Answer:
4) 5
Step-by-step explanation:
3x-x+2=12
First, you combine similar terms, so 3x-x which is 2x.
Second, you subtract 2 on both sides which is going to give you 2x=10.
Finally, you divide by 2 on both sides, so the final answer is going to be x=5.
Hello,
y=2x+1
x=2y+1 exchange x and y
==>2y=x-1 solve for y
==>y=(x-1)/2
==>y=x/2-1/2
Answer A
Answer:
<u><em>15 cookies are chocolate</em></u>
Step-by-step explanation:
Well it's actually quite easy, just think about it this way. 20/4=5 since there's a 4 as the denominator in the fraction. Or there's many other ways to find the answer. At the end of the day, you'll get the same answer just some ways are harder especially compared to the one I did.
Since we divided 4 into 20, we know the answer to that is 5.
3/4=15 if you think about it in a certain way.
Therefore the answer is 15 since 3x5= 3/4 and both of those equal 15
