Answer:46
Step-by-step explanation:
Use BODMAS to solve this
First is to open the innermost bracket
6+(4x(5+(10÷2)))
6+(4×(5+5))
Then the next bracket
6+(4×(10)
Open the next bracket, then multiply before adding
6+40
=46
2.00 - 1.50 = 0.50
0.50 - 1.75 = -1.25
Solution: he owns $1.25
Answer:
x = 11
Step-by-step explanation:
From the diagram, we find,
(2x - 16) + (x - 8) = 9
=> 2x - 16 + x - 8 = 9
=> 2x + x - 16 - 8 = 9
=> 3x - 24 = 9
=> 3x = 9 + 24
=> 3x = 33
=> x = 33/3
=> x = 11
