3
Step-by-step explanation:
6x - 2w + 9 - 8 = 6x - 2w +1
= 6*2 - 2*5 + 1
= 12 - 10 +1
= 2 + 1 =3
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.
