A)
Since 5 of the books are new, that means that the other books are used. So, there are 11-5=6. The ratio would be 5:6.
b)
The ratio is 6:11. You get the 6 from the above problem.
Hope this helps!
Answer:
B:J:S
6:8:10
6+8+10= 24 parts all together
Sarah has $50 and equals 10 parts. So, each part is worth $5. (50/10=5)
Thus, Ben receives 6 parts, with each part being $5. So, Ben gets $30. (6x5=30)
Answer: 2(3x + 2y) and 6x + 4y
Step-by-step explanation:
Hi, to answer this question we have to solve the expression.
2(2x + 4y + x − 2y)
First we have to simplify the expression within the brackets.
2 (2x + x +4y -2y)
We have the first equivalent expression. Now to obtain the second expression we apply distributive property:
2 (3x) + 2 ( 2y)
In conclusion 2(3x + 2y) and 6x + 4y are equivalent expressions to 2(2x + 4y + x − 2y).
Feel free to ask for more if it´s necessary or if you did not understand something.
You substitute the equation and see if it works. Also, the first one that you answered is wrong.
