The answer is Product of Powers Property.
Answer:
x = 12
Step-by-step explanation:
Given x varies as the cube root of y then the equation relating them is
x = k
← k is the constant of variation
To find k use the condition x = 6 when y = 8, thus
k =
=
=
= 3
x = 3
← equation of variation
When y = 64, then
x = 3 ×
= 3 × 4 = 12
Transpose the y into the left part of the equation and the 20 should be on the right
y= -20x
Answer:30x+30y+30
Step-by-step explanation:
30(x + y + 1)
Answer:
abdul has 15
keiko has 22
bob has 45
Step-by-step explanation:
82= a+7+3a+a
75=a+3a+a
75=5a
15=a
15=abdul
15+7=keiko
3(15)=bob
