x so we can solve for y

5y + y = 72

6y = 72

y = 12

If y = 12 then we can put that in to get ted's age

x = 5(12)

x = 60

Ted is 60!

Lets check our work,

since we know the sum is 72 we can add their ages to check,

60 + 12 = 72

Yep! This is right.

Hope this helped! If you could mark branliest i'd appreciate it a lot. Let me know if you need anything else!

Tom needs to plow 1.1 acres of land. If he can plow 5.5 acres in an hour, how many hours will it take?
Help! (16 pts if you answer!)

Answers

Given:

Tom needs to plow 1.1 acres of land.

He can plow 5.5 acres in an hour.

To find:

The time taken by Tom to plow 1.1 acres of land.

Solution:

We have,

Time take by Tom to plow 5.5 acres = 1 hour

Time take by Tom to plow 1 acre = [tex]\dfrac{1}{5.5}[/tex] hour

Time take by Tom to plow 1.1 acres = [tex]\dfrac{1.1}{5.5}[/tex] hour

                                                           = [tex]0.2[/tex] hour

Therefore, the time taken by Tom to plow 1.1 acres of land is 0.2 hour.

How do you find the value of x in the triangle?

Answers

To find the value of x in a triangle, you need to subtract the sum of the two angles from 180 degrees. Know that the sum of all the angles of a triangle will always equals 180 degrees. Then write down the difference of subtracting the sum of the two angles from 180 degrees and that would equal the value of x.

Answer:

Negative

Step-by-step explanation:

On the line, we see that a = 0.5 and b is after -1. a + b will be negative because anything after -1 added to .5 will be negative.

Example:

-1 + .5 = -.5

-2 + .5 = -1.5

-3 + .5 = -2.5

Answer: Negative

Step-by-step explanation: the b we can see is far away from  -1 that means its around - 2 and if we were to add 0.5 and - 2 we would get -1.5
