Answer:

12x= 180

Step-by-step explanation:

The sum of a triangle always adds up to 180 so,

(4x-1)+ (2x-1) +6 = 180

12x=180

x=15

Answer:

The equation you could use is the 3rd solution. You need to add all of the nubers that have an x after it because you can't add a number that doesn't have x and a number that does have x.  So once you add all of those,  you add the 10, and keep the subtrction symbol instead of the addition symbol. And like I said before, all triangles are equal to 180.

Answer:

no solutions

Step-by-step explanation:

12x+15=12x

Subtract 12x from each side

12x-12x+15=12x-12x

15 = 0

This is not a true statement so there are no solutions

Answer:

x=24.2198542

ROUND IF NEEDED

Step-by-step explanation:

We are trying to find the height of the tree or the vertical side

We are given

Since we have a side that is adjacent to that angle and we are trying find backside that us opposite of that angle

we are going to use tangent

[tex] \tan(x) = \frac{opp}{adj} [/tex]

plug 38 in for x or theta, x for opp side and 31 for adjacent side

[tex] \tan(38) = \frac{x}{31} [/tex]

Multiply 31 by both sides to find x

x=24.2198542

ROUND IF NEEDED.

Answer:

Step 3: x² + 6x + 64 = -8 + 64

Step-by-step explanation:

At step 3 add 64 on both sides to complete the square.

so x² + 6x = -8

becomes x² + 6x + 64 = -8 + 64 when 64 is added both sides giving us step 3.

continuing from there, we get

x² + 6x + 64 = 56

we then use a² + 2ab + b² = (a + b)² on the left side to get

(x + 8)² = 56 (solve the equation for x)

by taking the root on both sides

√(x + 8)² = √56

x + 8 = +- 2√14 (separate the equations

x + 8 = 2√14

x + 8 = -2√14

Solving for x

x = 2√14 - 8 or x = -2√14 - 8

no, this is false. 1 is greater than 12/20.

Answer:

No. Its not cause 20/20 is what makes ita whole 1 so if ita 12 than its not equal to 1

Answer:

-1/2

Step-by-step explanation:

hello :

f(x)=(−2)^3 (3)^0 (4)^−2

(−2)^3  = -8

(3)^0 =1

(4)^−2 1/ (4)^2 =1/16

so : f(x) = (-8)×(1)×(1/16) = -8/16 = -1/2

Answer:

2,598,960

Step-by-step explanation:

Answer:

The  2598960 cards can be dealt from a standard deck of 52

cards if 5-card selected.

What is permutation and combination?

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

We have a standard deck of 52 cards.

5 cards selected.

Total combination:

= C(52, 5)

= 2598960

Thus, the  2598960 cards can be dealt from a standard deck of 52

cards if 5-card selected.

Answer and Step-by-step explanation:

So, the format you should choose is the second one.

This is what goes in each box:

[4] (p - [6]) = [12]

The 4 is multiplying the price for 1 of the items (and it is 4 because there are 4 items), the 6 is taking away 6 dollars (because coupons take away money from amount) and 12 is the total amount of money.

Now, we solve for p.

Divide each side by 4.

p - 6 = 3

Now, add 6 to each side.

p = 9.

Each item cost 9 dollars.

Answer: 31112

Step-by-step explanation:

Answer: It's 31,112.

26 letters in the alphabet.

1-20 = 20 numbers.

The probability of getting w = 1/26

The probability of getting 17 = 1/20

The probability of both: 1/26 x 1/20 = 1/520

Answer:

Step-by-step explanation:

Answer:

None of the answers provided are equivalent

Step-by-step explanation:

To solve it would be best to simplify each of the expressions you have listed by combining like terms all the x^2 terms have been bolded, the x terms italicized, and the constant terms are underlined

(4x + 1.2) + (2x ^ 2 - 6x + 5) = 2x ^ 2 - 6x + 6.2

(x ^ 2 - 5x + 13) + (x ^ 2 + 3x - 6) = 2x^2 -2x +7

(4x ^ 2 - 6x + 11) + (2x ^ 2 - 4x + 4) = 6x^2 -10x +15

(5x ^ 2 - 8x + 120) + (- 3x ^ 2 + 10x - 13) = 2x^2 + 2x + 107
