since the original price was ninety we have to multiply 5/6 by 90
90/1(5/6)
=450/6
=75
You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.
Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.
2(4) + 4k - 9 = (4)(4) - (4) + 1
Then 8 + 4k - 9 = 16 - 4 + 1, or 4k - 1 = 13. Then 4k = 14, and k = 14/4, or (after reduction) k = 7/2
If the parameter k equals 7/2, then x = 4 is a solution to the given equation.
To check this out further, start with the proposed solution x = 5 and find k.
Answer:
Exact: $79.96 Rounded: $80.00
Step-by-step explanation:
25% x 4 = 100%
thus $19.99 x 4 = $79.96. Rounded up to $80.00
Answer:
18
Step-by-step explanation:
Fifth grade has 80 students and sixth grade has 80 students. so if you get 90% of both then you have 72 and 72. Add and divide by 8 and you have the answer of 18 parent volunteers going.
Answer:
The price of the drink is: $4
and the bag of popcorn costed $5.5
Step-by-step explanation:
Let b=the price of each bag of popcorn
Let d=the price of each drink
One bag of popcorn costs $b, so 10 bags of popcorn cost 10b. One drink costs $d, so 6 drinks cost 6d. The total cost 10b+6d equals \$79:
10b+6d=79
Likewise, if 3 bags of popcorn and 5 drinks cost $36.50, then:
3b+5d=36.50
Write System of Equations:
10b+6d=79
3b+5d=36.50
