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:
Step-by-step explanation:
The answer is $27.23 for the commission
Work out problem:
495×5.5%=27.225
So you round that off to 27.23
When working with a problem with percentages, you always multiple to figure out how you got your and what is your answer.
What are u asking me to do, the picture is upside down I think, and I can respond in commenting
To find the answer, we can use the angles sum of triangle, where the sum of angle of a triangle will be 180°.
In this case, we can set an equation to find the answer:
35°+52°+3(x+2) = 180°
3x + 3(2) = 180°-35°-52°
3x = 95 - 6
x = 87/3
x = 29
Therefore, x = 29.
We can then find the measure of angle C by putting the value x in the equaiton:
3((29)+2)
=29(3) + 2(3)
=87 + 6
= 93°
Therefore, angle C is 93°.
Hope It helps!
Answer:
Question 675528: A ball is thrown vertically upward with an initial velocity of 48 feet per second. If the ball started its flight at a height of 8 feet, then its height s at time t can be determined by s(t)=-16t^2+48t+8 where s(t) is measured in feet above the ground and t is the number of seconds of flight.
