The number of standard version download and high-quality download is 870 and 490 respectively.
<h3>Number of downloads of the high-quality version</h3>
let
- Number of high-quality download = y
- Number of standard version = x
x + y = 1360
2.9x + 4.1y = 4532
From (1)
x = 1360 - y
Substitute x = 1360 - y into (2)
2.9x + 4.1y = 4532
2.9(1360 - y) + 4.1y = 4532
3944 - 2.9y + 4.1y = 4532
- 2.9y + 4.1y = 4532 - 3944
1.2y = 588
y = 588/1.2
y = 490
Substitute y = 490 into (1)
x + y = 1360
x + 490 = 1360
x = 1360 - 490
x = 870
So therefore, number of standard version download and high-quality download is 870 and 490 respectively.

It's true......................................
We need to look at factors of 2, which are only 2 and 1... How do we get them to add to -3? Well, they have to be negative.
-2 + -1 = -3
What about the multiplication? A negative × a negative = a positive, so
-2 × -1 = 2
So your answer is
-2 and -1
Answer:
(10, 7) or x = 10 and y = 7

Hello Madoudou!
#1
So we have:
F which is the number of faces we are looking for
E which are the numbers of edges
and V the number of vertices
We can use the Euler's polyhedron formula. Which is:
V - E + F = 2
Remember we are solving for F. Thus,
F = E - V + 2
F = 9 - 6 + 2
F = 9 - 4
F = 5
The correct answer is option B
#2
It is almost the same problem. They just want us to find the vertices.
V = E - F + 2
V = 36 - 25 + 2
V = 36 - 23
V = 13
The correct answer is option C
#3
