Answer:
x < - 1
Step-by-step explanation:
Given
5x + 8 < 3(x + 2) ← distribute
5x + 8 < 3x + 6 ( subtract 3x from both sides )
2x + 8 < 6 ( subtract 8 from both sides )
2x < - 2 ( divide both sides by 2 )
x < - 1
Answer:
200
Step-by-step explanation:
W - the width
l - the length
P = 6984
P = 2w + 2l
l = 3w
substitute
2w + 2 · 3w = 6984
2w + 6w = 6984
8w = 6984 |:8
w = 873
l = 3 · 873 = 2619
Answer: the length = 2619 and the width = 873
Step-by-step explanation:
iii=90
41+i=90(opposite angle)
i=90-41
i=49
26+ii+49+41=180(straight line angle)
116+ii=180
ii=180-116
ii=64
50+25+iv=26+64(opposite angle)
75+iv=90
iv=90-75
iv=15
55+i+55=180(straight line angle)
110+i=180
i=180-110
i=70
ii=55(alternative angle)
