We have to calculate the percent decrease in temperature and to choose the correct answer. We can solve the proportion: 320 / 280 = 100 / x; then we will cross multiply. 320 x = 280 * 100; 320 x = 28,000; x = 28,000 : 320 ; x = 87.5 %. Finally : 100% - 87.5 % = 12.5 %. Answer: The percent decrease is C. <span>12.5 %.</span>
Answer:
a 90° clockwise rotation about the origin and then a reflection a cross the x-axis
the value of 3x +2y if x=5 and y=4 is 23
<span>9x+5=4(x+2)+5x
Then distribute on the right side
9x+5=4x+8+5x
Then simplfy
9x+5=9x+8
Then subtract 9x from both sides
5=8
5 is not equal to 8 so, no answer.
