B because you don’t know exactly how many times she’s gonna grab the marbles
(3)(17.25) = 51.75; he spent $51.75
Because everything in the problem is positive, no negative numbers are needed.
Answer:
y =0
Step-by-step explanation:
From the equation;
8³ × 8⁻⁵×8^y = 8⁻²= 1/8²
From the laws of indices;
aⁿ×aⁿ = a^2n
Therefore;
8³ × 8⁻⁵×8^y = 8^(3+-5+y)
8^(-2+y) = 8^-2 ; but the bases are the same and thus the exponents are the same;
-2 + y = -2
y = 0
Answer:
1a
Step-by-step explanation:
8000*0.25=2000
2000*0.25=500
500*0.25=125
