Answer:
22.1 or 22
Step-by-step explanation:
Y + 1 varies√x
Y + 1 = K√x ( k is costant)
so we solve for K
given: 14 + 1 = K√27
15 = K√27
divide both sides by √27
15/√27 = K
to find the value of y
y + 1 = 15/√27 (8) : substitute K for 15/√27
Y + 1 = 120/√27
i.e Y = 120/√27 - 1
Y = 23.1 - 1
Y = 22.1 or 22
Get x by itself
add 16 to both sides, so 4x = 16
divide both side by 4 and x =4
Answer:
a) 40
b) 80
c) 77
d) 48
Step-by-step explanation:
To find the missing numerator, multiply the equation by the denominator of the fraction with the missing numerator.
a) (10/15)(60) = (x/60)(60)
40 = x
__
b) (x/180)(180) = (4/9)(180)
x = 80
__
c) (7/11)(121) = (x/121)(121)
77 = x
__
d) (x/144)(144) = (2/6)(144)
x = 48
Answer:
<h3>39.6</h3>
Step-by-step explanation:
collecting like terms we have:
5x-2x=-1+42
equating the terms..we have:
3x=41
divide both sides by the Co-efficient of x:
3x\3=42\3
x=39.6
It is actually the top one on the second picture because if you were to rotate it 180 degrees, it would end up on the same points
