2j = .5k
Let j = 5
2(5) = .5k
10 = .5k
divide both sides by .5
20 = k
When j = 5 , k = 20
Answer: B. 1/x^4
When you divide the coefficients of exponents you must subtract the exponents. In this cause it got to x^-4. You cannot leave it as a negative exponent so you must put it as the denominator in this cause to get rid of the exponent making the answer b. 1/x^4.
Three. For these questions, ignore the positive or negative sign.
Answer:
1/10
Step-by-step explanation:
The probability of flipping heads is 1 out of 2 or 1/2
The probability of getting a 5 on the spinner is 1/5
The probability of getting both is 1/2 * 1/5 = 1/10
You should try this out by listing all the ways this can happen.
