What else can I help you with?
X varies directly with y and z x equals 400 when y equals 8 and z equals 10 Find x when y equals 10 and z equals 12?
x = 5.y.z so 5.10.12 = 600
If x is inversely proportional to y and x is 60 when y is 0.5 find x when y is 12?
5/2
Find P 9 x 15 when mu equals 12 and sigma equals 2?
0.8664
What does 3x equals 12 mean?
They're asking you to find a value for x, which in this case is 4, since 3 times 4 equals 12.
What times 25 equals 300?
To find the number, divide 300 by 25. The result is 12. Therefore, 12 times 25 equals 300.
If y varies inversely as x and y equals 24 when x equals 8 find y when x is 4?
y is 12
Assume that y varies inversely as x. If y equals -6 when x equals-2 find y when x equals 5?
-6/y=5/-2 5y=12 y=12/5
X varies directly with y and inversely with z x equals 0.12 when y equals 12 and z equals 2 Find x when y equals 1200 and z equals 1?
x = 24
If y varies inversely as x and y equals 12 when x equals 6 what is k the variation constant?
If y and x are related inversely, then the equation for y can be said to be:y = k/xTo find the constant k, substitute 12 for y and 6 for x (a pair of values that are known to satisfy the equation).y = k/x12 = k/612 X 6 = k72 = kThe value of the variation constant k is 72.
If x and y are inversely proportional and x equals 13 when y equals 12 w is x when y equals 24?
26.
A varies directly as b and a equals 12 when b equals 4 What is the constant of variation?
a varies directly as b and a = 12 when b = 4. What is the constant of variation?
If y varies directly with x find the constant of variation if x equals 8 and y equals 12?
y = cx when x = 8, y = 12 so that 12 = 8c which gives c = 12/8 = 1.5
X varies directly with y and z x equals 400 when y equals 8 and z equals 10 Find x when y equals 10 and z equals 12?
x = 5.y.z so 5.10.12 = 600
F varies jointly as g h and j One set of values is f equals 18 g equals 4 h equals 3 and j equals 5 Find f when g equals 5 h equals 12 and j equals 3?
f = 54
If y varies directly as x and y equals fifteend and when x equals three find y when x equals twelve?
y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.
What times 12 equals 64?
To find what number multiplied by 12 equals 64, you would divide 64 by 12. 64 divided by 12 equals 5.33 recurring. Therefore, 5.33 recurring times 12 equals 64.
Solve by using the steps found in this section. Write your answer in exact, simplified form y is inversely proportional to z. If y is when z is 15, find y when z is 30?
k = 2 Explanation: when z varies directly proportional to x means a division c = z x where c is a constant of proportionality when z varies inversely proportional to x it means a product z y = c now with both k = z y x z = 8 ; x = 12 and y = 3 k = 8.3 12 k = 2
