The numbers are 1 and 18
<em><u>Solution:</u></em>
Let the smaller number be "x"
Let the larger number be "y"
Given that smaller of two numbers is five less than the larger number
smaller number = one - third of larger number - 5
3x = y - 15
y = 3x + 15 ------- eqn 1
Half the larger added to the smaller is 10
y + 2x = 20 ------- eqn 2
Let us solve eqn 1 and eqn 2
Substitute eqn 1 in eqn 2
3x + 15 + 2x = 20
5x = 20 - 15
5x = 5
<h3>x = 1</h3>
From eqn 1,
y = 3(1) + 15 = 18
<h3>y = 18</h3>
Thus the numbers are 1 and 18
6/11=x/33 is not a proportion because they aren't equal to each other.
Answer:what is 86-50=36 us the tax rate
Step-by-step explanation:
Answer:
8%
Step-by-step explanation:
new length = 110% x 30 = 33cm
new width = 105% x 20 = 21cm
new perimeter = 2(33 + 21) = 108cm
old perimeter = 2(30 + 20) = 100cm
percentage increase = 8/100 x 100% = 8%
