Answer:
x=5, y=6. (5, 6).
Step-by-step explanation:
-6x+6y=6
-6x+3y=-12
---------------
simplify -6x+6y=6 into -x+y=1 and y=1-(-x)=1+x
-6x+3(1+x)=-12
-6x+3+3x=-12
-3x=-12-3
-3x=-15
3x=15
x=15/3
x=5
-6(5)+6y=6
-30+6y=6
6y=6-(-30)
6y=6+30
6y=36
y=36/6
y=6

This is how you solve it; but first of all convert the percent into a decimal;55%= 0.55
0.55x = 164 (divide by 0.55 on both sides)
x = 164/0.55
x = 298.18 (rounded to the nearest hundredth)
so 164 is 55% of 298.18(rounded)
Answer:
Step-by-step explanation:
<u>For old circular garden:</u>
take the radius as r.
then use the formula to find area of circle: πr² ......this is old garden area.
<u>For new enlarged garden:</u>
the radius is twice the old radius so, radius = 2 * r = 2r ......enlarged radius
now find area for this new garden: π(2r)² → 4πr²
In common fractions: (old garden)/(new garden)
: ( πr² ) / ( 4πr² )
: 1/4
