Answer:
D) DA=ES
Step-by-step explanation:
Use triangles and CPCTC
Well you have to do PEMDAS
So we have an exponent so that will turn into a positive X
X+4x=10
So now we combine our X's together to get 5X=10
Now we divide both sides by X which gives us 2
Sorry read the problem wrong
Ask questions if you still need help :)
I think you are supposed to make the fraction equivalent so you know that 27/9 is 3, so you would do the same thing whatever number is supossed to be under 17 needs to equal to 2 when divided by 9. So you should probably know that 3 * 9 is 18 so x needs to be a number that when subtracted by 5 gives you 18. So x=23. Hope this is right and it helps!
Let's call this unknown number, x.
So we know that 4 and this number, x, are going to be added together and 6 is going to be subtracted from it. Therefore we can write the expression:
Since we cannot proceed any further without knowing either the value of x or what the expression equals, this is as simplified as it can be.
80=2m means that m=40
i figured this out by getting rid of the 2 by dividing both sides by 2
