Answer:
No solution.
Step-by-step explanation:
1-2k+5k<u><</u>-4+3k Combine like terms on each side wherever you can.
1+3k<u><</u>-4+3k Subtract -3k on both sides (it's less confusing when you get
<u>-3k -3k</u> rid of the variable first).
1<u><</u>-4 1 is not less than or equal to -4, so there is no solution.
I hope this helped you out!! Have a great day (*^3^)╭
Answer:
25,
8:5
4:3
Step-by-step explanation:
you have to model it as a system of equations.
first, we know there are a total of 65 children, boys and girls. so

we also know there are 15 more boys than girls so

now, we can plug the second equation into the first to get

so

if g = 25, b must = 40, because it is g+15.
the ratio will be 40 boys to 25 girls. 40:25 or 8:5 if you simplify.
if there are 5 more girls, g = 25+5 = 30, so the ratio is 40:30 or 4:3.
