First round 6254 to 6000 then multiply it by 2.
6,254=6,000x2=12,000
If you need help on the multiplying bit here is how you do it:
First take the whole numbers so 6 and 2. Next multiply them. 6x2=12. Then all you do is add the zeros. So in this case there are three zeros so 12,000 is your estimated answer.

George weighs 60 pounds less than his older brother. Together they weigh 240 pounds. How many pounds does George weigh?

lyudmila [28]

Easy Algebra question!

Let's use "x" as a variable.

The equation would be x+x+60 = 240 with "x" being George's weight.

Subtract 60 from both sides and you get 2x = 180.

From there you divide both sides by 2, getting x=90.

"x" is George's weight, so he weighs 90 pounds.

A smaller square is located inside a larger square. the length of the smaller square is 7 cm, and the length of the square is 12

patriot [66]

Let S=larger square side and s=smaller square side. The area between the larger and smaller is simple the larger area minus the smaller area. The area of any square being s^2. So our remaining area is:

A=S^2-s^2

A=144-49=95 cm^2
