The systems of equations that could be used to solve the problem is
5n = 3d
5n = 3d3d + 5n = 4
Given:
numerator = n
denominator = d
Ratio = 3 : 5
Equation 1
n / d = 3/5
cross product
n × 5 = d × 3
5n = 3d
Equation 2
(n + 2) / (d + 2) = 3/5
cross product
(n + 2) 5 = (d + 2)3
5n + 10 = 3d + 6
collect like terms
10 - 6 = 3d - 5n
4 = 3d - 5n
3d + 5n = 4
Therefore, the systems of equations that could be used to solve the problem is
5n = 3d
5n = 3d3d + 5n = 4

The answer is NO SOLUTION
Answer:
Answer:
x= 29/11 or y= 25/11
Step-by-step explanation:
2x - y= 3 ...........equation 1
x + 5y= 14 ............equation 2
Make x the subject of the formula in equation 2
x= 14 - 5y ..............equation 3
Substitute x=14 - 5y in equation 1
2(14- 5y) - y=3
28 - 10y - y=3
Collect like terms
-10y - y=3 - 28
-11y= -25
divide both sides by coefficient of y
-11y/-11 = -25/-11
y= 25/11
Substitute y= 25/11 in equation 3
x=14 - 5(25/11)
x= 14 - 125/11
x= 29/11
Step-by-step explanation:
Well.. the equation for the interior angles of a polygon is 180(n-2). So it could possibly be 180.
Hope I could help.
To find the slope of a line, we must find the change in y values divided by the change in x values, given by the formula y2-y1/x2-x1 and represented by the variable m. We use our values from the ordered pairs to compute the slope, as follows:
m = (5-1)/(4-2) = 4/2 = 2
Therefore, the slope is 2. Because the slope is positive, this means that the line is rising.
Hope this helps!
