We can solve this question easiest by putting it as 2 equations.
First, well put the original equation, 2c+5b=55,000. B stands for the cost of backyard pool weddings and c stands for the cost of carribean weddings.
We got this equation because the question states that there were 2 carribean weddings and 5 pool weddings, and the amount of money obtained was $55,000 total as a result.
Now, we’ll put the extra information into an equation, c-10,000=b. We got this equation because it clearly states that backyard pool weddings cost 10,000 less than Caribbean, so c-10,000=b.
Now, we have to solve. Since the first equation has 2 variables, it is unsolvable. This is where the second equation comes in. We can rewrite c-10,000=b as b+10,000=c.
Now, since b+10,000=c, substitute b+10,000 for c in the first equation.
The result is 2(b+10,000)+5b=55,000.
Now that we only have one variable in the equation, it is solvable.
20,000+7b=55,000
7b=55,000
B=7,857
Now to solve for c, insert 7,857 for b in the second equation.
7,857+10,000=c
17,857=c
The cost of carribean weddings was $17,857.
The cost of a backyard pool wedding was $7,857.
Hope this helps!
So the problem wants to compute what could David should score in the fourth math test to ensure an average score of at least 90. So base on the score the possible total of the four score must be 360 to make their average of minimum of 90 so the answer would be letter B. X>93
The explicit formula for given geometric sequence is:
Step-by-step explanation:
Given geometric sequence is:
6,30,150,750....
First of all we will find the common ratio.
Common ratio is the ratio between two consecutive terms of a geometric sequence
In the given sequence
a1 = 6
a2 = 30
a3 = 150
a4 = 750
Now
The explicit formula for geometric sequence is:
