Answer: 42/13
Step-by-step explanation: Multiply everything by 7 to eliminate the fraction:
k+ 21 - 14k = -21
Isolate the variable:
k - 14k = -21-21
13k= -42
divide the sides by -13.
42/13
Answer:
You do (Keep, Change, Flip)
so you keep 9/4
Then change the division sign to multiplication sign
Finally flip the next fraction (10/3) becomes 3/10
9/4 * 3/10 = (9*3)/(4*10) = 27/40
Answer:
The expression consists of 2 factors, and each factor contains 3 terms.
Answer:
To the right
Step-by-step explanation:
The balance point should be adjusted in the direction of the larger sum. Doing so will make that sum smaller.
___
<em><u>Example</u></em>:
Consider a point at -5 and another at +11. A first estimated balance point at 0 will give a right-sum of 11, and a left-sum of 5. The rule above says we should move the balance point to the right.
If we move it to 3, then the right sum is (11-3) = 8, and the left sum is (3-5) = 8, so both sums are equal and the new balance point estimate is in the right place.
