Solve to find the value of x. 40-x/3 = 4+x

Answers

Answer 1

Answer: $(40-x)/(3) = 4 + x \n \n 40 - x = 12 + 3x \n \n 40 = 12 + 3x + x \n \n 40 = 12 + 4x \n \n 40 - 12 = 4x \n \n 28 = 4x \n \n (28)/(4) = x \n \n 7 = x \n \n x = 7 \n \n Answer: \fbox {x = 7}$

Answer 2

Answer: $(40-x)/(3) = 4 + x\n\n40 - x = 3(4 + x)\n\n40 - x = 12 + 3x\n\n40 = 12 + 4x\n\n4x = 28\n\n\boxed{\bf{x=7}}$

then you add 150 to 300 which means that the shop sells the skis for 450 dollars.

The endpoint of MP are M(2,1) and P(14,10). If point K partitions MP in aratio of MK:KP=3:2, what are the coordinates of K?

Answers

Answer: The required co-ordinates of he point K are (9.2, 7).

Step-by-step explanation: Given that the the endpoint of MP are M(2,1) and P(14,10) and the point K partitions MP in the ratio of MK : KP = 3 : 2.

We are to find the co-ordinates of point K.

We know that

the co-ordinates of a point that divides the line joining the points (a, b) and (c, d) in the ratio m : n are given by

$\left((mc+na)/(m+n),(md+nb)/(2)\right).$
