I think the answer is $6.30 , because you have to add. So 2.80 multiple by 2 would be 5.6 and after that you divide 2.80 by 4 since .25 it's a quarter of the whole so that gives you 6.3.
There are two methods to do this:
1. 2(x + 1) = 38
2*x + 2*1 = 38 (Expand the bracket)
2x + 2 = 38
2x = 36 (Subtract 2 from both sides)
x = 18 (Divide each side by 2)
2. 2(x + 1) = 38
(x + 1) = 19 (Divide each side by 2)
x = 18 (Subtract 1 from each side)
false 2z + 10= 12z
2(z + 5) = 10z
The answer is C.
x^2 + z = 103x^2 + 22 = 103*Subtract both sides by 22*x^2 + 22 - 22 = 103 - 22x^2 = 81*square root both sides to find x*√x^2 = <span>√81</span>
<span>x = +- 9</span>
The slope-intercept form:
y = mx + b
m - slope
b - y-intercept
We have the line y = 2x - 5.
The parallel lines have the same slope. Therefore we have y = 2x + b.
Put the coordinates of the point B(8, 6) to the equation:
6 = 2(8) + b
6 = 16 + b <em>subtract 16 from both sides</em>
-10 = b → b = -10
The equation of a line: y = 2x - 10.
Put the coordinates of the point A(n, 4) to the equation:
4 = 2(n) - 10 <em>add 10 to both sides</em>
14 = 2n <em>divide both sides by 2</em>
<h3>7 = n → n = 7</h3>
