Answer:

y = 30

Step-by-step explanation:

We can use ratio's to solve this

40        20

-----  = -----------

100       20 + y


Using cross products

40 * (20+y) = 20*100

Distribute

800 + 40y = 2000

Subtract 800 from each side

40y = 2000-800

40y = 1200

Divide by 40

y = 1200/40

y =30

<h3>What is an inequality?</h3>

An inequality can be defined as a relation which makes an unequal comparison between two numbers or mathematical expressions.

It is used most often to compare two numbers on the number line by their size

The information given be represented as;

8 - 37\geq 29

Now, let's find the difference from the left side

We have;

- 29\geq 29

From this, we can see that the statement is wrong as - 29 is neither greater than or equal to 29

The correct statement should be; 8 -  27 is less than 29

Thus, the statement that 8-37 greater than or equal to 29 is false and the correct statement is 8 -  27 is less than 29
