6x-6=8x
subtract 6x from both sides
-6=2x
divide both sides by 2
x= -3

14
Step-by-step explanation:
Arithmetic expressions are best evaluated using a reliable calculator. The Google calculator always follows the Order of Operations, so can give you a good answer to such questions.
(1/4)^-2 - (5^0)(2)(1^-1)
= 16 - (1)(2)(1) . . . . evaluate the exponents first
= 16 -2 . . . . . . . . . evaluate the product next
= 14 . . . . . . . . . . . finally, evaluate the sum
___
The rule of exponents is ...
a^-b = 1/(a^b)
Answer:
h(-8)= -14
Step-by-step explanation:
h(-8)= -2(-8 + 5)^2 + 4
h(-8)= -2(-3)^2 + 4
h(-8)= -2(9) + 4
h(-8)= -18 + 4
h(-8)= -14
Answer:
Let x be the number of tickets sold to adults and y the number sold to students:
x + y = 315. But we know that y was double x, then :
y = 2x
Plug the value of y (in the 1st equation) by 2x:
x+ 2x = 315
3x = 315
and x = 105 (which is the number of tickets sold to adults
