Answer:One-half of a number added to itself equals twice the difference of the number and four.
Step-by-step explanation:
Step-by-step explanation:
b^2-4b+3=0
b²-3x-b+3=0
b(b-3)-1(b-3)=0
(b-3)(b-1)=0
either
b=3 or b=1
.
2n^2 + 7 = -4n + 5
2n²+4n+7-5=0
2n²+4n+2=0
2(n²+2n+1)=0
(n+1)²=0/2
:.n=-1
.
x - 3x^2 = 5+ 2x - x^2
0=5+ 2x - x^2-x +3x^2
0=5+x+2x²
2x²+x+5=0
comparing above equation with ax²+bx +c we get
a=2
b=1
c=5
x={-b±√(b²-4ac)}/2a ={-1±√(1²-4×2×5)}/2×1
={-1±√-39}/2
B 11 in will be your answer!!!
Y= 2/3x + 10 (or 11?) is the equation
<h2>
Answer:</h2>
<u>The cost would be </u><u>$15.86</u>
<h2>
Step-by-step explanation:</h2>
The cost of 1 steak is $6.10
The cost of 2 3/5 steaks will be
Cost of 2 3/5 steaks = 6.10 * 2 3/5
Cost of 2 3/5 steaks = $15.86
