Answer: 250 total kids and 140 girls
Step-by-step explanation:
%56=girls that means %44= boys that means 110 is %44 of the number of kids is 110/44*100= 2.5*100=250kids 56%=girls that means %56 of 250 which is 140 girls
((5-2)*180)/5=SPT
SPT=108
360-(108+90)=RPT
RPT=162
((n-2)*180)/n=162
162n=(n-2)*180
.9n=n-2
.1n=2
n=20
Answer:
x = -3
y = 6
Step-by-step explanation:
3x + y = -3
x = -y + 3
3x + y = -3
3(-y + 3) + y = -3
-3y + 9 + y = -3
-3y + y + 9 = -3
-2y + 9 = -3
-2y = -3 - 9
-2y = -12
y = -12/-2
<u>y = 6</u>
x = -y + 3
x = -6 + 3
<u>x = -3</u>
