Answer:
- x = 81 and 3/4
Step-by-step explanation:
8 × 2 – 4x = 363
16 - 4x = 363
Subtract 16 from each side:
16 - 16 - 4x = 363 - 16
- 4x = 327
Divide each side by 4:
- 4x ÷ 4 = 327 ÷ 4
- x = 81 and 3/4
The answer would be 140° or D because supplementary means the angles add up to 180°. Therefore, 180°-40°=140°
<span>You would have to wait 318 years for 1/5 (20%) of the Radium to disappear. 1590 is the point where half of the Radium would decay, so if you take 20% of that, it would equate out to 318 years. Radium has a long half life!</span>
<span>Yes, but with the following two rules to remember. If you multiply or divide both sides by a negative number, then the inequality sign is reversed (> becomes ). Adding and subtracting numbers have no effect on the direction of the inequality. [ Also, if you have a 'not equals' sign, then it is unaffected by the multiplication. The same is true if you take the reciprocal of both sides. Example: with the equation: 1/x = 2, take the reciprocal and x = 1/2. With the inequality 1/x 1/2. You could also solve it by multiplying both sides by x, then dividing both sides by 2, and get 2 2. Another example: 3 - x > 7. Subtract 3 from both sides: -x > 4. Multiply both sides by -1: x 7 + x, then subtract 7 from both sides: -4 > x, which means the same as x < -4</span>
