Yeah D is the correct answer
2 hours + 40 min = 160 min
160 min / 6 = 26.6666667

it's difficult because you are looking too hard. think simply. why does it tell you that angle is 40°?
Because if you follow the arrow back to where it starts you will see that exact same angle.
so now you know 1 (not m° or n°) angle inside the triangle is 40° and a complete triangle is 180°.
you also know a straight line has 180° on each side. and the line going from m° to n° splits that in half. meaning there is 90° to the right of it and 90° to the left of it. which means n° must equal 90°.
now you know you have 1 angle inside the triangle with 40° and n°=90° now you just need to find how much m° is.
add 40°+90° then Subtract from 180° to get m°.
180°-130°=50°
m°=50°

Answer:
y = x +6
Step-by-step explanation:
The line rises 1 unit for each 1 unit it goes to the right. The slope is ...
m = rise/run = 1/1 = 1
The line intersects the y-axis at y=6, so the y-intercept is ...
b = 6
The slope-intercept form of the equation of a line is ...
y = mx +b . . . . for slope m and y-intercept b. We have m=1, b=6.
y = x +6 . . . . . the equation of the line on the graph
x = - 3
y = -2
Step-by-step explanation:
3x - 8y = 7
x +2y = -7
We standardize the coefficient of one variable such that it addition will result to zero;
3x - 8y = 7
(x +2y = -7)4
Then multiply the one equation with a constant (this case 4) to get;
3x – 8y = 7
4x + 8y = - 28
We add the two equations;
3x – 8y = 7
+
4x + 8y = - 28
=
7x = - 21
x = -21 / 7
x = - 3
Now we evaluate y by replacing the value of x with -4 in one of the equation;
x +2y = -7
-3 +2y = -7
2y = -7 + 3
2y = - 4
y = -2
