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:
x=4.47
Step-by-step explanation:
this is the answer
Answer:
Explanation:
f(3) = (3 - 1) • 3/2
f(3) = 2 • 3/2
f(3) = 3
f(4) = (4 - 1) • 3/2
f(4) = 3 • 3/2
f(4) = 9/2
f(5) = (5-1) • 3/2
f(5) = 4 • 3/2
f(5) = 6
f(6) = (6-1) • 3/2
f(6) = 5 • 3/2
f(6) = 15/2
f(7) = (7-1) • 3/2
f(7) = 6 • 3/2
f(7) = 9
Answer: 1/5 or 0.2
Step-by-step explanation:
STEP 1⇒1 1/5 = 1 · 5 + 1/5 = 5 + 1/5 = 6/5
STEP 2⇒6/5 - 2/5 = 6 - 2/5 = 4/5
STEP 3⇒4/5(-3/4) = 4 ·(-3)/5 · 4 = -12/20 = -3/4
STEP 4⇒-3/5 · 3 = -3 · 3/5 · 1 = -9/5
STEP 5⇒-9/5 ÷ (-9) = -9 · 1/5 · 9 = 9/45 = 1/5
D is the answer because if you calculate the answer correctly. that will be so.
