If we use the last equation:
2 x = 18
x = 18 : 2
x = 9
Then we will put it in another equation:
x - 2 y = 3
9 - 2 y = 3
- 2 y = 3 - 9
- 2 y = -6
y = -9 : ( -3 )
y = 3.
The solution is : D ) ( 9, 3 )
2.5 / 18 = 6.4 / x
cross multiply
(2.5)(x) = (18)(6.4)
2.5x = 115.2
x = 115.2 / 2.5
x = 46.08 inches
Hi love...
The correct answer after solving for d is D=78. That’s a quick answer, but I can give you steps on how to solve.
1. Simplify both sides of the equation
2. Isolate the variable
3. Simplify
Then you’d have the answer!
Please let me know if you need further assistance! Have a jolly evening.

There are 109 terms in given series.
According to the statement
we have given that the sum of series is AP series and
This is 19 20.5 22 23.5 ... 181
And the sum of series is 10,900
Now, we have to find the number of terms in the series.
Then we use the summation formula which is
S = n/2 (a + L)
Substitute the all given values in it like
L = 181
A = 19 and S= 10,900
then
10,900= n/2(19+181)
10,900= n/2(200)
After solve the equation for n
10,900= 100n
n = 10,900 / 100
n = 109
There are 109 terms in given series.
So, There are 109 terms in given series.

Answer:
No Solution
Step-by-step explanation:
8x+15=8x (2 times 4x equals 8x)
15=0 (Move the 8x to the other side)
No Solution (15 can't be equal to 0)
