Okay so.
2/5=24/60 (multiply 2/5 by 12)
2/3=40/60 (multiply 2/3 by 20)
1/4=15/60 (multiply 1/4 by 15)
Then,
Add 24/60 with 40/60 which is 64/60 after you get that you subtract by 15/60 and you get 49/60.
Hope this helps!^^
Answer:
76
Step-by-step explanation:
A + B = 127
5.80A + 4.25B = 657.55
Solve with substitution.
5.80A + 4.25(127 − A) = 657.55
5.80A + 539.75 − 4.25A = 657.55
1.55A = 117.80
A = 76
Answer:
Addition and Subtracttion
Step-by-step explanation:
The order of operations has to with a generally accepted order to follow when evaluating a mathematical expression.
PEDMAS or BODMAS is the order of operations to follow.
The two operations that are on the same level within the order of operations are addition and subtracttion
This means that, neither has a preference over the other.
