What is 8k -1 equals 15?
k=2.
What is a number k divided by 15 equals 47?
705
If w varies directly as 2x-1 and w equals 9 when x equals 2 find x when w equals 15?
The phrase "varies directly as" means that there is a number k such that w = k(2x - 1). From the results given for w = 9 when x = 2, 9 = k(4 - 1), or k = 3. Then when w is 15, 15 = 3(2x - 1), or 15 = 6x - 3, or 6x = 15 + 3, or x = 18/6 = 3.
If y varies directly as x and y equals fifteen and when x equals 6 find y when x equals 10?
y = x/k so 15 = 6/k making k = 0.4. when x = 10 y = 10/0.4 ie 25 alternatively y/x = k ie 15/6 = k so k = 2.5; y/10 = 2.5 making y = 25.
If X varies inversely as Y and X equals -24 when Y equals 15 find X when Y equals -36?
xy = is a constant (k) so k = -360. When y = - 36, x = 10
What times 2 equals 34?
17
K divided by 2 - k divided by 5- k divided by6 equals 2?
k/2 -k/5 -k/6 = 2 Multply all terms by 30: 15k -6k -5k = 60 4k = 60 k = 15
K j equals j but how is that?
K j equals j when K is 1 or j is 0.
How would you evaluate 15k when k equals 3?
Therefore 15k is 15 times 3 = 45
Solve the equation k plus 3.4 equals 9?
k equals 5.6
If it is that 546 k equals 273°, then it follows that 400 k equals?
1200°
P varies jointly as q r and s One set of values is p equals 70 q equals 7 r equals 5 and s equals 4 Find p when q equals 2 r equals 15 and s equals 7?
If P varies jointly as q, r and s - assume this is in direct proportion, then P ∝ qrs so P = kqrs where k is a constant.70 = k x 7 x 5 x 4 = 140k : k = 140/70 = 0.5When q = 2, r = 15 and s = 7 then,P = 0.5 x 2 x 15 x 7 = 105
