Answer:

x = 3

Step-by-step explanation:

5x + 3 = 3x + 9

subtract 3 on both sides (cancels out 3) (inverse operation)

5x = 3x + 6

subtract 3x on both sides (cancels out 3x) (inverse operation)

2x = 6

divide both sides by 2 (isolates x) (simplifies)

x = 3

Louis eat 6/8 of a pizza what fraction of the pizza is left over

arlik [135]

1 whole pizza is equal to 8/8. If Louis eats 6/8 then there should be 2/8 left, if your teacher wants it simplified then you will divide both the numerator and the denominator by 2 giving you a fraction of 1/4.

? Liter equivalent to 0,000 000 000 013 cubic kilometers

Amiraneli [1.4K]

Question:

? Liter equivalent to 0.000 000 000 013 cubic kilometers

How do we do it?´

Answer:

13 liter is equivalent to 0.000 000 000 013 cubic kilometers

Solution:

Given that,

? Liter equivalent to 0.000 000 000 013 cubic kilometers

So we have to convert cubic kilometer to liter

Use the following conversion factor

$1\ km^3 = 1000000000000\ liter$

Therefore,

$0.000 000 000 013\ km^3 = 0.000 000 000 013 \times 1000000000000\ liter\\\\0.000 000 000 013\ km^3 = 13\ liter$

Thus, 13 liter is equivalent to 0.000 000 000 013 cubic kilometers
