Answer:

Step-by-step explanation:

Start by removing the brackets.

Left Brackets

30(1/2 x - 2)

30*1/2 x - 30*2

15x - 60

Right Bracket

40(3/4 y - 4)

40*3/4 y - 4*40

10*3 y - 160

30y - 160

Now put these 2 results together.

15x - 60 + 30y - 160     Combine the like terms.

15x + 30y - 220            That's one answer Others are possible.

5(3x + 6y - 44)

ludmilkaskok [199]
In the given mathematical value of 51, 487 to round off this number to the nearest thousand, we can elaborate the number values using the expanded form to clearly see the order position: <span><span>1. </span><span> 50, 000 = ten thousands</span></span> <span><span>2. </span><span> 1, 000 = thousands</span></span> <span><span>3. </span><span> 400 = hundreds</span></span> <span><span>4. </span><span> 80 = tens</span></span> <span><span>5. </span><span> 7 = ones</span></span> Now we can observe the numerical value of 51, 487 than 1, 000 is the number in which belongs to the thousands’ position hence since the nearest number is 400 the value will be 51, 000.
