An equation?
It is not possible to solve a single linear equation in two unknown variables (b and t).
19-2t = 7 -2t = 7-19 -2t = -12 t = 6
Rearranging the the equation to make c the subject:- c = kVp-2t
t = 28
3s=2t can also be written as 3y=2x or 3x=2y. Either way, it is linear. To find out if it is linear, simply graph it. If you can draw a completely vertical line through any point of the graph without intersecting more than one point of the graph, then it is linear. This equation (3s=2t), it is linear.
An equation?
It is not possible to solve a single linear equation in two unknown variables (b and t).
19-2t = 7 -2t = 7-19 -2t = -12 t = 6
-2t = -10
3t + 7 = 2t - 5 3t = 2t - 12 t = -12
Rearranging the the equation to make c the subject:- c = kVp-2t
3tan (2t) = sqrt(3) tan (2t) = sqrt(3)/3 = 0.577 from tangent tables, 2t = 30 degrees t = 15 degrees
2t
2t-3-3 = 7 2t = 7+6 2t = 13 t = 6.5
In 2t+8 19
Heyy, For this question, we first need to add 2t to both sides of the equation to get: 75 + 4t = 100 Now, subtract 75 from both sides of the equation to get: 4t = 25 At this time, divide both sides by 4 to get t alone and get: t = 25 / 4 OR 6.25 FINAL ANSWER = t=6.25
