The total units of stationery he has would be 55 approximately.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
David keeps a range of stationery in his study.
Let the pencil is represented by x.
Let the erasers be represented by y.
Let the pens be represented by z.
Let n be the stationery.
5/7 of his stationery consists of pencils.
x = 5/7 n
1/6 of the remaining stationery consists of erasers.
y = 1/6 n
There are 20 pens in his study.
z = 20
The total stationery
X + y + z
5/7 n + 1/6 n + 20 = n
20 = n -23/ 36 n
20 = 13 / 36 n
n = 55.38
Therefore, the total units of stationery he has would be 55 approximately.

Answer: it is linear
Step-by-step explanation: A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1
Answer: 72
Go to the very bottom of the table, look at the stem of 7 and the leaf of 2 (largest leaf of the group). Combining the stem and leaf leads to 70+2 = 72
Answer:
a) Ratio of snickers to cookies = 6 : 5
b) Ratio of cookies to snickers = 5 : 6
c) Ratio of cookies to total = 5 : 11
Explanations:
Number of snicker bars = 6
Number of cookies = 5
Total = 6 + 5 = 11
a) Ratio of snickers to cookies = 6 : 5
b) Ratio of cookies to snickers = 5 : 6
c) Ratio of cookies to total = 5 : 11
