Answer:

distributive property, subtraction, division

Step-by-step explanation:

i don't know the exact name of the last two but that's what i'm assuming they're called lol

The properties used to solve the equation 4(x + 3) = 20 are the distributive property, subtraction property of equality, and division property of equality. First, the distributive property is used to expand the left-hand side, then subtraction is used to isolate 4x. Finally, division is used to find x = 2.

The question provides an algebraic equation and uses properties to solve for the variable 'x'. The steps taken demonstrate the following properties:

Answer:

D. $2,511

Step-by-step explanation:

First off, we need to write down the facts we know.

There are about 52.177 weeks in a year

Cesar works 28 hours each week

Cesar makes $23 an hour

There are 12 months in a year

Cesar has $3,360 after his monthly expenses

To figure out how many hours are in a "work year," multiply the number of work hours in a week by the number of weeks in a year. In other words, multiply Cesar's 28 hour work week by about 52.177 weeks. That makes 1,456 hours in his work year. That means he makes $33,492 a year. If you multiply $2,511 by the months in a year (12), you get $30132. Finally, subtract his annual salary by $30132 to get $3,360, which is what was left of Cesar's earnings after paying all of his monthly expenses. This means that your answer is: D. $2,511.

Answer:

D. $2,511

Step-by-step explanation:

$23 x 28 x 52 = $33,488

$33,488 ÷ 12 = $2,790.66 = $2,791

12($2,791) - $3,360 = 30,132

$30,132 ÷ 12 = [$2,511]

Answer:

GCF: (x - 2)

4 / (x + 5)

Step-by-step explanation:

The expression given is:

(4x - 8) / (x² + 3x - 10)

To find the greatest common factor, we have to factorise the numerator and denominator individually.

NUMERATOR:

4x - 8 = 4(x - 2)

DENOMINATOR:

x² + 3x - 10 = x² + 5x - 2x - 10

x² + 3x - 10 = x(x + 5) - 2(x + 5)

x² + 3x - 10 = (x - 2) ( x + 5)

So, the expression becomes:

4(x - 2) / [(x - 2) ( x + 5)]

We observe that the common factor in both numerator ad denominator is (x - 2).

This is the greatest common factor (GCF).

Factoring out (x - 2), the expression can be rewritten as:

4 / (x + 5)

Answer:

The terms in the denominator have a GCF of 1, so nothing gets pulled out in the denominator. The GCF of the terms in the numerator is 4.

Missing question:

An artist is making a rectangular canvas for a custom painting. the canvas has a width of 9 1/2 feet and a length of 13 1/4 feet . what is the area of canvas in square feet?

The area of a rectangle is given by the formula

[tex]A=L\cdot w[/tex] (1)

where

A is the area

L is the length

w is the width

In this problem, we have a rectangular canvas, so we want to find its area.

We know that:

[tex]w=9\frac{1}{2}ft[/tex] is the width, converting into an improper fraction,

[tex]w=\frac{9\cdot 2+1}{2}=\frac{19}{2}[/tex] ft

[tex]L=13\frac{1}{4}ft[/tex] is the length, converting into improper fraction,

[tex]L=\frac{13\cdot 4+1}{4}=\frac{53}{4}[/tex] ft

Substituting into eq (1), we can find the area of the canvas:

[tex]A=\frac{19}{2}\cdot \frac{53}{4}=\frac{1007}{8}=125.9 ft^2[/tex]

Answer:

Positive

Step-by-step explanation:

Slope: (6-4)/(45-30)

= 2/15

The slope of 2/15 miles/minute is positive, representing Robi's speed from the 4-mile mark to the 6-mile point of the race. It is calculated by taking the difference in distance and dividing it by the difference in time.

The question presented is dealing with the concept of slope, which is a foundational aspect of algebra and indicative of the rate of change in a given situation. In this context, the slope represents Robi's speed or velocity during a race. Since Robi has run the first 4 miles in 30 minutes and reached the 6-mile point after 45 minutes, we can calculate her average speed (slope) between these two points. To find the slope (rate), we can use the change in distance over the change in time, which in this case is:

Change in distance (miles) = 6 miles - 4 miles = 2 miles

Change in time (minutes) = 45 minutes - 30 minutes = 15 minutes

Then, we calculate the slope:

Slope = Change in distance / Change in time = 2 miles /15 minutes = 2/15 miles/minute

This slope is a positive value, indicating that Robi's speed is in the forward or positive direction. It is not negative, zero, or undefined.

Additionally, the information provided about the percentage of runners and their speeds gives us a context within which we can compare Robi's speed to understand her performance relative to other runners. It's important to note that these percentages do not affect the calculation of the slope.

Answer:

The only difference is: If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses.

Answer:

Step-by-step explanation:

The formula for the volume of a rectangular pyramid is

Here we have volume (V), base (L), and width (W)

V = 360 in³, L = 12 in, W = 10 in

We need to manipulate the volume equation to solve for the height (H)

First we need to multiply both sides by 3 to get rid of the fraction:  3V = L×W×H

Then we need to divide both sides by (L×W) to get:

Answer:

(7x + 10y)

Step-by-step explanation:

To find this add (3x - 4y) to itself to calculate to lengths of the shorter sides.

(3x - 4y) + (3x - 4y) = 6x - 8y

Subtract this from (20x + 12y)

(20x + 12y) - (6x - 8y) = 14x + 20y     Divide this by two to get the length of one side

14x + 20y / 2 = 7x + 10y

If this answer is correct, please make me Brainliest!

The expression for the other side of the rectangle, when one side is (3x-4y) and the perimeter is (20x+12y), is (7x + 10y).

To determine the expression for the other side of the rectangle with a perimeter of (20x+12y) and one side being (3x-4y), we must remember that the perimeter of a rectangle is calculated by adding together twice the length and twice the width (P = 2l + 2w). Since we have one length, we can solve for the width by dividing the perimeter by 2 and subtracting the length.

First, let's find half of the perimeter by dividing the given perimeter by 2:

(20x + 12y) / 2 = 10x + 6y

This represents the sum of one length and one width. We then subtract the given side (one length) from this to find the other side (one width):

(10x + 6y) - (3x - 4y) = 10x + 6y - 3x + 4y = 7x + 10y.

Answer:

1/16

Step-by-step explanation:

1/2 getting tails

1/4 getting tails twice

3/12 getting a J month =1/4

1/4 x 1/4 =1/16

Answer:

1/16

Step-by-step explanation:

Given a fair coin, the probability of getting tails on any one toss =

P(tails) = 1/2

if a coin is tossed twice and  we get tails both times,

P( 2 tails on 2 consecutive tosses) = (1/2)(1/2) = 1/4

Total number of months = 12 months

Months that start with J = January, June, July = 3 months

P(selecting months that start with J) = 3/12 = 1/4

Hence the probability of tossing 2 consecutive tails then selecting a month that starts with J

= (1/4) x (1/4)

= 1/16

Step-by-step explanation:

[tex]\sqrt{100}=10[/tex]  because [tex]10^{2}=100[/tex]. 10 is the square root of 100, which means that 10 multiplied by itself (10×10=[tex]10^2[/tex]) is equal to 100. So, when you are trying to find the square root of a number, the square root is itself multiplied by itself.
