Answer:
2700 - 2000 = 700 - 100 = 600 - 200 = 400 - 100 = 300
300 dollars
I could not see the first question so i couldn't answer.
2) Draw a horizontal line and cut it in half with a vertical angle. 4 equal quarters will form. There each quarter is 90° (right angle is exactly 90°angle)
3) Just add the two angles.
x =13+19
x= 32° (Answer)
4) We must know the other angle value in order to find x. So considering both the angles are equal,
2x = 44
x= 22° (Answer)
5) Yes, x = 80° because the line cutted is a straight line and the value of a straight line is 180°
6) Supplementary angles total 180°
Complementary angles total 90°
7)Opposite angles is equal when two straight lines intersect. So,
14x - 16 = 12x + 22
14x-12x=22+16
2x= 38
x= 19° (Answer)
8) Corresponding angles
9) 140°
Circumference= 2 times pi times radius
c=2pir
divide both sides by 2pi
c/(2pi)=r
c=12.6
12.6/(2 times pi)=12.6/2 times 1/pi=6.3 times 1/pi=6.3/pi
radius=6.3/pi=aprox (pi aprox 3.14) 2
Answer:
13x -9
Step-by-step explanation:
4x-1 + 9x-8
Combine like terms
4x +9x -1-8
13x -9
