To find the slope of a line use the formula m=rise/run to do that all you have to do is take two points from the line
Given that:
Perimeter=194 cm
Width=w
Length, L= 4w-3
Formula for perimeter of rectangle:
P=2(L+W)
Put values
194=2(4w-3+w)
194=2(5w-3)
Divide both sides by 2.
97=5w-3
Add 3 to both sides
100=5w
w=20
So length= 4 (20) -3 = 80-3 =77 cm
and width= 20 cm
Answer: Length=77 cm and width=20 cm
13 < 2t + 3 < 27
13<2t+3 2t+3<27
13-3<2t 2t<27-3
10<2t 2t<24
10/2<t t<24/2
5<t t<12
5 < t < 12
Would me first one A because I just in the math and it should be right!
18. 12/4 =3, 36/12 =3 the ratio is 3
19. 108/162 =0.667, 72/108= 0.667 the ratio is 0.667 or 2/3
20. 2/3 / 4/3 = 1/2, 1/3 /2/3 = 1/2, the ratio is 1/2
