From the given statement the unknown number is found to be - 1
The given statements can written in algebraic form as follows;
the unknown number = x
the number is multiplied by 6 = 6x
four less than twice the same number = 2x - 4
then, from the given statement the final equation equation becomes;
6x = 2x - 4
This unknown number can be solved by collecting similar terms together;
6x - 2x = -4
4x = -4
divide through by 4

Thus, the unknown number is - 1

Answer:
This is a curve linear would show the turning points clearly.
With bar graph we can also show changes but not turnng points a sthe description shows.
Step-by-step explanation:
In the context of curve fitting, a linear curve is a curve that has a linear dependence on the curve parameters. Examples of linear curves are: lines, polynomials, so where they increase the points can also show a line of fit where least amounts would stand out below the line of fit.
Answer: room 101 and room 107
Step-by-step explanation:
In room 101, the ratio of boys to girls is 16:12. This is further simplified to its lowest fraction by dividing by 4. It becomes 4:3
In room 104, the ratio of boys to girls is 20:9. This cannot be further simplified to its lowest fraction.
In room 107, the ratio of boys to girls is 12:9. This is further simplified to its lowest fraction by dividing by 3. It becomes 4:3
Therefore, room 101 and room 107 have the same ratio.
2 1/7 is a mixed number BUT it is also a rational number.
Turning this into a improper fraction, you'd get 15/7
15/7 = 2.14285...
Repeating decimals are rational numbers
You answer would be C I hope this helps........
