Answer: y=85
Step-by-step explanation: Substitute all x's in the equation with 8. y=2.5(8)+65. And solve y=85
Answer:
3x- we need to know what x is to go any further
Step-by-step explanation:
<em>2 solutions</em>
<em>X= 16</em>
<em>X=49</em>
Step-by-step explanation:
<em>original equation</em>
<em>x-11√x+28 = 0</em>
<em> Isolate</em>
<em> -11√x = -x-28+0</em>
<em> Tidy up</em>
<em> 11√x = x+28</em>
<em> Raise both sides to the second power</em>
<em> (11√x)2 = (x+28)2</em>
<em>After squaring</em>
<em> 121x = x2+56x+784</em>
<em> Plug in 49 for x </em>
<em> 11√(49) = (49)+28</em>
<em>Simplify</em>
<em> 11√49 = 77</em>
<em> Solution checks !!</em>
<em> Solution is:</em>
x = 49
<em>Plug in 16 for x </em>
<em> 11√(16) = (16)+28</em>
<em>Simplify</em>
<em> 11√16 = 44</em>
<em> Solution checks !!</em>
<em> Solution is:</em>
x = 16
Answer: 
Step-by-step explanation:
Group like terms:
Simplify the arithmetic:
Add 7 to both sides:
Simplify the arithmetic:
Simplify the arithmetic:
Divide both sides by 3:
Simplify the fraction:
Find the greatest common factor of the numerator and denominator:
Factor out and cancel the greatest common factor and the answer will be:
Rational numbers because not a whole numbe,r counting number or integer
