So thi sis really simple since you have an equal sign so
(n/3)-(5n/6)=1/3
to subtract fractions, make the bottom number the same
n/3 times 2/2=2n/6
(2n/6)-(5n/6) or (2n-5n)/6 so
-3n/6=1/3
multiply both sides by 6
-3n=6/3=2
-3n=2
divide both sides by 3
-n=2/3
mmultiply boht by -1
n=-2/3
tada
n=-2/3
Answer:
I belive it is (40x10)+(40x7)+(3x10)+(3x7)
Step-by-step explanation:
Nth term of an arithmetic sequence is given by
an = a + (n - 1)d
Here, a1 = 24, a2 = 56 and a3 = 88
d = a2 - a1 = 56 - 24 = 31
Therefore, the explicit formula is given by an = 24 + (n - 1)31 = 24 + 31n - 31 = 31n - 7
i.e. an = 31n - 7
Answer:
1/4 of the cake.
Step-by-step explanation:
Since he ate 1/3 of 3/4 of the chocolate cake, we will need to multiply fractions to solve this.
Therefore, he ate 1/4 of the entire cake.
