54 = 2 * 3 * 3 * 3.
3 occurs 3 times so the perfect cube is 27.
Answer: n = 130
Step-by-step explanation:
The sequence is an Arithmetic progression ( AP )
The last term of the sequence is (L) is 394 with the formula
L = a + ( n- 1 )d . From the sequence, a = 7, d ( common difference ) = 3 and L ( last term ) = 394, and n = ?
Put those values in the formula above and solve for n.
a + ( n - 1 )d = L
7 + ( n - 1 ) x 3 = 394
7 + 3n - 3 = 394
4 + 3n = 394
3n = 394 - 4
3n = 390
n = 130
Answer:
2/4
Step-by-step explanation:
Change the 2 1/2 to 2 2/4
now subtract 1/4 from 2 2/4 leaving 2 1/4
Now subtract 1 3/4 from 2 1/4 in which you get 2/4
which is the answer :)
Answer:
-18v + 9w +15
Step-by-step explanation:
-3(6v-3w-5)
You can use a table or multiply each term
-3(6v) + -3(-3w) + -3(-5)
= -18v + (9w) + (15)
= -18v + 9w + 15
