Answer:
Step-by-step explanation:
-6x + 3y = -7
to find the x intercept, sub in 0 for y and solve for x
-6x + 3y = -7
-6x + 3(0) = -7
-6x = -7
x = 7/6 <=== ur x intercept is (7/6,0)
to find the y intercept, sub in 0 for x and solve for y
-6x + 3y = -7
-6(0) + 3y = -7
3y = -7
y = -7/3 <=== ur y intercept is (0,-7/3)
Ok! So first, 2 hours are 120 minutes and 55 + 35 = 90
120 - 90 = 30
So the answer is A. Cindy spends 30 minutes on History

HERE'S HOW TO DO IT :)
A composite figure is made up of several simple geometric figures such as triangles, rectangles, squares, circles, and semicircles.
<u>To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.</u>

<u>HERES WHAT WE KNOW ABOUT COMPOSITE FIGURES:</u>
<u>Composite Figures. A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape). For example, figure ABCD is a composite figure as it consists of two basic figures</u>

The x value will be 109°. The straight line formed a 180° angle. Solving the equation yields the angle.
<h3>What are supplementary angles?</h3>
Supplementary angles are two angels whose sum is 180°. When a straight line intersects a line, two angles form on each of the sides of the considered straight line.
Those two-two angles are supplementary angles in two pairs. That is, if two supplementary angles are adjacent to each other, their exterior sides form a straight line.
The straight line formed a 180° angle. The resulting equation is as follows:
⇒x+42°+29°=180°
⇒x=109°
Hence, the value of the x will be 109°
The complete question is:
