3r-5s= -4 5r+3s= 16 Multiply the 1st equation by 5 and the second by 3... 15r-25s= -20 15r+9s=48 Subtract both -34s= -68 divide by -34 s=2 substitute 3r-10= -4 3r=6 r=2

math
Find a value of n when the sq. root of n^2 is NOT n.

Math
Change it into to inches. So 5= 60 7 and 8" is= 92 and 19= 228. 60/92 = x/228. SOlve the proportion to get x is about = to 149. Divide by 12 and you get about 12 feet tall.

algebra
another way to put this is 1/3 * by 8/3. this is 8/6 or 4/3.

A track meet awards 6, 5, 4, 3, 2 and 1 points for 1st, 2nd, 3rd, 4th, 5th and 6th places, respectively. Team A’s only two runners originally earned 6 points in the first race with both runners finishing in the top 6, but then the winner of the first rac...

Math
The surface area of a particular cube is 600 square inches. When the edges of the cube are doubled in length, what is the volume of the new cube, in cubic inches?

Math
first turn this into a triangle... the base is 66 and you know two of the angles (30 deg. and 90 deg (the base and the ground)). Now this is a 30-60-90 triangle. the rules 4 30-60-90 is the base is x, the hyp. is 2x and the other leg is x multiplied by the sq. root of 3. you k...

Math
h= 66 root 3 or 66 multiplied by the sq. root of 3.
