Answer:

Shown Below

Step-by-step explanation:

Alright so first off we are going to use the little 67 on that corner. We know that it's a supplementary angle, and supplementary angles add up to 180.

180 - 67 = 113.

Inside angles of a triangle all add up to 180. Using that we can create the equation:

(x + 27) + x + 113 = 180

simplify.

2x + 140 = 180

subtract 140 on both sides.

2x = 40

divide both sides by 2

x = 20

substitute x into the asked equation.

(20 + 27) = 47

47 is your answer.

Subjects for the next presidential election poll are contacted using telephone numbers in which the last four digits are randoml

vovikov84 [41]

Answer: 0.3439

Step-by-step explanation:

Given :The last four digits for telephone numbers are randomly selected (with replacement).

Here , each position can be occupied with any of the digit independently .

Total digits = 10

Total digits other than 0 = 9

For each digits , the probability that it is not 0 = $\dfrac{9}{10}=0.9$

If we select 4 digits , The probability of getting no 0 = $(0.9)^4 =0.6561$

(By multiplication rule of independent events)

Now , the probability that for one such phone number, the last four digits include at least one 0. = 1- P(none of them is 0)

=1- 0.6561=0.3439

Hence, the probability that for one such phone number, the last four digits include at least one 0. is 0.3439 .

You multiply the binomial by the whole trinomial.

So 5x^2 (5x^3 - 6x^2 - 5) and then -2x (5x^3 - 6x^2 - 5)

then solve so it is:
25x^5 - 30x^4 - 25x^2 - 10x^4 + 12x^3 + 10x.

Then you simplify to:
25x^5 - 40x^4 + 12x^3 - 25x^2 + 10x

Left to Right

Distributive Property

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtraction Property of Equality

Algebra I

Terms/Coefficients
Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

2x - y = 11

x + 3y = -5

Step 2: Rewrite Systems

2x - y = 11

[Subtraction Property of Equality] Subtract 2x on both sides: -y = 11 - 2x
[Division Property of Equality] Divide -1 on both sides: y = 2x - 11

Step 3: Redefine Systems

y = 2x - 11

x + 3y = -5

Step 2: Solve for x

Substitution

Substitute in y [2nd Equation]: x + 3(2x - 11) = -5
[Distributive Property] Distribute 3: x + 6x - 33 = -5
Combine like terms: 7x - 33 = -5
[Addition Property of Equality] Add 33 on both sides: 7x = 28
[Division Property of Equality] Divide 7 on both sides: x = 4
