Answer:
C
Step-by-step explanation:
Solve for each choice until you get the answer 1/5.
A.
2 - 4/5
10/5 - 4/5 = 6/5; this is not 1/5
B
8 - 8/5
40/5 - 8/5 = 32/5; this is not 1/5
C
3 - 16/5
15/5 - 16/5 = -1/5
5 - 26/5
25/5 - 26/5 = -1/5
7 - 36/5
35/5 - 36/5 = -1/5; although this is negative, it still has the same proportionality of 1/5
Answer:
B. The student did not properly apply the addition property to isolate x
Explanation:
When given an equation to solve, always remember that when you do an external operation (add/subtract/multiply a term or divide by a term) on one side of the equation, the same operation should be applied on the other side in order to maintain the equality of the equation.
Now, let's take a look on the steps done:
Step 1:
3 = 2 - x
Step 2:
3 = 2 - 2 - x
Step 3:
3 = -x
Now, note n step 2, the student wanted to get rid of the 2 next to the x, therefore, he subtracted 2. However, the student did not subtract the 2 from the other side of the equation. Since we're taking addition (we're adding a -2), therefore, the student incorrectly applied the addition property to isolate the x.
The correct steps would be as follows:
Step 1:
3 = 2 - x
Step 2:
3 - 2 = 2 - 2 - x
Step 3:
1 = - x
Hope this helps :)

Every time you draw, its minus one from denominator
1st marble red: 5/8
2nd marble green: 3/7
Answer:
1/4
Step-by-step explanation:
Simplify the following:
(1/6)/(2/3)
Multiply the numerator by the reciprocal of the denominator, (1/6)/(2/3) = 1/6×3/2:
3/(6×2)
3/6 = 3/(3×2) = 1/2:
1/(2×2)
2×2 = 4:

All of these answers are wrong? The sum of 8 and twice a number would be 8 + 2n. If it was twice the sum of 8 and a number it would be D. None of them are correct but D is technicllay the closest?
