Answer:
Step-by-step explanation:
Because of the right angle (90 deg) in red, and the horizontal line on the bottom axis,
we know that :
49 + (1+5x) = 90
solving for x delivers x=8
The answer 0.14 is equivalent to 140%. You can check this answer by moving the decimal 3 places to the right.
1) 96 * 6 2/3%= 6.4
2) 750 * 33 1/3%= 250
3) 240 * 66 1/2%= 159.6
Hope this helps! :)
