Answer:
r = -4
Step-by-step explanation:
If M is the midpoint of DE, that would mean that the distance from M to D and M to E would be the same.
This creates the equation 1-8r=13-5r.
Now it's just simple algebra.
You add 8r to both sides, creating 1=13+3r. Then, you subtract 13 from both sides, getting 3r=-12. Dividing both sides by 3 and solving for r, you get r=-4.
Checking our answer, you see that 1-8(-4)=1-(-32)=1+32=33, and 13-5(-4)=13-(-20)=13+20=33.
Answer:
4 x 2
Step-by-step explanation:
number of rows is 4
number of columns is 2
Answer:
A hexagon has six sides, and we can use the formula degrees = ( number of sides – 2) × j180. Then degrees = (6 – 2) × 180 = 720 degrees. Each angle is 720/6 = 120 degrees. straight angle is 180 and that one angle of hexagon 120 so 180 - 120 = 60
answer: value of x is 60 degrees
Answer:
1.1 cm or 7.9 cm
Step-by-step explanation:
Given:
Point D mark for 4.5 cm
Distance between points D and E =3.4 cm
Find:
Location of point E
Computation:
Assume;
Point o = 0 cm mark
Point E = Point D mark - Distance between points D and E
Point E = 4.5 cm - 3.4 cm
Point E = 1.1 cm
or
Point E = Point D mark + Distance between points D and E
Point E = 4.5 cm + 3.4 cm
Point E = 7.9 cm
