Simplify 4/9 - 5/12 + 1/4

Answer:

9-28= 21

Step-by-step explanation:

She made profit because she lost 9 dollars, and then gained 28$ back, which would then equal to $21, so Andrea made a profit of $21.

Answer:

E. None of these

Step-by-step explanation:

Points: (11, -4), (13, -7)

slope = m = (y2 - y1)/(x2 - x1) = (-7 - (-4))/(13 - 11) = (-7 + 4)/2 = -3/2

y - y1 = m(x - x1)

y - (-4) = (-3/2)(x - 11)

y + 4 = (-3/2)x + 33/2

y + 8/2 = (-3/2)x + 33/2

y = (-3/2)x + 25/2

Answer: E. None of these

Step-by-step explanation:

A(11,-4) B(13,-7)

x1 y1 x2 y2

y=mx+c

-4=11m+c -(i) -7=13m+c -(ii)

Subtract equation (ii) from (i)

-7=13m+c

-4=11m+c

+ - -

-3=2m

2m=-3

m=-3/2

put m=-3/2 in equation (ii)

-7=13*(-3/2)+c

c=-7+39/2

c=(-14+39)/2

c=15/2

y=mx+c

y=-3/2x+15/2

y=(-3x+15)/2

2y=-3x+15

2y+3x-15=0

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.

Answer:

C

Step-by-step explanation:

I’m pretty sure

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

1885/65

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

Answer:

34

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.

​Divide 9 by 9 to get 1.

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!!

Step-by-step explanation:

Distributive property is as follows :

a(b+c) = ab + ac

Felix used place value and the distributive property to rewrite the expression 9(278).

Place value of 278 = 200 + 70 +8

He has done like : 9(278) = 9(200 + 70 + 8). Now, the steps are as follows :

9(278) = 9(200 + 70 + 8)

= 9(200)+9(70)+9(8)

= 1800 + 630 +72

= 2502

Hence, option (d) "Distribute the 9 to each addend. Find the sum of (1,800 + 630 + 72)" should be the correct answer.
