Answer:
<u>4</u>
Step-by-step explanation:
First you would need to look at the line at the right. It has 2 parts, 3 and 2. When added you get 5.
As when you look at the other side it only has 2 and x.
To make it simple 5 - 1 = 4.
That is your final answer.
Hope this helps!
Answer:
3900
Step-by-step explanation:
We want the sum from 5 to 195
5, 10, 15, 20,......195
an = 5 + 5(n-1) since we can write this as an arithmetic sequence, adding 5 each time
The sum of the terms of an arithmetic sequence is given by
Sn = n/2 [2a1 + (n - 1)d],
where d is the common difference of 5 and n is the term we want to add to
195/5 = 39 so it is the 39th term
s39 =39/2 [2*5 + (39-1)*5)]
s38 = 19.5[10+38*5]
=19.5*[10+190]
19.5*200
=3900
Answer:

Step-by-step explanation:
Given Equations:
Equation:1
Equation:2

Dividing by '2' both sides:

The values are:

Answer:
5 and 12
Step-by-step explanation:
Adding 5 + 12 gives you 17, and multiplying 5 × 12 will give you a product of 60
