The answer is 8 (8 x 8 x 8 = 512)
Answer:
It’s not
Step-by-step explanation:
1/324 is betwen 1 and 0, -324 is 324 numbers below zero
Step-by-step explanation:
5n = 44 + 2(n+2)
5n = 44 +2n+4
5n-2n = 48
3n = 48
n = 16
the integers are : 16 and 18
Answer:
0.4x10'20
Step-by-step explanation:
for the scientific notation u need to move the decimal to make a small number.
0.0000000000000000000004 ---> 0.4
move the decimal 20 spaces to the right
(formula:(number times 10(expontent 'the moved spaces'))
0.4x10'20
(the 20 is the expontent)
A + c = 824 represents number of tickets to sell
20a + 12c = 13,344 represents cost of each type of ticket
multiply equation 1 by -12 to cancel the variable 'c' and solve for 'a'
-12(a + c = 824)
-12a - 12c = - 9888
20a + 12c = 13,344 add equations together
-----------------------------
8a = 3456 divide both sides by 8
a = 432
To find children's tickets substitute adult numbers back into equation 1.
a + c = 824
432 + c = 824
subtract 432 from both sides
c = 392
adult 432, children 392
