Hope this helps
Answer:
third one
Step-by-step explanation:
the third one should be the answer
step 4 came out becoz of taking the common factor(x+1) and combining x2 and (-16)
Step 5 came out becoz of the theory of (a^2-b^2) = (a+b)(a-b)
ps 16 here is equal to 4^2
Answer: 1/6
Step-by-step explanation:
5/6 + -2/3
5/6 + -4/6
5 + -4/6 = 1/6
Decimal Form: 0.166667
Answer:
x= 95/2 or x=47.5 or 47 1/2
Step-by-step explanation:
3x + 10 = 5(x - 17)
First Step:
multiply and combine the right side (parentheses)
5 times x = 5x 5 times -17 = -85
3x + 10 = 5x -85
Second Step:
Add like terms ----> which is: 3x and 5x -----10 and -85
BUT since you only want one x on one side, you combine x first.
3x + 10 = 5x -85
-5x -5x
-2x + 10 = -85
NOW
Third Step: Add the integers---> 10 and -85
you want to get 10 on the same side as the -85, so you subtract it from BOTH sides.
which brings you:
-2x + 10 = -85
-10 -10
<u> </u>
NOW that we've subtracted -10 from -85 it's technically just adding 85 and 10 then putting a negative sign on it.
so now we have:
-2x = -95
Step Four:
divide -2 from each side to get X alone
<u>-2x</u> = <u>-95</u>
-2 -2
ANSWER:
x=47.5
Answer:
2/3
Step-by-step explanation:
I think it is 2/3 because 20 is the probability and 30 are the users. So basically, it is the probability over the total in this case 30. 20/30=2/3. Hope it helps?
