Figure #22. What Is X? 58C 122990B48D21842

Answers

Answer 1
the answer is 58.

the inside of a triangle adds to 180, so by subtracting the inner corner numbers already known (80&42) you’re left with 58

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)

Solve the equation below for x.
0.5(x + 7) + 9 = 43

Answers

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

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!!

Answers

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

A 7-pack of tickets to the zoo costs $78.61. What is the unit price?

Answers

Answer:

$11.23

Step-by-step explanation:

To find the unit price divide the price by the product. For example, 12 ounces of juice costs $2.45. You divide $2.45 by 12 ounces. The unit price would be $0.20.

I hope this helped you, if it did more than all the other answers that may be on your question, feel free to give me brainliest, I would really appreciate it.

A 7-pack of tickets to the zoo costs $78.61. Therefore, the unit price of ticket to the zoo $11.23.

What is division?

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into same number of parts.

Given that a 7-pack of tickets to the zoo costs $78.61.

To find the unit price;

Cost of one pack of ticket to the zoo = total cost of 7 pack of tickets / number of tickets

Cost of one pack of ticket to the zoo = $78.61 / 7

Cost of one pack of ticket to the zoo = $11.23

Therefore, the unit price of ticket to the zoo $11.23.

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.

Answers

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

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?

Please answer labeled with numbers! thankyou!

Answers

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
