Covert 298.4 to a fraction

Answer:

x = -25

Step-by-step explanation:

[tex]3 - \frac{x}{5} = 8[/tex]

[tex]5(3 - \frac{x}{5} ) = 5 \times 8[/tex]

[tex]5 \times 3 - 5 \times \frac{x}{5} = 5 \times 8[/tex]

[tex]15 - 5 \times \frac{x}{5} = 40[/tex]

[tex]15 - x = 40[/tex]

[tex] - x = 40 - 15[/tex]

[tex] - x = 25[/tex]

[tex]x = - 25[/tex]

Answer:

x = - 25

Step-by-step explanation:

Given

3 - [tex]\frac{x}{5}[/tex] = 8 ( subtract 3 from both sides )

- [tex]\frac{x}{5}[/tex] = 5 ( multiply both sides by 5 to clear the fraction )

- x = 25 ( multiply both sides by - 1 )

x = - 25

Answer:

Bring the first dot down to 1 but leave it in the 15 row

Then the middle one bring to the right one line (to 30) and then down two rows (to 2)

And the one on the right bring one line to the right

Answer:

[tex]y=-\frac{5}{2}x-24[/tex]

Step-by-step explanation:

[tex]2x-5y=-12\\5y=2x+12\\y=\frac{2}{5}x+\frac{12}{5}\\[/tex]

if two lines perpendicular,

[tex]m_{1} .m_{2}=-1\\ \frac{2}{5} .m_{2}=-1\\m_{2}=-\frac{5}{2}[/tex]

the line perpendicular to this line is

[tex]y=-\frac{5}{2}x+k[/tex] ; k ∈ R

the line passes through the point (10,-1)

so,

[tex]-1=-\frac{5}{2} (10)+k\\-1=-25+k\\k=-24[/tex]

∴the equation of the line perpendicular to 2x-5y=-12 that passes through the point (10,-1) is

[tex]y=-\frac{5}{2}x-24[/tex]

An compound inequality that describes the acceptable weights for a 20 oz box is 19.25 ≤ x ≤ 20.75.

The absolute value of a number is defined as its magnitude irrespective of the sign of the number. To determine the absolute value of a real number, we consider only the number and remove the sign. It can only be a non-negative value.

We are Given that, cereal manufacturer has a tolerance of 0.75 oz for a box of cereal that is supposed to weigh 20 oz.

Let the weight of cereal box be; w

Now, the inequality is

20-0.75 ≤ x ≤ 20+0.75

Add 20 on both sides of an inequality, we get

19.25 ≤ x ≤ 20.75

Here, 19.25 ≤ x ≤ 20.75

Therefore, an absolute value inequality to find the range of acceptable weights is 19.25 ≤ x ≤ 20.75.

Explanation:

First we need to find the volume of the cube

volume = length*width*height = 4*4*4 = 64 cubic cm

Then we'll divide the mass over this volume to get the density

density = mass/volume

density = (12 grams)/(64 cm^3)

density = (12/64) grams per cm^3

density = 0.1875 grams per cm^3

The notation cm^3 is another way of saying "cubic centimeter" as shorthand.

Step-by-step explanation:

15 x 64 = 15 x (60 + 4)

= (15x60) + (15x4)

= 900 + 60

= 960

Answer:

720

Step-by-step explanation:

Heck that's a lot of erasers!!!

36 (erasers per child) x 20 (the number of children) = 720 (number of erasers)

Answer:

minutes left = 120 - x (minutes used)

Step-by-step explanation:

1 hour = 60 minutes

minutes left = 2 hr x 60 minutes /hr - x (minutes used)

minutes left = 120 - x (minutes used)

Answer:

x=73, y=107, z=73

Step-by-step explanation:

Each horizontal should equal 180 therefore x would be 180-107 and so on.

Answer:

[tex] \frac{x}{3} + 7 = 10 \\ \frac{x}{3} = 10 - 7 \\ \frac{x}{3 } = 3 \\ x = 3 \times 3 \\ x = 9 \\ thank \: you[/tex]

Answer:

x=9

Step-by-step explanation:

x/3 +7 = 10

Subtract 7 from each side

x/3 +7-7 = 10-7

x/3 = 3

Multiply each side by 3

x/3*3 = 3*3

x=9

Answer:

-5

Step-by-step explanation:

We can use the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 4 - -1)/( 9 - 10)

    ( 4+1)/( 9-10)

    5/ -1

Answer:

70% of the members voted for Jina.

Step-by-step explanation:

votes : members

  28   :      40

  70   :      100

70% of the members voted for Jina.

Answer:

70%

Step-by-step explanation:

To find the percentage, turn 28/40 into a fraction:

28

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

40

Then, keep simplifying it, or dividing it by the GCF.

28 14 7

------------ ----> ----------- ----> -----------

40 20 10

7/10 in a percentage is 70 percent since 7/10 can turn into 70/100

Answer:

30 cm

25 cm

15 cm

Step-by-step explanation:

x = longest side

y = shortest side

x + y + 25 = 70

x = 2y

using the second equation as substitute in the first equation we get

2y + y + 25 = 70

3y = 45

y = 15 cm

x = 2y = 2×15 = 30 cm

Answer:  1  1/2

You can write this as 1 & 1/2

The whole part is 1. The fractional part is 1/2

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

Explanation:

Let's say we had 18 cookies to hand out to 12 students.

How many cookies does each student get?

Using a calculator shows that 18/12 = 1.5 which means they get one whole cookie each

The leftovers is 18-12 = 6

Then notice how 6/12 = 1/2

So that's how the improper fraction 18/12 becomes the mixed number 1 & 1/2

So each student gets 1 full cookie, plus half a cookie.

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

Or we could do the problem like this

18/12 = (12+6)/12

18/12 = (12/12)+(6/12)

18/12 = 1 + (1/2)

18/12 = 1 & 1/2

Answer:

ok the answer is wrong because

when you multiply them you get

-25y^2 + 50y -21

because 5y*-5y is -25y^2 not 21y^2

Answer:

i think the answer is 1 1/8 (or 1.125)

Step-by-step explanation:

1. -3/8 / -1/3 = 3/8 * 3/1 = 9/8

2.Simply this improper fraction to a mix number

9/8 = 1 1/8 (and since 1 is going into the 9,8 it cannot be reduced further)

3rd 1 1/8 is recognized as 1.125

Answer:

C = (1, 14 )

Step-by-step explanation:

The coordinates of the midpoint are the average of the x and y coordinates of the endpoints.

Find the average of endpoints and equate to coordinates of midpoint

A (5, - 2 ) , let C = (x, y ) , then

[tex]\frac{x+5}{2}[/tex] = 3 ( multiply both sides by 2 )

x + 5 = 6 ( subtract 5 from both sides )

x = 1

and

[tex]\frac{y-2}{2}[/tex] = 6 ( multiply both sides by 2 )

y - 2 = 12 ( add 2 to both sides )

y = 14

Coordinates of C = (1, 14 )

Step-by-step explanation:

Distance = √(x_2 - x_1)² + (y_2 - y_1)²

Distance = √[(-a) - a]² + (b - b)²

Distance = √[-2a]² + (0)²

Distance = √4a²

Distance = 2a
