Answer: Read below!!! (>XD)
Step-by-step explanation:
168 x 0.18 = tip amount given = $30.24
168 x 0.06= tax
Even more simple method
168 x 1.06 = total including tax = 178.08
30.24+178.08=total paid for dinner including tax and tips
= 208.32
Answer:
x=14
Step-by-step explanation:
1.subtract 72 from 86
2. add 3 to -2
3. get the X on one side
We have that
x - 3y = 12 and -x + y = 4
We add the 2 equations together
x - 3y + (-x + y) = 16
-> -2y = 16
-> y = -8 (1)
We plug y = -8 into -x + y =4
-> -x - 8 = 4
-> -x = 12
-> x = - 12 (2)
From (1) and (2) we could conclude that the answer is B
<h2>Answer with step-by-step:</h2>
(28.-5.199-2.)228
<em>Subtract 5.199 out of 28 to get 22.801</em>
(28.-5.199-2.) * 228
<em>Subtract 2 of 22.801 to get 20.801</em>
20.80 1 * 228
<em>Multiply 20.801 and 228 to get 4742.628 </em>
4742.628<em> </em>
<h2>The answer if you need to factor it:</h2>
3*11*19*31*61/2*5^3 = 4742 157/250 = 4742.628

The line of symmetry passes through the vertex of the parabola. The x coordinate of the vertex is found with the formula <span>x=−<span>b<span>2a</span></span></span> for the equation of the form <span>y=a<span>x2</span>+bx+c</span>.
In this example, <span>a=1</span>, <span>b=10</span> and <span>c=25</span>
<span>x=−<span>10<span>2⋅1</span></span>=−5</span>
Because the line of symmetry passes through the vertex, the equation of the line is <span>x=−5</span>.
