Answer:

x > -3.

Step-by-step explanation:

The circle on the -3 is clear. That means that -3 is not included in the inequality.  The shading is to the right so the answer is x > -3 ( x is greater than -3).

Answer:

x > -3

the third option

Step-by-step explanation:

5. Solve each equation by systematic trial.
Basile [38]

Answer:

a) x = 260

b) g = 218

c) z = 30

d) h = 5

Step-by-step explanation:

a) x-68=192

Predict a number; let's say x = 225

225-68=192\\157=192

Too low; try with a higher number; let's say x = 270

270-68=192\\202=192

Too high, we're closer.

x = 260

260-68=192\\192=192

--------------------------------------------------------------------------------------

b) g+33=251

let's say g = 230

230+33=251\\263=251

Too high. Try g = 221

221+33=251\\254=251

We're almost there. Let's try with g = 218

218+33=251\\251=251

----------------------------------------------------------------------------------------

c) 3z-16=74

Let's try with z = 15

3(15)-16=74\\45-16=74\\29=74

Too low; try a higher number. z = 30

3(30)-16=74\\90-16=74\\74=74

--------------------------------------------------------------------------------------------

d) 15h+9=84

Let's try with h = 6

15(6)+9=84\\90+9=84\\99=84

Too high; let's try with h = 5

15(5)+9=84\\75+9=84\\84=84

A doctor can prescribe one of two drugs to treat a certain disease. Drug A will cure 75% of the cases but has unwanted side effe
Phoenix [80]

The total number of patients experienced unwanted side effects is 48

<u><em>Explanation</em></u>

60 patients are given drug A and drug A has unwanted side effects in 40% of the cases.

So, the number of patients experienced side effects for drug A = 40% of 60 =(0.40*60)= 24

Now 80 patients are given drug B and it has side effects in 30% of the cases.

So, the number of patients experienced side effects for drug B = 30% of 80 =(0.30*80)= 24

So, the total number of patients experienced unwanted side effects = 24+24 =48
