Can someone help me with this problem<br>1) n/3=2<br>2) 5t = 20
nika2105 [10]
To solve the first problem, you have to multiply both sides by 3, or 3/1.
3/1(n/3)=2(3)
3n/3=6
1n=6, or n=6.

To solve problem 2, simply divide both sides by 5.
5t/5=20/5
t=4

Hope this helps :-)

aev [14]
The sides of the square is 6 cm with a scale factor of 1.6
So the actual size will be
= 6 * 1.6
= 9.6 cm

Getting the area:
Area = s^2
Area = 9.6^2
Area = 92.16 square centimeters

Getting the perimeter:
Perimeter = 4*s
Perimeter = 4 * 9.6
Perimeter = 38.4 cm
