Answer:
Step-by-step explanation:
we have to find if the series have a constant of proportionality by dividing the value of y by each value of x
1)
100 : 2 = 50
200 : 4 = 50
300 : 6 = 50
400 : 8 = 50
ok = y
2)
0.60 : 4 = 0.15
1.20 : 8 = 0.15
1.44 : 12 = 0.12
no = n
3)
0.15 : 1 = 0.15
0.3 : 2 = 0.15
0.45 : 3 = 0.15
0.6 : 4 = 0.15
ok = y
Answer:
You would do this problem like a normal varible problem. x=10
Step-by-step explanation:
Since 9x is a right angle the inside would also be 9x
9x+4x+10+40=180
180 because that is how much a triangle equals
combine like terms
13x+50=180
subtract 50 from both sides
13x=130
divide by 13
x=10
