solve what is 1/2 x 15

Answer:

75

Step-by-step explanation:

86+79+68+83=316

391-316=75

Answer:

75 newspapers

Step-by-step explanation:

391 is equal to the combination of all the newspapers Nicholas sold over those 5 days. This can be written as an equation:

391 = 86 + 79 + 68 + 83 + x

x represents the number of newspapers Nicholas sold on Thursday.

Now let's solve for x:

First, combine like terms:

391 = 316 + x

now subtract 316 from both sides to isolate x:

391 - 316 = 316 - 316 + x

75 = x

Nicholas sold 75 newspapers on Thursday.

Answer:

24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1

Step-by-step explanation:

Given the following temperature values :

2, 6.9, 17 1/2 , −5.1, 24, − 1/4 , and 1.45.

Ordering the values above from greatest to least ; (descending order)

Expressing all temperature values in the same format :

Let's make sure all values are in decimal to make comparison easier :

2.0

6.9

17 1/2 = 35/2 = 17.5

-5.1

24.0

-1/4 = - 0.25

1.45

We begin from the temperature value which is highest :

24 > 17.5 > 6.9 > 2.0 > 1.45 > - 0.25 > - 5.1

Hence ;

24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1

Answer:

B

Step-by-step explanation:

The question said the person bought a shirt which means 1 and 3 pairs of pants which means multiple but we don’t know how many so we substitute that ? for a x so 15 + 3x =117

Answer:

B

Step-by-step explanation:

It is B because we do not know the price of the three pants but know that the total is 117 and the price of the t-shirt is $15

Answer:

Explained below.

Step-by-step explanation:

(1)

Sample space is a set of all possible outcomes of an experiment.

The sample space in this case is:

S = {HF, HW, MF, MW}

(a)

Compute the value of P (W) as follows:

P (F) + P (W) = 1

P (W) = 1 - P (F)

P (W) = 1 - 0.50

P (W) = 0.50

(b)

Compute the value of P (MF) as follows:

P (HF) + P (MF) = P (F)

P (MF) = P (F) - P (HF)

P (MF) = 0.50 - 0.20

P (MF) = 0.30

(c)

Compute the value of P (M) as follows:

P (M) = P (MF) + P (MW)

P (M) = 0.30 + 0.10

P (M) = 0.40

Compute the value of P (H) as follows:

P (H) + P (M) = 1

P (H) = 1 - P (M)

P (H) = 1 - 0.40

P (H) = 0.60

Answer:

Slope is -2 and y intercept is 3.5

Step-by-step explanation:

Basically you change it into slope intercept form by adding 3.5 on both sides to get y by itself, then you have the slope and the y intercept.

SSS (side, side, side) SSS stands for "side, side, side" and means that we have two triangles with all three sides equal. ...

SAS (side, angle, side) ...

ASA (angle, side, angle) ...

AAS (angle, angle, side) ...

HL (hypotenuse, leg)

Step-by-step explanation:

Answer:

 y = 2x - 2

Step-by-step explanation:

Slope-intercept form is y = mx + b

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

y - [tex]y_{1}[/tex] = m ( x - [tex]x_{1}[/tex] )  

(1, 0)

(2, 2)

(3, 4)

(4, 6)

m = [tex]\frac{2-0}{2-1}[/tex] = 2

y = 2( x - 1 )

y = 2x - 2

Step-by-step explanation:

Answer:

Yes, he has enough money to get his things.

Step-by-step explanation:

3 (the amount of grass seed bags he's buying)  x 23 (how many dollars it costs) = 69

3 (the amount of flower pots he's buying) x 15 (how many dollars it costs) = 45

69 + 45 = 114

He will have $6 left over his purchases.

Answer

the second one

Answer:

Evan can go on 30 rides   (based on the assumption that Evan's parent gave him $20)

Step-by-step explanation:

Given that:

The admission to the fair  = $5

The cost per ride = $0.50

Let assume that the number of ride Evan can go = x

So if The cost per ride = $0.50

x ride = $0.50x

We are not told that he is given money by anybody, but let assume his parent gave him $20,

Then, if Evan pays $5 for admission into the fair. Then he will have $(20-5) = $15 left

The relation expressing how many rides Evan can go is:

0.5x = 15

Since the cost per ride = $0.5

x rides cost $15/0.5

x = 15/0.5

x = 30

Hence, Evan can go on 30 rides

Step-by-step explanation:

Answer: y = -2x² + 920x - 84168

suppose: the equation of the parabola is y = ax² + bx + c

because the parabola passes through (126,0); (134,3200); (334,0)

=> we have the equations:

126².a + 126b + c = 0

134².a + 134b + c = 3200

334². a + 334b + c = 0

⇒ a = -2

    b = 920

    c = -84168

=>  the equation of the parabola is y = -2x² + 920x - 84168

Answer:

[tex] y = 5 - x [/tex]

Step-by-step explanation:

The graph of the equation that will contain the points (2, 3) and (3, 2) is the graph that has a slope value that is equivalent to the slope value of the line running through the two points.

Slope of the line running through (2, 3) and (3, 2):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 3}{3 - 2} = \frac{-1}{1} = -1 [/tex].

Slope (m) = -1.

The equation, [tex] y = 5 - x [/tex] , is given in the slope-intercept form, which means it has a slope value of -1. I.e. the term "-x" is equivalent to -1x. So therefore, the graph of the equation that contains the points (2, 3) and (3, 2) is [tex] y = 5 - x [/tex].

I would say -2

Answer:  17/18

In words, this is seventeen eighteenths

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

Work Shown:

4/9 + 9/18

8/18 + 9/18 ... see note below

(8+9)/18

17/18

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

note: To go from 4/9 to 8/18, we multiply top and bottom by 2. So that's why 4/9 = 8/18.

The diagram below shows a visual representation of why 4/9 = 8/18.

In the top row, I've drawn out 9 rectangles of the same size. Then I've shaded 4 of the 9 rectangles to represent the fraction 4/9. In the bottom row, I've cut each of those 9 rectangles into two smaller equal pieces, so we have 9*2 = 18 rectangles now. Note how the shaded regions are the same size, so this shows 4 green regions doubles to 2*4 = 8 yellow regions; therefore 4/9 is the same as 8/18.

Answer: its 17/18

Good luck! <3

Answer:

7 to the 6th power is conventionally written as 76, with superscript for the exponent, but the notation using the caret symbol ^ can also be seen frequently: 7^6.

76 stands for the mathematical operation exponentiation of seven by the power of six.

As the exponent is a positive integer, exponentiation means a repeated multiplication:

The exponent of the number 7, 6, also called index or power, denotes how many times to multiply the base (7).

Thus, we can answer what is 7 to the 6th power as

7 to the power of 6 = 76 = 117649.
