K - 20 equals 2k - 13?
k=-7
How do you solve 7 9 plus k equals 84?
79 + k = 84 84 - 79 = k k = 5
What is the answer to 4k-3 equals 3k plus 4?
Take 3k from both sides to get k-3 equals 4, so k is 7
What does 7 equals S a S mean?
7 = Swans a-swimming
What is 13 equals 7 plus s?
13 = 7 + s(13 - 7) = (7-7) + s6 = s
R varies directly as s find r when s equals 7 and k equals 5?
Since r varies directly with s, we have r = ks (replace k with 5 and s with 7) r = (5)(7) r = 35
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
What is 35 divided by k equals 5?
7
K - 20 equals 2k - 13?
k=-7
What is 4k-7 equals 7?
4k-7 = 7 4k = 14 k = 3.5 or k = 7/2
Find an equation of joint variation if 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?
If P varies directly with q, r and s then P = kqrs, where k is a constant. As 70 = k x 7 x 5 x 4 = 140k : k = 70/140 = 1/2 The equation of joint variation is P = ½qrs.
K times 7 equals 35?
5
If z - 7 - 2 equals 2 then z equals -3 and z equals -11?
2+2+7=11 K?
How do you solve 7 9 plus k equals 84?
79 + k = 84 84 - 79 = k k = 5
What is the smallest integer k such that r3 equals s2 equals k where are and s are positive integers?
If 'r' and 's' can be the same integer, then (1)3 = (1)2 , and k = 1 .If 'r' and 's' must be different integers, then (4)3 = (8)2 , and k = 64 .
How do you write it in numbers k is a function of n and 7 times n equals k?
k = f(n) = 7n
What is the answer to 4k-3 equals 3k plus 4?
Take 3k from both sides to get k-3 equals 4, so k is 7
