Zach time of reading every weekend forms a sequence with these terms: 10, 20, 40, 80. On the other hand, that of Victoria forms a sequence with terms: 35, 50, 65, 80. By keenly observing the sequences, Zach's sequence is a geometric sequence with a common ratio equal to 2 and Victoria's sequence is an arithmetic or linear sequence with a common difference of 15. Thus, the answer is letter B.
So the question ask to determine how long that the wooden artifact found in an ancient tombs and contains 70% of the carbon-14 was made, and base on the fact and the given data about the said artifact, the possible answer would be that the the artifact is 2948 years old. I hope you are satisfied with my answer
25 ÷ (6 - 1) = 25 ÷ 5 = 5, she saved 5 nickels,
5 nickels = 5 × 5 = 25 cents = $0.25
5 + 25 = 30, she saved 30 dimes, 30 dimes = 300 cents = 3 dollars.
3 + 0.25 = $3.25, she saved $3.25 in all.
Hello!
3 inches equals 90 miles
We have to find what multiplied by 3 is 1/2
we can do 3 / 1/2 to find this
3 / 0.5 = 6
So they divide it by 6
We do 90/6
90/6 = 15
The answer is 15
Hope this helps!
-4d + 2(3+d)= -14
distribute the 2(3+d)
-4d + 6+ 2d= -14
Combine the like terms
-4d + 2d + 6= -14
-2d + 6 = -14
subtract 6 to -14
-2d = -20
divide by -2
d= -20/-2
d= 10
Check your answer
-4(10) + 2(3+ 10) = -14
-40 + 6 + 20
-40 + 26= -14
