Answer:
<h3>The numbers are 20 and 9 </h3>
Step-by-step explanation:
Let the first number be x
Let the second number be y
<u>For the first equation </u>
One number is 7 less than 3 times the second number is written as
x = 3y - 7
<u>For the second equation</u>
The sum of the two numbers is 29
So we have
x + y = 29
Substitute the first equation into the second one
That's
3y - 7 + y = 29
4y = 29 + 7
4y = 36
Divide both sides by 4
<h3>y = 9</h3>
Substitute y = 9 into x = 3y - 7
That's
x = 3(9) - 7
x = 27 - 7
<h3>x = 20</h3>
The numbers are 20 and 9
Hope this helps you

Answer:
y = 8.5x
Step-by-step explanation:
A proportional relation in one in which change of value of y with respect to change of value of x remains proportional. It can be represented by equation
y = kx, where k is constant of proportionality
________________________________________________
Let the relation be
y = kx
but we have a as 3 and b as 25.5
thus
substituting value of and a and b in y = kx , we have
25.5 = k*3
=> k = 25.5/3 = 8.5
Thus, equation which can represent this relation is y = 8.5x
