Answer:
3−y
2. 8
4.2bh
Step-by-step explanation:
5(2x+y)=15
2 Divide both sides by 55.
2x+y=\frac{15}{5}2x+y=
5
15
3 Simplify \frac{15}{5}
5
15
to 33.
2x+y=32x+y=3
4 Subtract yy from both sides.
2x=3-y2x=3−y
5 Divide both sides by 22.
x=\frac{3-y}{2}x=
2
1. 3−y
2. 8
2.Add 2y2y to both sides.
x=-8+2yx=−8+2y
2 Regroup terms.
x=2y-8x=2y−8
Answer:

Step-by-step explanation:
This sentence isn't always true.
- here is a counter example :
The trick is to use fractional numbers .
let's analyse this example :
1/2=0.5 and 1/4=0.25 but 1/8=0.125
0.125<0.25<0.5
- here is another example : (1/2)*(1/3)=1/6
- the same thing : 1/6<1/3<1/2
The most improbable simulation for this coin is the heading when a coin is tossed 20 times will be 15.
<h3>What is probability?</h3>
Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
A coin is biased to display heads 75% of the time.
It is tossed 20 times, and the outcomes are recorded.
Then the probability of getting heads when a coin is tossed 20 times. Then we have

Answer:

Step-by -step explanation:
Solving inequalities is similar to solving equations.

Subtract 10 from both sides.

Divide by 5 from both sides to isolate the x.
