Im not sure wym but i think the answer is 20
<h3><u>The value of the first number, x, is equal to 18.</u></h3><h3><u>The value of the second number, y, is equal to 90.</u></h3><h3><u>The value of the third number, z, is equal to 77.</u></h3>
x + y + z = 185
y = 5x
z = y - 13
Because we already have a value for y, we already have a value for z. We can now solve for a value of x.
x + 5x + 5x - 13 = 185
Add 13 to both sides.
x + 5x + 5x = 198
Combine like terms.
11x = 198
Divide both sides by 11.
x = 18
Because we have a value of x, we can solve for the exact values of y and z.
y = 5(18)
y = 90
z = (90) - 13
z = 77
Answer:-2/5
Step-by-step explanation:
Now the above equation can be rewritten as 5y= -2x+1
Dividing this expression through by 5, we have 5y/5 = -2x/5 + 1/5
y= (-2/5)x + 1/5
Comparing with the general equation of a line;
y = mx + c; m= gradient; C= constant along the y-axis
m= -2/5
