We are adding 7 each time.
The formula for an arithmetic sequence is
first term+(n-1)d
Where n is the number of terms, and d is the common difference
In this case, n is 35 and d is 7
Plug the numbers into the formula and you get
-33+(35-1)7
Solve
-33+(238)= 205
Answer:
12 7/8
Step-by-step explanation:
18 3/4 = 75/4
5 7/8 = 47/8
2(75/4) = 150/8
150-47 = 103
103/8 = 12 7/8
Answer:
2.9661582
Step-by-step explanation:
<span>The answer is c. 1.5r + 2.5(5 – r) = 10.50. Let r be the number of raisins and p be the number of peanuts. Raisins cost $1.50 per pound: 1.5r. Peanuts cost $2.50 per pound: 2.5p. Jeremy spends $10.50: 1.50r + 2.50p = 10.50. Jeremy makes 5 pounds of trail mix: r + p = 5. So, we have the system of two equations: 1.5r + 2.5p = 10.50 and r + p = 5. Use the second equation to express p: p = 5 - r. Now, substitute p in the first equation: 1.5r + 2.5(5 - r) = 10.50. Therefore, the correct choice is c. 1.5r + 2.5(5 – r) = 10.50.</span>
The probability of both balls being blue is 8/10. Why? Because if you add the number of green balls out of both urns, which you add together, will give you your denominator, then you add the number of blue balls from each bag and get the total, that will be the numerator. So,everything will equal out to 8/10.
