Unit rate just means whatever measurement per ONE unit. If you were baking a batch of 12 cookies and you needed one cup. The unit rate would be 1/12cup of flour per ONE cookie
Answer:
18b-4x-5y-26
Step-by-step explanation:
-4(x-2)-5(y+2)+(-3)(8-6b)
-4x+8-5y-10-24+18b
-4x-5y-26+18b
18b-4x-5y-26

Answer: x = 7</h3>
Explanation:
Segment addition postulate
CD+DE = CE
this basically is the idea of gluing smaller pieces together to get a larger structure. We can go in reverse to break up a large item into smaller bits. This is assuming there is no leftovers, overlaps, or parts wasted/lost.
CD = 9
DE = 3x+6
CE = 36
----
CD+DE = CE
9+3x+6 = 36
3x+15 = 36
3x = 36-15
3x = 21
x = 21/3
x = 7
-----
If x = 7, then
DE = 3x+6 = 3*7+6 = 21+6 = 27
and
CD+DE = 9+27 = 36 = CE
confirming our answer
Answer:
20+5x=
Step-by-step explanation:
6a+16
Explanation:
If there's just a variable, there's an understood 1 in front of it. So what that really says is:
7a-1a+16
So, you combine the a's. 7a minus 1a is 6a. Same as 7-1,but you have a variable stuck on the end of it.
6a+16
