A number raised to an exponent is that number multiplied by itself that number of times.
17^3 = 17 x 17 x 17 = 4913
The answer is B.
2/3x - 1/2y = 3 |multiply both sides by 6
4x - 3y = 18
1/2x + y = 5 |multiply both sides by 2
x + 2y = 10
Answer: 4x - 3y and x + 2y = 10.
8 blocks because 2/10=1/5 so if they total 4/5 then 2/10+2/10+2/10+2/10=8/10=4/5
6 times 4 is 24, divided by 2 is 12, minus 1 is 11, plus 5 is 16.
