We will solve it by this way-
2 m and 3 b can do a work in 8 days.
Then 3 m and 4 b do it in how many days.

x=2*3*8/3*4
x=2*8/4
x=2*2
x=4 days
Answer: 50
Step-by-step explanation:
I am rounding it to 1 significant figure.
9.8 = 10 (round up when the last digit is 5, 6, 7, 8 or 9)
5.2 = 5 (round down when the last digit end with 0, 2, 3 or 4)
So it now is 10 x 5 = 50
The answer to the equation 1/3(6x-15)= 1/2(10x-4) is D. -1
Answer:
a) 7:10
Step-by-step explanation:
An example of this would be having seven blue marbles and three red marbles in a jar. If you randomly select one, the chance of that marble being blue is seventy, because 10 (total number of marbles) divided by seven (number of blue marbles) is 0.70, and if you convert this to a whole number (by multiplying it by 100) you get 70.
