Answer:
D
Step-by-step explanation:
1/25 is the same thing as 
. So, u wantn to find whcih answer choice does not equal that. You can use the exponent multiplication rule, where x^a times x^b equals x^a+b.
for example, answer choice A would be 5^(3+-5) which is 5^-2.
the only choice that does not equal 5^-2 is D because it equals 5^2
X = number of students who are members.
<span>19-x is the number of people who are not members.</span> x number of people paid $11 for tickets and (19-x) number of people paid $13.$11x+$13(19-x)=$209 for the total cost of the tickets.
$11x+ $247-$13x=$209 $11x-13x = $209 - $247
$-2x = $-38
divide -2 by both sides
x=19, meaning that all of the students are members.
Answer: 10 or -10
Step-by-step explanation: 3x + 12 = -18
-12 both sides then you get 3x = -30 divide by 3 which equals x = 10 or -10
20 x 1.151 would be 23.02 but rounded it would be 23 I think
Answer:
8 x 4 - (2 x 3 + 8) / 2 = 25
