(1.2÷0.375−0.2)/(6 4/25 ÷15 2/5 +0.8) = (0.016÷0.12+0.7)/x

Answers

Answer:

x=1/3

read below to find out how I solved!

Step-by-step explanation:

break it down.

First do 1.2÷0.375−0.2 = 1.2.

it is now 1.2/(6 4/25 ÷15 2/5 +0.8) = (0.016÷0.12+0.7)/x

now do 6 4/25 ÷15 2/5 +0.8 = 3

it is now 1.2/3 = (0.016÷0.12+0.7)/x

now do 0.016÷0.12+0.7 and that is 5/6

now you have 1.2÷3 = 5/6 ÷ x

solve for x and you should get x = 1/3!!

Answers

Answer: 5√10.

Step-by-step explanation:

250 is split into its prime factors as 2 * 5 * 5 * 5 which implies √250 = √(2 * 5 * 5 * 5). Now we can simplify this further by pulling out the number which is multiplied to itself. This gives √250 = 5 * √(2 * 5) = 5√10. Therefore the square root of 250 is √250 = 5√10.

The line whose slope will be same as that of the graph given, will be the line parallel to the given line.

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Given is a graph of a line.

For a given line to be parallel to the given line, its slope should be same as that of the line plotted. Since the graph is not given, we can make an estimate for the equation of the line parallel to the given line. The four equations given will have their slopes as mentioned -

[A] -   4x + 5y = - 10       [m] = -4/5

[B] -   4x - 5y = 0           [m] = 4/5

[C] -   5x + 4y = 24        [m] = -5/4

[D] -   5x - 4y = -8          [m] = 5/4

Now, the line whose slope will be same as that of the graph given, will be the line parallel to the given line.

Therefore, the line whose slope will be same as that of the graph given, will be the line parallel to the given line.

Breannas cat weighs 3200 grams. Her neighbors cat weighs 4.68 kilograms. What is the difference, in grams, of the weights of two cats

Answers

Answer:

1480 grams.

Step-by-step explanation:

3200 grams = 3200/1000

= 3.2 kgs.

Difference in weight = 4.68 - 3.20

= 1.48 kgs

= 1480 grams.

Answer:

3,200g  - 4.68kg = 1480

Step-by-step explanation:

4.68k g = 4,680 g

1 kg = 1,000 g

4,680 - 3,200 = 1480

∠ DBC = 16°

Step-by-step explanation:

∠ ABD + ∠ DBC = ∠ ABC , substitute values

2x + 15 + x - 30 = 123 , that is

3x - 15 = 123 ( add 15 to both sides )

3x = 138 ( divide both sides by 3 )

x = 46

Thus

∠ DBC = x - 30 = 46 - 30 = 16°

Answer:

Step-by-step explanation:

9x+7 when x=3

Plug 3 into the equation for the variable x

So, it would be 9(3)+7

Multiply 9×3 together to get 27

Finally, add 27 and 7 together

The answer should be 34

Answer:

x=1

Step-by-step explanation: 9x+7=16

Subtract 7 from both sides.

9x=16−7

Subtract 7 from 16 to get 9.

9x=9

Divide both sides by 9.

if length of the square is 7-x and width is 19-3x then what is the value of x Some transportation experts claim that it is the variability of speeds, rather than the level of speeds, that is a critical factor in determining the likelihood of an accident occurring (Update, Virginia Department of Transportation, Winter 2000).
