This question involves direct proportion which has the formula (y=kx) where y and x are the values which are proportional and k is the constant of proportionality.
The constant of proportionality is basically the value that stays the same even if the x and y values change.
In this case, the constant of proportionality would be 3/7.
Answer:
Y = 12
Step-by-step explanation:
3/9 = 4/y
By cross multiplying, we get
3*y = 4*9
3y = 36
Y = 12
Answer:
x=12, y=6
Step-by-step explanation:
Very simple!
Just substitute 0 for y and solve for x!
(anything times 0 equals 0!)
Now you can do the same thing but substitute 0 for x!
Hope this helps!
Let me work this out really quick and I'll get back to you
Answer:
9) x = 89°
10) x = 118°
11) x = 145°
12) x = 40°
Step-by-step explanation:
9) 180-91 = 89
10) x = 118° because it is alternate interior to 118
11) x-30 = 115, x = 145
12) 4x-15 = 145, 4x = 160, x = 40
