Aida applied the distributive property to write the equivalent expressions below.

15 + 21 = 3 (4 + 8)

What is Aida’s error?
Aida used 3 as the factor, which is not common to 15 and 21.
Aida did not correctly divide by the common factor to get (4 + 8).
Aida did not apply the correct operations to the expressions.
Aida wrote two expressions that are not equivalent.

Answer:

X = 20

Angles are both equal to 100 degrees

Step-by-step explanation:

Assuming that 7x-40 = 2x +60

1. Order of Operations

2. 5x = 100

3. divide 100 by 5

4. x = 20

5. Plug 20 into both equations

6. 7(20) - 40 = 100

   2(20) + 60 = 100

7. Both angles are equal to 100 degrees

Answer:

y=-2

Step-by-step explanation:

First, find the slope using the slope formula: m=y2-y1/x2-x1

Plug the numbers into the equation and get 0

Using the slope and one of the coordinates, put the equation into point-slope form: y-y1=m(x-x2)

y+2=0(x+4)

Distribute and simplify to get the final answer.

y+2=0+0

y=-2

Answer:

The correct option is Option C

Step-by-step explanation:

We are given the lines: [tex]y=-\frac{4}{5}x+2 \ and \ \ y=-\frac{5}{4}x-\frac{1}{2}[/tex]

The lines are perpendicular if they have opposite slopes i,e [tex]m_1=-\frac{1}{m_2}[/tex]

In line 1 the slope is [tex]-\frac{4}{5}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-4/5)

In line 2 the slope is [tex]-\frac{5}{4}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-5/4)

The opposite reciprocal of -4/5 is 5/4  

So, the lines are not perpendicular as their slopes are not opposite reciprocal of each other.

If the lines are parallel there slope must be same. Hence lines are not parallel as well.

So, The correct option is Option C

Answer:

S= (0,0)

T= (3,-2)

counterclockwise

Q= (-5,2)

R= (1,3)

S= (0,0)

T= (-3,-2)

Step-by-step explanation:

this might not be right im a little rusty on my transformations but here goes nothing.

i dont know if this is a clockwise or a counter clockwise rotation so ill do both options.

clockwise (x,y) - (y,-x)

q=(2,5) - (5,-2)

r=(3,-1) - (-1,-3)

s=(0,0) - (0,0)

t=(-2,3) - (3,2)

counterclockwise (x,y) - (-y,x)

q=(2,5) - (-5,2)

r=(3,-1) - (1,3)

s=(0,0) - (0,0)

t=(-2,3) - (-3,-2)

Answer:

(X-x0)^2 +(y-y0)^2= r^2

Answer:

$7.55

Step-by-step explanation:

First, add the prices to get the grand total.

$20.95 + $11.50 = $32.45

Now, subtract that from the total that was paid.

$40.00-$32.45 = $7.55

(Hope this helped in some kind of way and can i get brainlest? okay bye have a blessed day!)

The actual number of days required to buy a bicycle will be 20 days.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Mr. Olivera wishes to purchase a $184 bicycle for each of his two children. He intends to save the $9 he normally spends on lunch to purchase the bikes.

Let 'x' be the number of days. Then the inequality is given as,

9x ≤ 184

Simplify the equation, then we have

9x ≤ 184

x ≤ 184 / 9

x ≤ 20.44

The actual number of days required to buy a bicycle will be 20 days.

Answer:

The correct answer is Option 2:

[tex]7+(\frac{1}{5}+n) = (7+\frac{1}{5})+n[/tex]

Step-by-step explanation:

Associative property consists of three quantities. Associative property for addition states that the result of adding three numbers will be same no matter what the order of addition is.

Let a,b and c be three numbers

Then associative property can be stated as:

[tex]a+(b+c) = (a+b)+c[/tex]

Now looking at the options it can be observed that the following choice shows the associative property

[tex]7+(\frac{1}{5}+n) = (7+\frac{1}{5})+n[/tex]

Hence,

The correct answer is Option 2:

[tex]7+(\frac{1}{5}+n) = (7+\frac{1}{5})+n[/tex]

When the mean number of points scored per game next season is 60, the model predicts that the mean home attendance will be 11902

The function that predicts the attendance is given as:

[tex]y = -7628+325.5x[/tex]

When the mean number of points scored per game next season is 60, it means that the value of x is 60

i.e. x = 60

Substitute 60 for x in the function

So, we have:

[tex]y = -7628+325.5 \times 60[/tex]

Evaluate the product

[tex]y = -7628+19530[/tex]

Add -7628 and 19530

[tex]y = 11902[/tex]

Hence, the model predicts that the mean home attendance will be 11902

Answer:

The rate is 15 minutes per meter.

Step-by-step explanation:

It takes 9 minutes to fill a depth of  meters.

Filling   meters take 9 minutes time.

Filling 3 meters of the aquarium takes  = 45 minutes time (Multiplying by 5 both the numbers).

In order to fill 1 meter of the aquarium it will take  minutes (Dividing by 3 both the numerical values).

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

Work Shown:

8 minutes = (2/5) meters

5*(8 minutes) = 5*( (2/5) meters )

40 minutes = 2 meters

40/2 minutes = 2/2 meters

20 minutes = 1 meter

The unit rate in minutes per meter is 20 minutes per meter.

In other words, it takes 20 minutes to raise the level 1 meter.
