k equals 5.6
k = 129
k = pv/t. It is not possible to solve further with the information available.
79 + k = 84 84 - 79 = k k = 5
a = F divided by km
To do this, simply solve the multiplication problem:5.4 x 6.007 = k32.4378 = k
X2 = k Take square root each side. X = (+/-) sqrt(k) ============
We cannot answer since you didn't give any numbers at all to solve this with.
