Answer:

3x = -2 2/5 or -2.4

Step-by-step explanation:

5x + 8 = 4

5x = 4 - 8

5x = -4

x = -4/5

3x = y  If x = -4/5

3 * -4/5 = y

-12/5 = y

-2 2/5 = y

Please need help fast. Look at the picture.<br><br> Please explain.
Zigmanuir [339]
The answer is 17

This is because 1 + 2 must equal 180 as they are in a straight line.
So 4x + 2 + 110 = 180
Take away 110 from both sides
4x + 2 = 70
Take away 2 from both sides to get 4x = 68. Finally, divide both sides by 4 to get x = 17

KiRa [710]

Answer:

The answer is 9/11.

Step-by-step explanation:

To find the answer you'd first add up how many patients you have:

80+10+20 = 110.

Now find out that how many patients are taking a real drug, which is represented by 80+10 = 90.

So, the probability of a patient NOT getting a placebo is 90/110

Simplified would be 9/11

Thus the answer is 9/11....
