.24 as a fraction is 6/25

Step-by-step explanation:

1) Let convert our decimal into a percentage so we could write it in the not simplified fraction of 0.24:

.24 = 24% = 24/100

2) Now since we have 24/100, we could now simplify:

24/100 = 12/50 = 6/25

The error in the solution is adding 9 and 2 before the multiplication and the new expression is (2 x 3) +  9

The equation and the steps are given as

9 + 2 x 3 = 11 x 3 = 33

The above solution is incorrect

This is so because the product has a higher order of precedence

So, it must be evaluated first

So, the correct solution is

9 + 2 x 3 = 9 + 6 = 15

To rewrite the expression such that the product is done first, we introduce the use of brackets

So, we have

9 + (2 x 3)

This gives

(2 x 3) +  9

Hence, the result of the products is (2 x 3) +  9

Answer:

False

Step-by-step explanation:

The dependent variable changes, the size of the order will change depending on how many employes want a shirt.

|-3| means "the absolute value of 3", which is a way of saying how far away from zero the number -3 is on the number line.

The definition of absolute value goes like this:

[tex]|x| = \begin{cases} x & \text{if } x \ge 0 \\ -x & \text{if } x < 0 \end{cases}[/tex]

In other words, if the number [tex]x[/tex] inside the absolute value bars is already positive or zero, we leave it alone. If instead [tex]x[/tex] is negative, we multiply it by -1 to recover the positive version of that number.

Since -3 is negative, it follows that |-3| = -(-3) = 3. So the expression 3 |-3| is equivalent to 3 • 3 = 3² = 9.

Speed of the car of Lewis family = 38 miles/hours

What is speed?

Distance travelled by an object per unit of time is called speed.

If d is the distance travelled and t is the time taken, then speed is calculated by-

Speed = [tex]\frac{d}{t}[/tex]

Here, speed is a scalar as the direction is not taken into account.

Distance drove by  Lewis family to the river = 45.6 miles

Time taken by the Lewis family to go to the river  = 1.2 hours

Speed of the car of Lewis family = [tex]\frac{45.6}{1.2}[/tex]

By solving a system of equations we can see that Olivia spent $14 and Camiller spent $37.

Let's define two variables:

We know that " Camille spent $14 less than three times what Olivia spent" so we can write:

y = 3*x - 14

And "In total, they spent $54"

x + y = 54

Then we have a system of equations:

y = 3*x - 14

x + y = 54

Replacing the first equation into the second one, we get:

x + 3x- 14 = 54

4x - 14 = 54

4x = 54 + 14

4x = 68

x = 68/4 = 17

Now that we know the value of x, we can try to find the value of y.

y = 3x - 14 = 3*17 - 14 = 37

So Olivia spent $14 and Camiller spent $37.

origin

Explanation:

In the graph:

• The vertices of Figure A are: (0,4), (-9,3) and (-9,6)

• The vertices of Figure A' are: (1,-4), (10,-3) and (10,-6)

If Figure A is translated 1 unit to the left, the vertices are:

Next, a rotation of 180° counterclockwise about the origin gives:

These are the vertices of Figure A'.

Thus, the correct transformation is: translated 1 unit to left and then rotated 180° counterclockwise about the origin.

The correct choice is C.

The correct equation to solve for x is 2(2x-15)=2x-8 , and the value of x is 11 .

in the question ,

from the given figure , we can see that RL=LQ   and PK=KQ which means

that L and K are the mid points of sides RQ and PQ respectively .

The Mid Point Theorem states that

If the line segment adjoining the mid points of any of the sides of the triangle then the line segment is said to be parallel to the third  side and is half of the length of  third side .

which means LK parallel to RP and RP/2=LK  ( ... by mid point theorem)

Substituting the values of LK = 2x-15  and RP = 2x-8 .

(2x-8)/2=2x-15

Multiplying both sides by 2

2x-8 = 2(2x-15)

So, the equation to solve for x is 2(2x-15)=2x-8

Simplifying further

2x-8 = 4x-30

4x-2x= 30-8

2x = 22

x = 11

Answer:

x=4/15

Step-by-step explanation:

first you need to make common denominators for 1/5 and 1/3

the common denominator is 15

5*3=15, 3*5=15. 1*3=3, 1*5=5

new equation:3x-3/15=x+5/15

now subtract x from both sides: 3x-3/15=x+5/15

                                                     -x          -x

                                                     2x-3/15=5/15

now you can add 3/15 to 5/15

2x=8/15

now for the last step, divide by 2 because there are 2 x's

2x/2=x         8/15 /2=4/15

x=4/15

Answer:

4/15

Step-by-step explanation:

3x-1/5 = x+1/3

make a common denominator

3x -3/15 = x + 5/15

next you can take away one x from both sides

2x - 3/15 = 5/15

then we want to have x alone on one side and everything else on the other

2x = 5/15 + 3/15

2x = 8/15

1x = 8/15 ÷ 2

1x = 8/30

simplify that

x = 4/15

The y-intercept of the line that passes through points (-2,6) and (1,6) in an ordered pair is ( 0,6 ).

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

The slope of a line is expressed as change in y over change in x.

Slope m = (y₂-y₁)/(x₂-x₁)

Given the data in the question;

Point A ( -2,6 )

Point B ( 1, 6 )

First, we determine the slope of the line.

Slope m = (y₂-y₁)/(x₂-x₁)

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

Slope m = ( 0 )/( 1 + 2) )

Slope m = ( 0 )/3

Slope m = 0

Now, we can determine the y-intercept b, using the slope and coordinates of 1 point.

y = mx + b

6 = (0)(1) + b

Solve for b

6 = 0 + b

b = 6

Therefore, the coordinates of the y-intercept is ( 0,6 ).

Answer:

x - intercept = - 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

x - 2y = 7 ( subtract x from both sides )

- 2y = - x + 7 ( divide through by - 2 )

y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{7}{2}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{1}{2}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2 , then

y = - 2x + c ← is the partial equation of the perpendicular line\to find c substitute (- 3, 4 ) into the partial equation

4 = 6 + c ⇒ c = 4 - 6 = - 2

y = - 2x - 2 ← equation of perpendicular line

to find the x- intercept let y = 0 into the equation and solve for x

- 2x - 2 = 0 ( add 2 to both sides )

- 2x = 2 ( divide both sides by - 2 )

x = - 1

the x- intercept of the perpendicular line is - 1 or (- 1, 0 )

She uses 800 mL of solution A; that is, 2% of those 800 mL is alcohol

Alcohol on a:

2% of 800 = 2*800/100 = 16mL

If we use x mL of b, the amount of alcohol is:

5% of x = 5*x/100 = x / 20

Total amount of alcohol: 16 + x/20

Total amount of solution mixture: 800 + x

The ratio:

(16 + x/20) / (800 + x) = 3%

(16 + x/20) / (800 + x) = 3/100

1600 + 5x = 2400 + 3x

Solving for x:

5x - 3x = 2400 - 1600
