please mark me as brainlist please
Step-by-step explanation:
Correct option is D)
By property of similar triangle, we have
DE
AB
=
DC
BC
=
CE
AC
3
4
=
4.8
BC
=
4.2
AC
⇒ BC=6.4 and AC=5.6
Hence CA=5.6cm,DA=6.4cm
yes u multiple and divided so ans caome 150
let's say the original number is "a".
(1,5) (2,10) (3,15) (4,20) (5,25) (6,30) (7,35) (8,40) until she sells out.
Answer:
Step-by-step explanation:
18. x + 25 = 55
x = 30
19. 2x - 5 = 95
2x = 100
x = 50
20. 3x - 22 = 2x + 26
x - 22 = 26
x = 48
21. 3x - 18 + 105 = 180
3x + 87 = 180
3x = 93
x = 31
22. 19x + 17x = 180
36x = 180
x = 5
27(5) = 135
23. 5x + 40 + 2x = 180
7x + 40 = 140
7x = 140
x = 20
5(20) = 100
2(20) = 40
5(20) + 40 = 100 + 40 = 140
