22a+15c=228
a+c=11
a=11-c
22(11-c) + 15c = 228
242-22c + 15c = 228
-7c=-14
C = 2 (two children)
Remember how a + c = 11
a + 2 = 11
A= 9
9 adults, 2 children.
7/20 because it equals 35% which is what is left of the company because the first one owns 1/4 25% the next owns 2/5 40%.
Direct variation is of the form
y= mx
2x-4y = 0
2x = 4y
4y = 2x
y = 2/4 x
y =(1/2)x
which is indeed of the form y = mx
Hence, the equation does represent direct variation.
in y= mx,
the constant of variation is m
so in y = (1/2)x
the constant of variation is 1/2
Answer:
L, W, Z, and O all have the value of 58 cause they are either parallel to 58 or parallel from an angle that equals 58. The rest of the angles can be found my doing 180-58=122. 122 is the value of all the remaining angles.
4(-1) + 10
-4 + 10
f(-1) = 6
