Solve for x. 3(2x-3) +42-2=0

Mathematics
1 answer:
baherus [9]3 years ago
6 0

Answer:

x = -31/6 or -5.16

Step-by-step explanation:

3(2x-3) + 49 -2 = 0

Distribute 3 through the parenthesis

3 (2x-3) + 49 - 2 = 0

6x - 9 + 42 - 2 = 0

Calculate the sum or difference

6x - 9 + 42 - 2 = 0

6x + 31 = 0

Move constant to the right side and change its sign

6x + 31 = 0

6x = -31

Divide both sides of the equation by 6

6x = -31

x = -31/6 or -5.16

one town, 64% of adults have health insurance. What is the probability that 10 adults selected at random from the town all have
Katena32 [7]

Answer:

The probability that 10 adults selected at random from the town all have health​ insurance is 0.01153.

Step-by-step explanation:

Consider the provided information.

One town, 64% of adults have health insurance.

Let p = 64% = 0.64

Therefore, q=1-0.64=0.36

We need to find the probability that 10 adults selected at random from the town all have health insurance

Use the formula: P(x)=^nC_r(p)^r(q)^{n-r}

Here, the value of r is 10.

Substitute the respective values in the above formula.

P(x)=^{10}C_{10}(0.64)^{10}(0.36)^{10-10}

P(x)=(0.64)^{10}(0.36)^{0}\\P(x)=(0.64)^{10}\\P(x)\approx0.01153

Hence, the probability that 10 adults selected at random from the town all have health​ insurance is 0.01153.

HELP ASAP I WILL GIVE BRAINLIEST
tatuchka [14]

Answer:

A

Step-by-step explanation:

Taking the square root of both sides, you get

\sqrt{x^2} = \pm\sqrt{180}

which simplifies to

x = \pm\sqrt{180}

The square root of 180 is approximately 13.42 and since it is the plus or minus square root, the answer is A, -13.42, 13.42.

I will give 25 points and brainy from right answers (Please answer all!)!!!
DIA [1.3K]
1. D.  because the angels of KRC and CRH added together is 180 degrees. Which equals a straight line.

2. Answer is A . BHR is equal to NHD, so it is 8x. But we need to find x first.
The right angle in the picture is 8x + (9x +5)
90 =8x + 9x +5
90 = 17x + 5
85 = 17 x
5 = x.
X is 5 so 8x is 40.

3. B. The opposite angles are equal to each other. and the sum of two angles side by side equal 180.
6x - 82 = 3x +23 
group like terms
6x - 3x = 23 + 82
3x = 105
x = 35.
Answer is B
4.B.   a complement angle added together will get you 90.
90 - 41 = 49
Answer is B
