Answer:
Step-by-step explanation:
9/16=x/12
cross product
16x=9*12
16x=108
x=108/16
simplify
x=27/4
---------------
x-3/18=12/9
x=12/9+3/18
x=24/18+3/18
x=27/18
x=3/2
--------------------
7/11=18/x+1
18/x=7/11-1
18/x=7/11-11/11
18/x=-4/11
x=18/(-4/11)=(18/1)(-11/4)=-198/4=-99/2
x=-99/2
Answer:
4
Step-by-step explanation:
n/6 + 2 If n = 12

Answer:
I help!!
Step-by-step explanation:
1. we know that Cara lost 4 less teeth than Kathleen, and the number of teeth Kathleen lost is represented by K. So, any equation that shows K-4=C will do.(feel free to use that equation)
2. this is essentially the same as the first equation, just reversed. So use + instead of -, and instead of ending up with =C you should end up with =K
You are still using the same plugs, C, 4 and K.
3. This is basic math. Cara lost 3 teeth, Kathleen lost 4 more than cara. So, 3+4=?
Answer:
3a+6
Step-by-step explanation:
a+a+a=1a+1a+1a=3a
2+2+2=6
therefore,3a+6
<MSR = 180-136 (virtue of complementary angles) = 44°
