You divide a number by 3 add 6 then subract 7 the result is 4

Answers

Answer 1

Answer: $(n)/(3)$ +6 - 7 = 4
Subtract 6 from each side of the equation

$(n)/(3)$ -7 = -2

Now add 7 to both sides of the equation.

$(n)/(3)$ = 5

Finally multiply by 3 on both sides to undo the division

n= 15

Check
15/3 + 6 -7 = 4
5 + 6 -7 = 4
11- 7 = 4
4 = 4

Helen's house is located on a rectangular lot that is 1 1/8 miles by 9/10. Estimate the distance around the lot.

Answers

You round 1 1/8 to 1 and 9/10 to 1 (since you are estimating) and then you add 1+1+1+1, which is 4 because to find perimeter you add the lengths and the widths together.

Tim had 4 paper fraction pieces, each of thirds, fourths, sixths, and twelfths. He did not have enough pieces to show both 2/4 and 1/3 as equivalent fractions with the same denominator. How could he form enough pieces by making 1 cut with a scissors

Answers

I think that poor boy Tim has enough pieces(1/3, 1/4, 1/6, 1/12) and does not need to cut anything.

1/3 + 1/6=4/12 + 2/12=6/12=2/4

1/4 + 1/12=3/12 + 1/12= 4/12= 1/3or 1/4
