Answer:
the answer is A.
Step-by-step explanation:
Answer:
4x-10
Step-by-step explanation:
Multiply both by 2, 2x times 2 is 4x, and 5 times 2 is 10, so it becomes 4x-10.
A and b can do a piece of work in 12 days. If a alone have to finish the job among b and c so
A and b=12
A (24 days alone without b)
So if b and c 15 days and c 20 days. If a have to do all I would add 24 and 15 and 20 which would be 59 days
3000 + 70 + 2
It's basically everything that is added to get that number. You do not need a 100's place because a 0 is holding that spot.
To solve the problem, do the problem in the parenthesis () then do your answer with the numbers outside the ().
(8-3) = 5 x 3 = 15
(6 + 4) = 10 / 2 = 5
(6 - 4) = 2 / 2 = 1
(6 x 4) = 24 / 2 = 3
Um... part of the (6 4) doesn't make sense... What goes between the numbers? Plus, minus, multiply or division sign? Please tell.
But, I already got you started off and I'll let you figure out the rest. (If you can not figure out the rest, please tell me what sign is between the 6 and 4 in (6 4) and then I'll give you the answer and a better explanation.)
I hope this helps! :D
