Hello!
15 < x + 4
We can subtract 4 from both sides, to cancel it out.
15 - 4 is 11.
11 < x
x = {12,13,14,15,16,..........................................................................Infinity}

Answer:
78 ml of 7% vinegar and 312 ml of 12% vinegar.
Step-by-step explanation:
Let x represent ml of 7% vinegar brand and y represent ml of 12% vinegar brand.
We have been given that chef wants to make 390 milliliters of the dressing. We can represent this information in an equation as:
We are also told that 1st brand 7% vinegar, so amount of vinegar in x ml would be .
The second brand contains 12 vinegar, so amount of vinegar in y ml would be .
We are also told that the chef wants to make 390 milliliters of a dressing that is 11% vinegar. We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, the chef should use 78 ml of the brand that contains 7% vinegar.
Upon substituting in equation (1), we will get:
Therefore, the chef should use 312 ml of the brand that contains 12% vinegar.
In order to subtract 2.34 from 20, the best method is using column subtraction.
To do this, we put the main number on top, and the number we are taking away underneath it.
When we set it out, we need to make sure that all the columns line up properly, the units in one line, tens in the other etc.
If taking decimals from a whole number, I would always recommend putting '0's after the decimal point for place value.
For the layout, see below:
20.00
- 2.34
Now, as we cannot subtract 4 from 0, we must begin borrowing from the neighbours.
As 2 is the nearest number, we take one from there and move it next door
1¹0.00
Do the same again, 10 becomes 9
19.¹00
And one last time
19.9¹0
Now subtract 2.34 from 19.9¹0
19.9¹0
- 2.34
10 - 4 = 6
9 - 3 = 6
9 - 2 = 7
1 - 0 = 1
17.66
