1st one x=245°

2nd one x= 250

Step-by-step explanation:

hope its correct

hope u find it helpful

Answer:

x = 245 and x = 20

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5 , then

sum = 180° × 3 = 540°

Sum the interior angles and equate to 540

25 + 112 + 100 + 58 + x = 540

295 + x = 540 ( subtract 295 from both sides )

x = 245

---------------------------------------------------------------

5x + 2 + 3x + 5 + 8x + 8 + 4x + 15 + 5x + 10 = 540

25x + 40 = 540 ( subtract 40 from both sides )

25x = 500 ( divide both sides by 25 )

x = 20

Answer:

a. [tex]5 + (-3x) = -4[/tex]

b. [tex]5 + (-3x) = 4[/tex]

c. [tex]5 + (-3x) = 14[/tex]

Step-by-step explanation:

Given

[tex]5 + (-3x)[/tex]

Required

Evaluate

(a) x = 3

[tex]5 + (-3x) = 5 + (-3*3)[/tex]

[tex]5 + (-3x) = 5 + (-9)[/tex]

Remove bracket

[tex]5 + (-3x) = 5 -9[/tex]

[tex]5 + (-3x) = -4[/tex]

(b) x = 1/3

[tex]5 + (-3x) = 5 + (-3*1/3)[/tex]

[tex]5 + (-3x) = 5 + (-1)[/tex]

Remove bracket

[tex]5 + (-3x) = 5 -1[/tex]

[tex]5 + (-3x) = 4[/tex]

(c) x = -3

[tex]5 + (-3x) = 5 + (-3*-3)[/tex]

[tex]5 + (-3x) = 5 + (9)[/tex]

[tex]5 + (-3x) = 14[/tex]

Answer:

2:12 or 1:6

Step-by-step explanation:

there are 12 students. you and your friend are 2 of the 12. so it would be a 2:12 chance that you or your friend would get picked. unless if you simplify which then it would be a 1:6 chance that either of you would get picked.

The retail price of the skateboard = [tex] \color{hotpink}\boxed{\bold{\tt\bold{\$110}}}[/tex]

Given :

▪︎Cost price of a skateboard in a sports shop = $80

▪︎Percentage of markup in the price of the skateboard = 37.5%

Which means :

The retail price of the skateboard :

= Intial price of skateboard + 37.5% of it's initial price

[tex] = \tt80 + 37.5\% \: of \: 80[/tex]

[tex] =\tt 80 + \frac{37.5}{100} \times 80[/tex]

[tex] =\tt 80 + \frac{37.5 \times 80}{100} [/tex]

[tex] = \tt80 + \frac{3000}{100} [/tex]

[tex] =\tt 80 + 30[/tex]

[tex]\color{plum} = \tt\bold{\$110}[/tex]

Therefore, the retail price of the skateboard = $110

Answer:

65 square units

Step-by-step explanation:

The area of a triangle is: height times base divided by two.

So the area of one of the triangles is 10 square units.

multiply this times 4 to get the total area of the triangles

then add the area of the square which is 5 times 5

25 plus 40 = 65 square units

Answer:

Step-by-step explanation:

Answer:

The quadratic equations and their solutions are;

9 ± √33 /4 = 2x² - 9x + 6.

4 ± √6 /2 = 2x² - 8x + 5.

9 ± √89 /4 = 2x² - 9x - 1.

4 ± √22 /2 = 2x² - 8x - 3.

Explanation:

Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.

We have to solve all of the five equations to be able to match the equations with their solutions.

2x² - 8x + 5, here a = 2, b = -8, c = 5.                                                  x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4.     24 can also be written as 4 × 6 and √4 = 2. So                                                                                     x = 8 ± 2√6 / 2×2= 4±√6/2.

2x² - 10x + 3, here a = 2, b = -10, c = 3.                                                   x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So                                                                              x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.

2x² - 8x - 3, here a = 2, b = -8, c = -3.                                                    x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4.     88 can also be written as 4 × 22 and √4 = 2. So                                                                             x = 8 ± 2√22 / 2×2 = 4± √22/2.

2x² - 9x - 1, here a = 2, b = -9, c = -1.                                                     x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4.                                          x = 9 ± √89 / 4.

2x² - 9x + 6, here a = 2, b = -9, c = 6.                                                    x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4.                                                                             x = 9 ± √33 / 4 .
