A dozen more than a number minus twice the number

Answer:

r = 2

Step-by-step explanation:

I'm assuming we're finding r

11 = 1 + 3r + 2r

Add up the numbers with r

11 = 1 + 5r

Subtract both sides by 1

11 = 1 + 5r

-1  -1

10 = 5r

Divide both sides by the coefficient, 5, to isolate the variable, r

10/5 = 5r/5

r = 2

Step-by-step explanation:

11=1+5r

11-1=5r

5r=10

r=10/5

r=2

Answer:

$3.94

Step-by-step explanation:

$30.42 + $9.89 + $5.75 = £46.06

$50.00 - $46.06 = $3.94

The change should you expect is $3.94

We have given,

At the store, you buy a backpack for $30.42, a binder for $9.89 and a combination lock for $5.75.

We have change should you expect therefore we have,

Total cost is the sum of expenses a company needs to manufacture a specific level of output.

$30.42 + $9.89 + $5.75 = $46.06

$50.00 - $46.06 = $3.94

2. 12 > 0

3. question 3 is wrong -2 = -2

4. -0.5 < 1

5. In the above operations, they did not effect the inequality sign because the same operation is being done to both sides, therefore the inequality sentences all remained true.

Step-by-step explanation:

1. (3)(4) < (7)(3)

(2)12 < 21(2)

(4)24 < 42(4)

(9)96 < 168(9)

= 864 < 1512

Answer:

C.$133

Step-by-step explanation:

You have to add all numbers then divide by how many numbers there are.

So, in this case, you must add 125 and 140 to get 265

Then you must divide by 2 since there are 2 numbers

265/2 = 132.5

Round to the nearest dollar

The final answer is $133

Step-by-step explanation:

yes the f( x) and g( x) is inverse each other.

f(x) = 3x-5

3x-5=0

x=5/3

g(x) = x+5/3

5x/3

x=3/5

-1/7 belongs to B. Rational numbers and F. Real numbers.

A set is a collecting of well defined objects one form of writing a set is in roaster method where we write the elements with commas and close them with second brackets.

According to the given question we have to select all the sets in which the number - 1/7 is an element.

[tex]\huge\blue{ANSWER}:—[/tex]

A solution for a pair of lines means that they are equal to each other. This occurs when they instersect. Since the lines have the same slope, but are not the same line, they are parallel, so they will never intersect. This means there are zero solutions.

The provided set of equations for the lines Q and S have no solutions.

The slope of a line is a measure of how steep the line is and is defined as the change in y divided by the change in x between any two points on the line. In other words, the slope is the ratio of the vertical distance between two points on the line to the horizontal distance between them.

Parallel lines are two or more straight lines that are equidistant from each other at all points and do not intersect, no matter how far they are extended in both directions. Parallel lines are often denoted by a double vertical line symbol (||) drawn between them.

In the given information:

Line Q crosses the y-axis at 3 and has a slope of one-half.

Therefore,

x=0 and y= 3

Straight line equation: y= mx + c

where m is the line's slope

The values in this equation should be replaced.

y= mx + c

3= (1/2) ×0+c

3 = c

y= (1/2) x + c

Line S crosses the y axis at -2 and has a slope of one half.

Thus, the c will be negative.

After that, the line's equation is y = (1/2) x - 2.

Use the equation to plot the graph.

So,

Line Q and Line S are parallel lines.

Due to the fact that it won't intersect, there is an equation.

Thus, the provided pair of equations for lines Q and S have no solutions.
