Calculate If 2x=8 find 5x+1

The two consecutive odd integers are -7 and -5, then the greater integer is -5.

Let's say that the smaller integer is x and the larger one is y.

Such that if both of these are odd and consecutive, then y = 2 + x.

We can now write:

8*y - x = -33

Replacing y by x + 2 we get:

8*(x + 2) - x = -33

8x + 16 - x = -33

7x = -33 - 16  = -49

x = -49/7 = -7

that is the smaller integer, then the next one is:

y = x + 2 = -7 + 2 = -5

The required value of the greater integer among the two consecutive odd integers is - 5.

An integer is a real number that has no decimal part.

suppose we have specified a particular odd no. 'O' then the consecutive odd integers are those numbers that arrive after every two numbers.

Given, an integer is subtracted from 8 times the next consecutive odd integer, the difference is -33.

Assuming the first odd integer to be 'n'.

So, the next consecutive odd integers are (n + 2), (n + 4)...

∴ 8(n + 2) - n = - 33.

8n + 16 - n = - 33.

7n = - 33 - 16.

7n = - 49.

n = - 49/7.

n = - 7.

So, the two integers are -7 and (-7 + 2) = - 5.

The value of x for the given triangle is 30°.

According to the question,

We have the following information:

We have a triangle.

Three angles of the triangle are x°, 65° and (x+55)°.

We know that the sum of all the three angles of a triangle is 180°.

So, the sum of these angles will be 180°.

Now, adding three angles:

x° + 65° + (x+55)° = 180°

(2x+120)° = 180°

2x = 180-120

2x = 60

x = 60/2 (2 was in the multiplication on the left hand side. So, it is in the division on the left hand side.)

x = 30°

Hence, the value of x in the angles of the given triangle is 30°.

Answer:

39% of 80 = 39.2

74% of 240 = 177.6

91% of 82 = 74.62

66% of 160 = 105.6

9% of 71 = 63.9

126% of 80 = 100.8

234% of 145 = 339.3

97.9% of 39 = 38.181

52% of 57.9 = 30.108

33% of 15.3 = 5.049

Step-by-step explanation:

In order to find the percentage of each equation, we will use the first one as an example. We take the 39%, and convert it to 0.39 and get rid of the %. Then, "of" means multiplication.

So, we have:

0.39 x 80 = 39.2

The equation of the line in slope-intercept form would be; y = -12x + 18

If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:

y = MX +c

To find the slope of a line, we the rate at which the value of 'y' is increasing as we increase the value of 'x' by one unit.

We have been given the point (1,6) and (2,-6)

y-y₁ = m(x-x₁)

m = (-6-6)/(2 -1)

m = -12/1

Now substitute;

y-y₁ = m(x-x₁)

y- 6 = -12(x- 1)

y- 6 = -12x + 12

y = -12x + 18

Hence, the equation of the line in slope-intercept form would be; y = -12x + 18

The oil prospector drills wells with a success probability of 0.15. The probability of finding the first productive well in the third attempt is 0.108375 and the probability that the prospector fails to find productive well in the first 5 attempts is  0.26724 or 26.724%

Let Y be the number of drilling trials on which the prospector will find the first productive well. As Y is a geometric random variable with p=0.15 where p is the probability of being successful on any drilling. Let q = 1- p be the probability of being unsuccessful in drilling a well. q = 1 - 0.15 = 0.85

The probability that the first productive well is found on the third attempt is when outcomes are independent

P(Y=3) = q * q * p = 0.85^2* 0.15 = 0.108375

We want to find the probability that 5 wells are drilled and not a productive one is found. That is we need to find p(Y>5). Y is a binomial random variable with several wells drilled at most as n. Given n=5 and p=0.15, q = 0.85

We know the geometric probability is p(y) = [tex]q^{y-1}[/tex]p

Then corresponding probabilities are added

p(Y≤ 5 ) = p(0) + p(1) +p(2) + p(3) +p(4) +p(5)= 0.73276

The values of f(2), f(4) and f(-3) for the function, f(x) = [tex]x^{2} -3x-4[/tex], are -6, 0 and 14 respectively.

According to the question,

We have the following information:

f(x) = [tex]x^{2} -3x-4[/tex]

Now, to find the values of each function we will put the values in place of x.

We will find the value of f(2) by putting 2 in place of x.

f(2) = [tex](2)^{2} -3(2)-4[/tex]

f(2) = 4-6-4

f(2) = -2-4

f(2) = -6

(We know that the numbers with negative sign are added but the result always remains in negative.)

We will find the value of f(4) by putting 4 in place of x:

f(4) = [tex](4)^{2} -3(4)-4[/tex]

f(4) = 16-12-4

f(4) = 4-4

f(4) = 0

Now, we will find the value of f(-3) by putting -3 in place of x:

f(-3) = [tex](-3)^{2} -3(-3)-4[/tex]

f(-3) = 9+9-4

f(-3) = 18-4

The dimensions are Width = 7 feets ; length = 20 feets

As given,

Meadow area is 140 square feet.

Height = W (smaller dimension and 2 sides)

Height = L (longer dimension and 1 side)

Fence yards equal 34 feet;

Hence,

L + W = 34

L + 2W = 34

L = 34 - 2W - - - (1)

Recall:

Area = L * W = 140

Substitute value of L

140 = (34 - 2W) * W

140 = 34W - 2W²

2W² - 34W + 140 = 0

W² - 17W + 70 = 0

W² - 10W - 7W + 70 = 0

W(W - 10) - 7(W - 10) = 0

(W - 10) = 0 or (W - 7) =0

W = 10 or W = 7

We choose the shorter width because length should be as long as possible:

W = 7

L + 2W = 34

L = 30 - 14

L = 20 feets

Answer:

Exterior angle = 20 degrees

Interior angle = 160 degrees

================================================

Explanation:

The phrasing "Each exterior angle measure is one eighth the measure of each interior angle" means,

exterior = (1/8)*(interior)

That rearranges to

interior = 8*(exterior)

Let's say x is the measure of the unknown exterior angle. That makes 8x the measure of the interior angle

The two must add to 180 to form a straight line.

interior + exterior = 180

8x + x = 180

9x = 180

x = 180/9

x = 20 is the measure of the exterior angle

8x = 8*20 = 160 is the measure of the interior angle

Note how 160+20 = 180 to verify our answers.
