Answer:
Step 3.
Operation error, where the sign on the number changes from -ve to +ve where shifted to the left side of the equation.
Step-by-step explanation:
Given that 2(10 - 13x) + 9x = -34x + 60
<u>Step 1. Distribute</u>
20-26x+9x=-34x+60
<u>Step 2: Combine like Terms</u>
20-17x=-34x+60 -------------------------(-26x+9x = -17x)
<u>Step 3: subtraction property of equality</u>
-17x+34x=60-20--------------------- (60-20 =40)
-17x+34x=40
<u>Step 4 :Addition property of Equality</u>
-17x+34x=40-------------------(-17x+34x =17x)
17x=40
<u>Step 5: Division property of Equality</u>
17x=40
17x/17 = 40/17
x=40/17
Answer
x=40/17
<u>Errors</u>
In step 3
-17x+34x = 17 x and not 51x
In step 5
-51x=40
x=-40/51 (not the other way round, -51/40) however correct operation is supposed to be;
17x=40, hence x =40/17
2j = .5k
Let j = 5
2(5) = .5k
10 = .5k
divide both sides by .5
20 = k
When j = 5 , k = 20
Base angle theorem proves that
Answer: 
Step-by-step explanation:
In order to find the value of "x", it is important to remember that:
We can identify in the figure that:
Then:
Solving for AB:
Now, since there are 360° in a circle, we know that:
Then we can substitute 
into 
and solve for "x". This is:
Answer:
Both point are y=0. The difference between the two is that 2/3 is always decressing and 3/2 is always incressing.
Step-by-step explanation:
