21.99 * .25 = 5.4975

21.99 - 5.4975 =

16.4925

answer : $16.49

Answer:

$16.49

Step-by-step explanation:

21.99 x .75 = 16.4925

Rounded to the nearest cent is 16.49

If we are taking off 25%, that means that we are leaving on 75% or .75

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

Step-by-step explanation:

its ez

Answer:

C. or the 3rd one

Step-by-step explanation:

25/45 simplifies to 5/9 and 75/135 simplifies to 5/9

Answer:

It has zero solutions since its a contradiction

Answer:

No Solution

Step-by-step explanation:

1/2x+6=1/4(2x-24)

Distribute numbers in parenthesis

1/2x+6=1/2x-6

When you try to move both of the x's to the same side, you are left with 0x

6≠-6

Therefore no solution

Answer:

-1/12

Step-by-step explanation:

Formula to find the slope: Y2-Y1 / X2 - X1

Plug in:

(-4 + 7/2) / (4 + 2)

(-8/2 + 7/2) / (4 + 2)

( - 1/2) / (6)

= -1/12

Answer:

-1/12 negative one over 12

Answer: 50 inches would represent the scale drawing as 250 feet

Step-by-step explanation:

im not exactly sure what your asking but there brainliest if im right?

Answer:

The length of the building in the scale drawing is 31. 25 Inches

Step-by-step explanation:

Then,

If 0. 25 inches = 2 feet

Then x inches = 250 feet

cross multiply

x × 2 = 0. 25 × 2500

Multiply through, we then have

2x = 62. 5

Make 'x' the subject by dividing both sides by 2

2x/2 = 62. 5/ 2

x = 31. 25 Inches

Answer: the rate of change is 1/2

Step-by-step explanation:

The formula for slope is y2 - y1/ x2 - x1

I picked points (2,2) (x1 & y1) and (6,4) (x2 & y2)

4 - 2 = 2

6 - 2 = 4

2/4 is the rate of change, and 1/2 is 2/4 simplified

Answer:

12/32

Step-by-step explanation:

3 * 4 = 12

8 * 4 = 32

so the most logical answer is 12/32

Answer: B

Explanation:

Correct way to write down co-ordinates: x,y

Dog 1's position: (-6,3)

Dog 2's position: (-6,-3)

Similarity: Both co-ordinates have -6 on the X axis (left to right line)

Difference: Dog 2's Y co-ordinate is NEGATIVE 3 while dog 1's Y co-ordinate is POSITIVE 3

The position is going to be reflected across the X axis because their X co-ordinates are the same, so dog 1 will be on the positive section for the Y axis (line that goes up and down) while Dog 2 will be on the negative section of the Y axis since it has negative 3 as its Y co-ordinate.

The answer you are looking for is 33807

Answer:

y:=33806.526

y=33807.(Rounded off)

Step-by-step explanation:

y=(34567(1−0.022))

Solve for y

y=50016903263​=33806500263​=33806.526

Steps for Solving Linear Equation

y=(34567(1−0.022))

Subtract 0.022 from 1 to get 0.978.

y=(34567×0.978)1

Multiply 34567 and 0.978 to get 33806.526.

y=33806.5261

Calculate 33806.526 to the power of 1 and get 33806.526.

y=33806.526

Assign y

y:=33806.526

y=33807.

Answer: {5, 1, 3}

Step-by-step explanation:
Plug in the numbers in parentheses for x.

a: f(-2) = 1-2(-2) = 1+4 = 5

b: f(0) = 1-2(0) = 1-0 = 1

c: f(2) = 1-2(2) = 1-4 = -3

Answer: 5, 1, -3

Step-by-step explanation:

1. f(-2) = 1-2x(-2) = 1+4 =5 ; f(-2)= 5

2. f(0) = 1-2(0) = 1-0 = 1 ; f(0) = 1

3. f(2) = 1-2(2) = 1-4 = -3 ; f(2) = -3

Answer: 1/2, 0.51, 11/20

Step-by-step explanation:

Use 100 as a common denominator so you can compare all the numbers in like terms:

1/2 = 50/100

0.51 = 51/100

11/20 = 55/100

Answer:

[tex]\frac{1}{2} 0.51, \frac{11}{20}[/tex]

Step-by-step explanation:

First, you want to change the decimal into a fraction.  0.51= [tex]\frac{51}{100}[/tex]

Then, find the common denominator.  In my example, I used 100.  Find the equivalent fraction for the fractions with 100 as their denominator

[tex]\frac{11}{20} = \frac{55}{100} \\\\\ \frac{1}{2} = \frac{50}{100}[/tex]

Next, line them up in order of their numerators

[tex]\frac{50}{100} \frac{51}{100} \frac{55}{100}[/tex]

Finally, match the new fraction with their reduced fraction or decimal:

[tex]\frac{1}{2} = \frac{50}{100} \\\\0.51 = \frac{51}{100} \\\\\frac{11}{20} = \frac{55}{100}[/tex]
