Mathematics
1 answer:
GREYUIT [131]3 years ago
3 0

Answer:

63

Step-by-step explanation:

We can easily solve this problem using algebra as follows.

Let Meteorite B be expressed as x.

We know that the combined weight is 84 tons and that meteorite A is 3 times the weight of meteorite B. That means Meteorite B is x/3.

Based on that, let's form an equation:

x + \frac{x}{3} =84\\1 \frac{1}{3} x=84\\x=63

I hope this will help you :D

Can you please help me on -5(x+2)=-(-5x+1)-x
PilotLPTM [1.2K]

Answer:

x = -1

Step-by-step explanation:

<u>Step 1:  Distribute</u>

-5(x + 2) = -(-5x + 1) - x

-5x - 10 = 5x - 1 - x

<em>-5x - 10 = 4x - 1</em>

<em />

<u>Step 2:  Solve for x</u>

-5x - 10 + 5x = 4x - 1 + 5x

-10 + 1 = 9x - 1 + 1

-9 / 9 = 9x / 9

<em>-1 = x</em>

<em />

Answer:  x = -1

Which square root is between 4 and 5
shusha [124]
Answer:
I’m not sure what you mean by divided, but the square root of 24 would be between 4 and 5.

Explanation:
I translated 4 and 5 into square roots, being the square root of 16 (4^2) and the square root of 25 (5^2).
4 is equal to the square root of 16 just as 5 is equal to the square root of 25.
Of the given square roots in the answers, only the square root of 24 was between the square roots of 16 and 25. Therefore, the square root of 24 is between 4 and 5.
