He should buy 5 blue ones and 6 green ones, in total 11! Hoped I helped u!
Answer: 2,3,8
Step-by-step explanation:
if,
x+y+z=13
2x+5y+6z=67
5x-y=7
Solve [x+y+z=13 2x+5y+6z=67] to find: -3x+z=2 and keep
|
x+y+z=13
5x-y=7
6x+z=20 and -3x+z=2
z=8
x=2
y=3
Well to be honest this question is really easy by what i understand, if you just need any one line to get a total of 21.
Obviously having three or four such lines might become a problem But not for this. You can obviously break down 21 in to three different categories or numbers like 1 7 and 13. And now put 13 in the middle and start from anywhere. You will get 21 along one such line.

The value of the modulus function |-3| is 3.
<h3>What is the value of modulus?</h3>
'Modulus' exists a Latin word, which signifies 'measure'. Absolute value is commonly referred to as numeric value or magnitude. The absolute value designates only the numeric value and does not contain the sign of the numeric value. The modulus of any vector quantity exists ever taken as positive and exists in its absolute value.
The absolute value (or modulus) | x | of a real number x stands as the non-negative value of x without regard to its sign.
For example, the absolute value of 5 stands at 5, and the absolute value of −5 exists also at 5. The absolute value of a number may be considered as its distance from zero along a real number line.
Therefore, the value of the modulus function |-3| is 3.
