Answer:
k = 4
Step-by-step explanation:
-9 +8k = 7+4k
Subtract 4k from each side
-9 + 4k = 7
Add 9 to each side
4k = 16
Divide by 4
k = 4
Plug in the value you got for k:
-9 + 8(4) ? 7 + 4(4)
-9 + 32 ? 7 + 16
23 ? 23
23 = 23
Im Not Sure But Im Thinking 7/10 Wrote As in A Fraction .
Since you want to put this in simplest form ... the easiest way you can do it is
3 (100) + 97
So, step 1] 3(100)= 300
Step 2] 300 + 97 = 397
Answer : 397 over 100

There's other ways too, but it'll take me all night to finish it
For this case we have a factored expression, of a second degree equation:
(
To find the solutions:
we add 3 to both sides of the equation:

We subtract 8 on both sides of the equation:

Thus, the solutions of the equation are:

Answer:

Answer:
When we write numbers in scientific notation, we must put the first non-zero digit ahead of the decimal. In this case, the decimal would be behind the 3. Because we moved the decimal places four times to the right, our exponent will be 4. Thus,
3.00 x 10⁻⁴
