Answer 1

Answer:

3r + 3/8 = 1

r = 5/24

Step-by-step explanation:

Working together, sam and charlie can change all the light bulbs in the office building in 3 hours. it would have taken charlie 8 hours to do the job alone.which equation can be used to solve for the rate, r, for sam to change all the light bulbs in the office building by himself?

For the rate, r, for sam to change all the light bulbs in the office building by himself?

One job is involved

3r + 3/8 = 1

3r = 1 - 3/8

r = 1/3 - 3/8÷3

= 1/3 - 3/8 × 1/3

= 1/3 - 1/8

r = 1/3 - 1/8

r= 8-3/24

r = 5/24

Area = Length x Width.

simple room measurement

Measure the length using the distance from one wall to the opposite wall.

Measure the width from wall to wall.

Add 2 to 4 inches to each side. This accounts for waste, doors and slanting walls. It’s easy to cut a little off for a perfect fit, but it’s impossible to add without creating unsightly seams.

Multiply the length times the width or enter those into the calculator above. This is your total square footage for that room.

Repeat this process for each room.

Stacy wants to go on a vacation that will cost her at least $1540. She has $1825 saved but has
$65 deducted every week from her paycheck to pay for her insurance. At most, how many
weeks can she have these deductions made in order to afford her vacation

Answers

Answer:

4 weeks

Step-by-step explanation:

First,, we should subtract the vacation price from her savings to get the base. That is 1835-1540=295. Then we can do 295/65,, and then we get 4  7/13. So,, she can only afford 4 weeks of these deductions in order to have enough money for her vacation.

12x + 8y = 24 Convert from standard form to slope-intercept form.

Answers

y= —12/8x + 3 is the slope into form because 12x + 8y = 24 minus 12x on both sides . 8y= —12x + 24 divide 8y by 8y and —12x + 24 over 8 you will get y = —12/8x + 3

The required equation is y = -(3/2)x + 3 in slope-intercept form.

What is the standard form of linear equations?

A linear equation is written in the standard form as Ax + By = C, where A, B, and C are integers and x and y are variables.

For example, 8x + 2y = 7 is the standard form of a linear equation in two variables.

The equation is given in the question, as follows:

12x + 8y = 24

Isolate the variable of y for the above equation,

8y = - 12x + 24

Divided both sides by 8 into the equation,

y = - (12x)/8 + (24)/8

y = -(3/2)x + 3

This equation is in slope-intercept form.

Answer:

La opción correcta es;

x² - 4·x·y + 4·y²

Step-by-step explanation:

La ecuación dada es (x - 2·y) ²

(x - 2·y) ² = (x - 2·y) × (x - 2·y) = x·x + x × (-2·y) + (-2·y) × x + (-2·Y) × (-2·y)

Lo que da;

(x - 2·y) ² = x² - x × 2·y - 2·y × x + (-2·y) ²

De lo que tenemos;

(x - 2·y) ² = x² - 2·y × x - 2·y × x + 4·y² = x² - 4·y × x + 4·y²

∴ (x - 2·y) ² = x² - 4·y × x + 4·y² = x² - 4·x · y + 4·y²

Y el resultado del cuadrado simplificado es (x -  ·y) ² = x² - 4·y × x + 4·y² = x² - 4 · x · y + 4·y²

La opción correcta es (x - 2·y) ² = x² - 4·x · y + 4·y².

Step-by-step explanation:

In order to find the length and width necessary to find area, we need to look at the chart. By exmaining, we can see that the length is two units from top-to-bottom. We can also see that the width is 4 units from left-to-right. We can now multiply 4 times 2 to get our answer of 8.

Answer:

B. 8.0

Step-by-step explanation:

To figure out the area you just do length times width, and you find the two by counting the amount of squares they take up. The length is two, and the width is 4; therefore the area is 8

Find two consecutive odd numbers such that seven times the smaller number is 17 more than six times the larger

Answers

Answer:

29 and 31

Step-by-step explanation:

Let

x = the first odd number

x + 2 = the second odd number

seven times the smaller number is 17 more than six times the larger

7*x = 17 + 6(x + 2)

7x = 17 + 6x + 12

Collect like terms

7x - 6x = 29

x = 29

x + 2 = 29 + 2

= 31

Check:

7*x = 17 + 6(x + 2)

7*29 = 17 + 6(29 + 2)

203 = 17 + 6(31)

203 = 17 + 186

203 = 203

Therefore, the two consecutive odd numbers are 29 and 31
