The answer is C.......Sports Stamps = 4 , Holiday Stamps = 2 , Presidents Stamps = 8. He said 4 times as many presidents than holiday. So the number of presidents stamps is the product of the holiday stamps times 4. 4 times 2 is 8. Add them all together
Answer:
<h2>
</h2>
Step-by-step explanation:
-4÷2 = -2
8÷(-4) = -2
-16÷8 = -2
So this is a geometric sequence with the first term of 2 and a common ratio of -2
the nth term of a geometric sequence:
Therefore:
Answer:
Hello! The number equals 4.
Step-by-step explanation:
Here is the equation:
2N - 4 < 3N.
2 * 4 - 4 < 3 * 4.
8 - 4 < 3 * 4.
8 - 4 < 12.
4 < 12.
The number on the left is less than 3 times itself on the right.

Answer:
At 53 mph, he traveled for 1.5 hours
At 58 mph, he traveled for 2 hours
Step-by-step explanation:
Mathematically;
distance = speed * time
let the time for the first part of the trip be x hours and the second part be y hours
Total hours is 3.5
So therefore;
x + y = 3.5 ••••••••(i)
Now let’s work with the rate
53 mph for x hours = 53 * x = 53x miles
58 mph for y hours = 58 * y = 58y miles
Adding both;
53x + 58y = 195.5 miles ••••••••(ii)
We have two equations to solve simultaneously
From i, x = 3.5 - y
insert into ii
53(3.5-y) + 58y = 195.5
185.5 - 53y + 58y = 195.5
5y = 195.5-185.5
5y = 10
y = 10/5
y = 2 hours
x = 3.5 - y
x = 3.5 - 2
x = 1.5 hours
