2x + 5 /3x + 7 = 3/5 find X plz​

Mathematics
1 answer:
noname [10]3 years ago
6 0

Answer:

x = -96/55

Step-by-step explanation:

Given that 2x + (5 /3)x + 7 = 3/5

Firstly, we have to multiply through out the expression by the common denominator. We can see that the denominators are 3 and 5, hence the common denominator is 15. Multiplying through by 15 gives:

2x * 15 + (5 /3)x * 15 + 7 * 15 = (3/5) * 15

30x + 25x + 105 = 9

Collect like terms:

30x + 25x = 9 - 105

55x = -96

Dividing through by 55:

x = -96/55

Each face of a small cube has a surface area of 0.25 square meters. A larger cube has edges that are six times as long as the ed
bezimeni [28]
First, you need to find the length of the smaller cubes side. To do this you would need to find the square root of 0.25. then you find the volume with the new found side length of the smaller cube by cubing the new side length and once you have your volume of smaller cube right it down.
Now you need to find the big cube volume by cubing its side length. Once you have found both of these volumes you subtract the smaller cube's volume from the bigger cube's volume to get the difference in size. Hope this helps
