Answer:
x = 8/7
Step-by-step explanation:
log (X + 8) = log x + log 8
We know that log a + log b = log ab
log (X + 8) = log 8x
Raise each side to base 10
10^log (X + 8) = 10^log 8x
x+8 = 8x
Subtract x from each side
x+8-x = 8x-x
8 = 7x
Divide by 7
8/7 = 7x/7
8/7 =x
Answer:
option B is correct because
1 hectameter is equal to 10000cm
Answer:
Step-by-step explanation:
What you are being told is that 3x - 7 is twice as big as x. You can see that because ST (for example) is cut into 2 equal parts. So is UT (cut into two equal parts). So the parts of the Big Triangle (SUT) are twice as Big as the parts of the small triangle DET
So multiply x by 2
3x - 7 = 2x Add 7 to both sides
3x - 7 + 7 = 2x + 7
3x = 2x + 7 Subtract 2x from both sides
3x-2x = 7
x = 7
Given:
The area of a flower garden is 60 m².
One third of it was used for growing roses and the remaining area was divided into two equal parts.
To find:
The area of each remaining part.
Solution:
It is given that the area of a flower garden is 60 m² and one third of it was used for growing roses. So, the remaining part is:
The remaining area was divided into two equal parts. So, the area of each remaining part is:
Therefore, the area of each remaining part is 20 m².
512. If you times 8 by 8 by 8 you will get 512
