First re-write the problem and distribute the negative... 7x+3 -2x-1.
Then combine like terms as so... 7x -2x= 5x and 3 - 1= 2.
Re-write once more... 5x+2.

Which is bigger, <br> a) 70% of 300 <br> b) ¼ of 600?<br> ∞Δ∞
Artist 52 [7]
Since 300 is 100%, you treat it as such.

300/(100/70) = 210 (rounded)


You do a similar thing for 600

1/4 of 100 is 25
100/25 = 4
600 / 4 = 150



70% of 300 is more.

What is the total perimeter of the pitch and seating area?
natima [27]
1m = 100 cm

so
40 m = 4,000 cm
25 m = 2,500 cm
10 m = 1,000 cm

perimeter of big rectangle = 2(4,000 + 2000) = 12,000 cm
perimeter of small rectangle on the left: 2(2,500 + 800) = 6,600 cm
perimeter of small rectangle on the right: 2(1,000 + 800) = 3,600 cm
perimeter of circle = πd = 3.141593 x 200 = 628.32 cm

total area of the pitch and seating area :
=  12,000 + 6,600 + 3,600 + 628.32 = 22,828.32<span> cm

answer
</span>22,828.32 cm<span>
