Solve for x over the real numbers:
x^2 - 10 x - 27 = 0
Hint: | Solve the quadratic equation by completing the square.
Add 27 to both sides:
x^2 - 10 x = 27
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 25 to both sides:
x^2 - 10 x + 25 = 52
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x - 5)^2 = 52
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x - 5 = 2 sqrt(13) or x - 5 = -2 sqrt(13)
Hint: | Look at the first equation: Solve for x.
Add 5 to both sides:
x = 5 + 2 sqrt(13) or x - 5 = -2 sqrt(13)
Hint: | Look at the second equation: Solve for x.
Add 5 to both sides:
Answer:
x = 5 + 2√(13) or x = 5 - 2√(13)

Maria is making paper flowers as decorations for the fall dance. She has made 40 flowers so far, and she is 16% finished. If she plans to finish making 70% of the total flowers needed by tonight, how many more will she need by then? Please answer soon its due 11:59 tonight!!
Answer:
the number of additional she needed is 135
Step-by-step explanation:
The computation is shown below:
GIven that
40 flowers of 16%
So for 100% it would be
= 40 ×100 ÷ 16
= 250
Now she needs to make is
= 70% - 16%
= 54%
Now the additional would be
= 250 × 54%
= 135
Hence, the number of additional she needed is 135

Billy and Tom are out to dinner. Their bill comes to a total of $100. They have a 15% off coupon but tax and tip must also be included. The tax is 6% and is applied before the 20% tip. If Billy and Tom want to split the bill, how much will they each have to pay?
1. How much is their bill after the coupon has been applied?
2. With the coupon applied, what is their new total (including the tax)?
3. With their new total, Billy and Tom can now determine the tip for their server. What is the final total, including the tip?
4. What will Billy and Tom each have to pay to split the bill evenly?
Please answer labeled with numbers! thankyou!
Answer:
1. $85
2. $90.10
3.$108.12
4.$54.06
Step-by-step explanation:
100-15=85 (15% of 100 is 15)
6 percent of 85 is 5.10. So 85 + 5.10=90.10
20 percent of 90.10 is 18.02. So add that to the total. 90.10+18.02=108.12
Now divide by 2 to get how much they each will pay 108.12/2 = 54.06
Solve the equation below for x.
0.5(x + 7) + 9 = 43
Answer:
x = 61
Step-by-step explanation:
0.5(x + 7) + 9 = 43
0.5x + 3.5 + 9.0 = 43
0.5x + 12.5 = 43.0
0.5x = 30.5
x = 30.5 / 0.5
x = 61
The solution to the value of x in the equation is 61
In a mathematical concept, an algebraic expression consists of variables, constants with their arithmetic operations.
From the given parameters
0.5(x + 7) + 9 = 43
Open brackets
0.5x + 3.5 + 9 = 43
0.5x + 12.5 = 43
0.5x = 43 - 12.5
0.5x = 30.5
x = 30.5/0.5
x = 61

Write the equation that represents the situation then determine the cost of 5 cans of coffee: A supermarket sells 2 cans of ground coffee for$18.50. The cost of coffee varies directly with the number of cans.
Answer:
The equation is;
C = kg
c is the cost in $
k is the proportionality constant $/can
g is the number of cans
cost of 5 cans of coffee is $46.25
Step-by-step explanation:
From the question, 2 cans of ground coffee costs $18.50
Let c be the cost and g be the number of ground coffee
18.50 = k * 2
where k is the constant of proportionality;
k = 18.5/2
k = 9.25
So, the cost of 5 coffee cans will be;
c = 9.25 * 5 = $46.25
Is this correct?
