Answer:
4/15
Step-by-step explanation:
to find out the portion that is shaded we can do the following:
1 - (1/3 + 2/5)
now we want a common denominator, we can use 15:
15/15 - (5/15 + 6/15) → 15/15 - 11/15
the answer is 4/15
Answer:
N+F=42 & F+3N=70 System Solved: Natalie is 14 and Fred is 28
Step-by-step explanation:
Using variables N=natalies age and F=Freds age
N+F=42 ----> N=42-F (take this and plug it into the other equation)
F+3N=70 so F+3(42-F)=70 [simplify] F+126-3F=70 [further simplify]
-2F=-56 [divide -56 by -2] F=28 [then plug this number into the orig. equation]
So N+28=42 or N=14.
