So x + y = 45, and 4x + 5y = 195. Get y by itself. Subtract x from both sides in the first equation to get y = 45 -x, and subtract 4x from the second equation to get 5y = 195 - 4x. Divide by 5 to both sides to get y = 39 - 4/5x. 39 - 4/5x = 45 - x. Add x to both sides to get 39 - 1/5x = 45. Subtract 39 from both sides to get -1/5x = 6. Divide by -1/5 to get x = -30, or 30. In the first equation, do 30 + y = 45. Subtract 30 from both sides to get y = 15. Check. 4(30) + 15(5) = 195, or 120 + 75 = 195.
What do you mean? Which relation is a function do you mean fraction and if yes then where are the options.
Answer:
y=-1x+1
Step-by-step explanation:
Given:U.S Flag - rectangle in shapescale of 0.5 cm = 1 inlength of the scale 2.5 cmwidth of the scale 4.75 cmperimeter of the scale = 2(L+W) = 2(2.5+4.75) = 2(7.25) = 14.5cmperimeter of the actual flag is:14.5cm * 1in/0.5cm = 29 inches.
