That will = D
There are two bags: a bag with 4 blue marbles and 6 black marbles and another one containing 6 blue marbles and <span>6 black marbles. the probability of getting a blue marble in the first bag is 6/10 or 3/5 while that on the second bag is 6/12 or 1/2. Hence the total probability of getting two marbles is c. 3/10. </span>
Solutions
Simplify <span><span>2/3</span>x</span> to <span><span>2x/</span>3
</span>
<span><span><span>2x/</span>3</span>=10
</span>2) Multiply both sides by 3
<span>2x=10×3
3) </span>Simplify 10×3 to 30
<span>2x=30
4) </span>Divide both sides by <span>2
</span><span>x=30 </span>÷ <span>2
5) </span>Simplify <span>30 </span><span>÷ 2</span><span> </span><span>to</span><span> </span><span>15
</span><span><span>x=15
Answer = 15
Also can be written as 1/15</span></span>
The answer is 4 inches. This is because the scale is 1 inch=3 feet. And when doing 12ft divided by 3ft you get 4. The 4 then represents 4 inches. Hope it helps :)
First, we can see that he used the Distributive property. Then after that, he used the Additive property. After that, he combined like terms and the used the additive property again. Finally, he used the divisive property.
