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
Answer:
number 1 + number 2 + number 3 = 15
Number 1 = x + 12
Number 2 = x - 12
Number 3 = x
(x + 12) + (x - 12) + x = 15
x + 12 + x - 12 + x = 15
x + x + x +12 -12 = 15
3x = 15
x = 15/3 = 5
Check:
Number 1 = 17
Number 2 = 5 -12 = -7
Number = 5
number 1 + number 2 + number 3 = 15
17 + (-7) + 5 = 15
10 + 5 = 15
15 = 15
Answer is 5
Step-by-step explanation:
Answer: 100
Step-by-step explanation:
Anything below 50 would be rounded down to 0. Anything over 50 would be rounded up to 100.
I'll use the same notation as the other one:
3(y-6)<4(y+5)
I'm going to clean this up a bit by distributing:
3y-18<4y+20
Now, subtract 3y from both sides:
-18And now, subtract 20:
-38So y is greater than or equal to -38
Hope this helps!
