Answer:
y=4x
Step-by-step explanation:
I hope this answers your question.
(35+47+42+x)/4 = 50
(35+47+42+x)=4*50
124 +x = 200
x=200 - 124
x= 76
Answer B. 76 points.
Answer: 4n-7
Step-by-step explanation:
16: 10(-9) +4 = -90 +4 = -86
17. 7^2 - 7 = 49-7 = 42
18. -9^2 - -9 = 81+9 = 90
19. 10(5) +4 = 54, 3*54 = 162
20. 3*5 = 15, 10(15) +4 = 154
Answer:
138.8 cm
Step-by-step explanation:
Angle I =180 - 89 - 38 = 53
Using sine law
i/sinI = k/sinK
180/sin53 = k/sin38
k = 138.76
