Unfortunately, due to the quality of your image, it's hard to tell the specifics of questions and answers. However, I can tell you how to solve these and hopefully it helps!
<em>The question asks for the slope of the line:</em>
1. Find the two points of the line that are bolded. It should be given to you. For example, (5,7) and (8,9)
2. The slope formula is:
Using my example of the points, (5,7) and (8,9), 5 could be x1, 7 would be y1, 8 would be x2, and 9 would be y2.
Then, you would plug it in the slope formula:
which equals
which equals
1.5
<em>Therefore, the slope of the line I gave you is 1.5</em>
I hope this helps you a bit! :)
Answer:
a= 73.2
b =36.6
c = 76.2
Step-by-step explanation:
Perimeter of the triangle is the distance round the triangle.
Let the 3 sides be a, b and c
Side a of the triangle is twice as long as side b. This means
a = 2b
Side c is 3 feet longer than side a. This means
c = a + 3
The perimeter of the triangle is 93 feets. Formula for finding the perimeter of the triangle is
(a + b + c)/2
Therefore,
93 = (2b + b + 2b + 3)/2
93 = (5b + 3)/2
5b + 3 = 93 × 2 = 186
5b = 186 - 3 = 183
b = 183/5 = 36.6
a = 2b = 2 × 36.6 = 73.2
c = a + 3 = 73.2 +3 = 76.2
There are 3 girls & 4 boys.
Each student makes 8 paper airplanes.
Amount of paper airplanes created by girls: 3 x 8 = 24
Amount of paper airplanes created by boys: 4 x 8 = 32
Amount of paper airplanes created in all: 3(8) + 4(8) = 24 + 32 = 56

Step-by-step explanation:
A triangles angles measure up to 180° so before finding x you must find the missing angle.
So lets make an equation:
180=22+23+a
(a is the missing angle)
So add 22+23=45
180=45+a
Subtract 45 from both sides to isolate A
180-45=45-45+a
135=a
135° is your missing angle
So now we have to find X
A straight line measures to 180° so now we subtract 135°(or a) from 180°
180-135=x
x=45
Therefore X is 45°
