Answer:
3+6×(5+4÷2)-7
Step-by-step explanation:
To solve the expression use order of operations.
Right now the expression solves to:
3+6×5+4÷2-7 6* 5 = 30
3 + 30 + 4÷2-7 4 ÷ 2 = 2
3 + 30 + 2 - 7 Add and subtract left to right.
33 + 2 - 7
35 - 7
28
To make it solve to 38, add parenthesis:
3+6×(5+4÷2)-7 (5+4÷2) = 7
3+6×(7)-7 6*7 = 42
3 + 42 - 7 Add and subtract from left to right
45 - 7
38
Answer:
1/3
Step-by-step explanation:
2/3=6/9
6/9-3/9=3/9
3/9=1/3
Answer:
729/64
Step-by-step explanation:
= (3/2 a^-2b^2)^2
= 3^2 b^4 / 2^2 a^4
= 9b^4 / 4a^4
Plug in a = -2 and b = -3
= 9(-3)^4 / 4(-2)^4
= 9(81) / 4 (16)
= 729/64
B is the first table
c is the second table
a is the third table
