Answer:-3/2
Step-by-step explanation:
4n-6=-12
4n=-6
n=-6/4
n= -3/2
To find LCM
factor and eliminate ones already represented
1=1
2=2
3=3
4=2*2
5=5
1*2*2*3*5=60
ST is a midsegment, which tells you that BD=2(ST) or ST=½BD. Use that to substitute the values and find ST.
BD=2(ST)
29+x=2(2x+31)
29+x=4x+62
29=3x+62
-33=3x
x=-11
Now that we know x, we can substitute that into 2x+31 to find ST
ST=2x+31
ST=2(-11)+31
ST=-22+31
ST=9
If half of Karen's collection (4) is 1/3 of Mary's, and half of Karen's collection is 2, then 2 x 3 is how many Mary has, right? Once you know how many books Mary has, you can add how many Karen has to get your answer.
Well, it's simple. There are 3 zeros in 1,000. Just add 3 zeros. You get 123679882652000
