Answer:
The sum of all the sides to this quadrilateral will equal a total of 20 inches, so you set up the equation:
2 + 2x + 7 + x + 2 = 20
Solve for x by combining like terms;
(2 + 7 + 2) + (2x + x) = 20
Which simplifies to;
11 + 3x = 20
Get rid of constants;
-11 -11
3x = 9
Isolate x by getting rid of it's coefficient;
/3 /3
<u>x = 3</u>
Now, to find the length of PQ, we plug in the value of x(3) into the equation that contains the line PQ.
x + 2
<u>3</u> + 2
= <u>5 inches.</u>
Now, to find the length of RS, we plug in the value of x(3) into the equation that contains the line RS.
2x
2(3)
= <u>6 inches.</u>
It's the last one!
Hope this helps!
Answer:
The answer is 0.4
Step-by-step explanation:
Since we do multiplication first, we do 0.2*0.5. That equals 0.1.
Next, we do addition. 0.3+0.1 is 0.4.
If you are finding the sample space see if it is biased or not. and if it population then find the experimental or theoretical.
