2n+5=20
Subtract 5 from 5 and 20
2n=15
Divide 15 and 2 by 2
n=7.5
:P
I think it’s 25%
Because 70 divided by 10 is 7
Which is then 10% so 20% is 14 then 5% is half of 7 which is 3.5
So 70 -7-7-3.5=52.5 which is 25%
L=2W-4
PERIMETER=2L+2W
58=2(2W-4)+2W
58=4W-8+2W
58=6W-8
6W=58+8
6W=66
W=66/6
W=11 ANS. FOR THE WIDTH.
L=2*11-4
L=22-4
L=18 ANS. FOR THE LENGTH.
PROOF:
58=2*18=2*11
58=36+22
58=58
B. Accuracy is if it's right or not. Precision is how many decimal places it goes out to. So it is precise but not accurate.
