6x+8x+40=180
14x = 140
x = 10
7y + 3y - 10 = 180
10y = 190
y = 19
We know,
1 MB = 1000 KB
513 MB = (1,000 * 513) KB
= 513,000 KB
Now,
1 KB = 1,000 bytes
513,000 KB = (1,000 * 513,000) bytes
= 513,000,000 bytes
∴ 513 MB is 513,000,000 bytes
First you would divide by 2 in both sides
P/2 = l + w
Then you would subtract w from both sides
P/2 - w = l
This is the easiest method do isolate l
You can also distribute the 2 to ( l + w) first
P= 2l + 2w
Then subtract 2w from both sides
P - 2w = 2l
Then you would divide by 2
(P - 2w) / 2 = l
P/2 - w = l
Answer:
55
Step-by-step explanation:
3x - 60 = x + 50
3x = x + 50 + 60
3x = x + 110
3x - x = 110
2x = 110
110 / 2 = 55
