Answer:
y = 750 -100x
Step-by-step explanation:
The initial remaining balance is 750. The balance decreases by 100 per month, so is reduced by 100x. The equation describing this is ...
y = 750 -100x
3(6x-8)-(-4x-7)
18x-24+4x+7
ANSWER= 22x-17
Answer:
560 downloads of standard version downloads.
Step-by-step explanation:
Let there were number of standard version of downloads = x
and number of high quality version of downloads = y
There were total 950 downloads of the both type of songs.
x + y = 950 -----(1)
Size of the standard version songs = 2.8 MB
and the size of the high quality version songs = 4.4 MB
Total download size = 3284 MB
2.8x + 4.4y = 3284
7x + 11y = 8210 -----(2)
Multiply equation (1) by 11 (-) equation (2)
(11x + 11y) - (7x + 11y) = 10450 - 8210
4x = 2240
x = 560
There were 560 downloads of the standard version downloads.
The equation can be written as (2x-3)^2
Ans since it is square, then we can take the root of the equation to find on side of the square, which is (2x-3) and by multiplying it by4, we can find the perimeter.
Answer:
486 sq. in
Step-by-step explanation:
Find the area of one face
Area = s^2
s = 9 in
Area = 9^2
Area = 81
Area 6 sides
There are 6 sides to a cube. So if you have the area of 1 side, you need only multiply by 6 to get the area of the cube
Area = 6 * 81
Area = 486
