To solve, you start with distributive property and multiply 7 by n and 3 for
7n-21<-63 the you get the 7n alone by adding 21 to -63 and the 21 for 7n<-42. now you divide 7 by itself and 42 for n<-6
It would be -4. subtracting a positive is the same as adding a negative
<span>C. 8:32
2/16 = 1/4
2:4=1:2
6 to 20 = 3:10
8:32 = 1:4
12 to 64 = 3: 16</span>
1/5×m+2/3-2=m-2/5
Multiply both sides by 15:
3m+10-30=15m-6
12m=14
m=14/12
m=1.16
